Abrasive water jet machining (AWJM) is one of the most developed non-traditional machining processes. It is generally used to cut difficult to cut materials like composites. The present study is focused on machining of carbon fiber vinyl ester composite with AWJM. The effect of process parameters namely water pressure, standoff distance and traverse speed on surface roughness and kerf tapper is studied. Design of experiment is done by using Taguchi L16 orthogonal array. It is observed that water pressure is the most significant parameter followed by traverse speed. It is found that with the increase in water pressure and decrease in traverse speed of AWJM, surface roughness and kerf tapper of machined samples decreases.

The present study aims to study the wear properties of as forged Inconel 690. The dry sliding wear behavior of as forged Inconel 690 is studied in accordance with ASTM standards G99 i.e. dry sliding on pin on disc wear test apparatus. Three wear parameters namely normal load, sliding distance and sliding velocity were considered in this study. The experiments for wear loss have been conducted as per Taguchi Design of experiments. An L27 Orthogonal array was employed for this purpose. The wear loss obtained for As Forged Inconel 690 is predicted by the Neural Network Toolbox of MATLAB R2015a using the Levenberg-Marquardt (trainlm) algorithm which trains the feed forward neural network having 3-6-1 (three input neurons, six hidden neurons in the single hidden layer and one output neuron). Experimental data sets from obtained from L27 Orthogonal array have been utilized to develop ANN. The results concluded that error for wear loss of As Forged Inconel 690 lies within 10% between experimental data and neural network prediction

The present paper describes the experimental investigation on influence of process parameters on maximum forming force in Single Point Incremental Forming (SPIF) process using dummy sheet. Process parameters namely dummy sheet thickness, tool size, step size, wall angle and feed rate are selected. Taguchi L18 orthogonal array is used to design the experiments. From the analysis of variance (ANOVA) dummy sheet thickness, tool size, step size and wall angle are significant process parameters while feed rate is insignificant. It is found that as dummy sheet thickness, tool size, step size and wall angle increase magnitude of peak forming force increases while there is marginal decrease in forming force as feed rate increases. Predictive model is also developed for forming force. Validation tests are performed in order to check the accuracy of developed model. Optimum set of process parameters is also determined to minimize forming force. Experimental results are in good agreement with results predicted by the developed mathematical model.

A new analysis for cold rolling of thin strip and foil is developed. This model follows the approach of Fleck et al [8], but relaxes their assumption of a central flat neutral zone. Instead of following their inverse method to obtain the pressure distribution in this neutral zone, an explicit equation for the contact pressure variation is obtained from the sticking condition in this region. This significantly simplifies the solution method, leading to a much more robust algorithm. Moreover, the method treats the cases either where the roll retains its circular arc or where there is very significant roll deformation in the same way, greatly simplifying the method of obtaining solutions. This will facilitate the incorporation of other effects such as the friction models currently being developed. Results are in line with the theory of Fleck et al [8]. The effect of entry and exit tensions on the nondimensional load and forward slip is investigated. It is found that the effect of equal entry and exit tensions is equivalent to reducing the yield stress of the strip by this tension stress.

This study addresses the effect of process parameters viz., loading ratio (mass of explosive/mass of flyer plate) and preset angle on dynamic bend angle, collision velocity and flyer plate velocity in dissimilar explosive cladding. In addition, the variation in interfacial microstructure and mechanical strength of aluminium 5052-stainless steel 304 explosive clads is reported. The interface exhibits a characteristic undulating interface with a continuous molten layer formation. The interfacial amplitude increases with the loading ratio and preset angle. Maximum hardness is observed at regions closer to the interface

Similar joints of DP800 (Dual Phase) steel in lap joint configuration were fabricated using resistance spot welding (RSW) process. The process parameters were optimized using DOE (design of experiments) and the welds joints were fabricated using the obtained DOE matrix. The tensile shear fracture load (TSFL) of joints was evaluated using universal testing machine. Microhardness variations across the weld cross-section was recorded using Vickers’s microhardness tester. Microstructural features were analyzed using optical microscopy (OM) and scanning electron microscopy (SEM). From this investigation, it is understood that increase in welding current increases the nugget zone size and it led to increasing the degrease of softening in the HAZ. The tensile shear strength is found to increase with increase in welding current up to a certain limit and then it decreases. The microhardness profile shows a peak hardness in nugget zone and the hardness is lower in the HAZ. The softening of HAZ is mainly attributed to inter-critical heating during welding.

Gas turbine engines demand material with unique properties like high-temperature oxidation and corrosion resistance, high specific strength, etc. All over the world material development to meet these requirements has led to the development of novel alloys. While Titanium base alloys are used in the low-temperature regime of the gas turbine engine, Nickel-basedsuperalloys are used for hot end components of the engine. With the increase in the temperature requirement for the turbine parts, the form of the Ni-based superalloys changed from wrought to cast superalloys. As an inherent process of investment cast superalloy blades and vanes which has serpentine passages for air cooling, these passages are required to be closed after casting. The numerous adapters also need to be joined on the cast superalloy casings for various instrumentation, lube oil ports. These cast superalloys are nonweldable and joining these pose a challenge. In this present investigation, the joining of the Nibasedsuperalloy BZL12Y and martensitic stainless steel AE961W using rotary friction welding process. The mechanical properties of the dissimilar joints were evaluated as per the ASTM standards. Microstructural features of various regions of welded joints using optical microscopy (OM) and scanning electron microscopy (SEM). The material is welded in different condition to obtain the maximum tensile strength of the weld joint. From this investigation, it was found that the combination of aging and h & t condition weld joint gives good strength and a stable hardness value. Correlation between tensile properties and microstructural features were analyzed and reported in this paper.

In today’s world refrigeration systems play a vital role to fulfil the human needs. A continuous research is being carried out by many researchers in order to improve the performance of these systems. Presently used, vapour compression refrigeration system does not work efficiently due to shortage of electric power. This study covers a broad overview of solar photovoltaic technology, which uses easily available solar energy for refrigeration purpose. It includes a motor, a compressor, an inverter and battery, a photovoltaic controller and panels. This can be done by converting solar energy in to electricity by means of photovoltaic devices, which can be utilized by the electric motor to drive vapour compression refrigeration system. The main objective of the study is managing the shortage of electric power, in living environments by using a cooling system coupled to a solar installation. In this solar refrigeration system, when conventional refrigerants like (R22, HFCR134a, R600, etc.) are used it leads to low thermal conductivity, heat transfer rate and COP level and some of the other impacts are acid rain, melting of glaciers, sea level raising, health impacts, atmospheric pollution, ozone depletion, which is very hazardous to the environment. To avoid these threats, one of the ways is to use nanofluids which are not harmful to the environment. The usage of nanofluids results in high thermal conductivity, heat transfer rate and give better COP level. The following three nanofluids Al2o3, Zro2, Cu2o have been already used in the refrigeration system. Some of the properties of given nanofluids will be changed to innovate new nanofluids. The innovated nanofluids will be used in refrigeration system and the same will be compared with other nanofluids like R22, R134a, R290, and R600a. Even though Al2o3, Zro2, Cu2o gives good results, the new nanofluids have been innovated for better results.
