The effect of Silicon dioxide (SiO2) powder on weld bead geometry, Heat affected zone (HAZ), and micro-hardness of SS304 grade Austenitic stainless steel weld was investigated. SiO2 improves the weld bead penetration with a simultaneous reduction in bead width. The improvement in penetration results from arc constriction and reversal of Marangoni flow. The results demonstrate SiO2 flux can increase the heat density by arc constriction and Marangoni convection. The temperature in HAZ reaches above the recrystallization temperature and consequently leads to the formation of new grains. The new grains formed in HAZ are of a very large size as compared to parent metal grains. Due to Larger grains, the micro-hardness in HAZ area was found to be less than weld metal and base metal zone. Increased heat density by using SiO2 flux increased the size of Heat Affected Zone.

In the present paper joining of aluminium alloy-AA1100 and low carbon steel (LCS) plates has been carried out using explosive welding technique. Welding parameters were optimized in order to achieve uniform and good quality welds. Optical and scanning electron microscope (SEM) were employed to observe the morphology and microstructure at the interface boundary. Mechanical properties of weld joints have been evaluated by carrying out ram tensile and hardness test. After successful joining of plates, the bonding interface had laminar morphology free from major cracks. No delamination was observed at the interface of the clad plate when subjected to chisel test. The bonding strength of the weld joint was more than the strength of weaker material.

The constraints with the applicability and technological limitation of metal and alloy lead to the origin of advanced ceramics products or devices to enhance the system productivity and effectiveness. Advanced ceramics matrix composites (CMCs), metal nanocomposites are prepared by pressing and high-temperature sintering. The excellent properties of ceramics are preserved by the amalgamation of metal or semiconducting phase with the convention ceramics. Electro-discharge machining (EDM) has the capability to machine very rigid to cut materials that are extremely difficult to the shape by any other regular method. In the past decade, many types of research have explored machining of advanced ceramics by EDM process and came out to be some unique process to machine even non-conventional ceramics and CMCs. Many research have been found in the field of hybrid EDM process to improve the machining outcome and more efficient use of the EDM tool. One of the revolutionary findings is to machining of non-conductive advanced ceramics by EDM process. In the present paper, a critical review of advanced ceramics machining by EDM and its hybrid for ceramics and its composite are presented.

An experimental study has been carried out to investigate the tensile and flexural characterization of polymer hybrid composites made by reinforcing Jute, Pineapple leaf fiber, Copper foil and Aluminium foil into a epoxy resin. The weight fraction of composites was maintained at 40% fiber, 45% resin and l5% foil and the variation of mechanical properties such as tensile and flexural properties in each case were studied. The tensile strength was maximum in jute and pineapple composite. Further, the Flexural strength of the composite also maximum in jute and pineapple composite.

Hollow products are increasingly employed for automotive parts to reduce vehicle weight. Hydroforming technology is widely used for forming complicated or complex components from tube blanks. Complex shape can be easily formed with the help of high pressure. However high pressure equipments and high tonnage press are the resistance to product cost benefits. Whereas low pressure tube hydroforming can also achieve some of the complex shape with minimum pressure requirements and lower die closing force. This work represents the forming of two dimensional different complex shapes by using the low pressure tube hydroforming. The die filling conditions were critically studied. It is determined that for the complex shape with low pressure tube hydroforming slightly lesser perimeter length is required which allows for weight reduction. Stress and thickness distribution of the part during tube crushing were analysed.

ZA alloys are known as bearing materials due to its excellent tribological properties. Many researchers have worked on evaluating mechanical, wear, bearing, damping properties of ZA alloys processed through various casting techniques. From previous literature it is known that increase in the aluminium content increases mechanical properties of ZA alloys and also increases fluidity of the melt in continuous casting process, In the present work an attempt is made to study the effect on fluidity by increasing aluminum content in zinc alloys processed through centrifugal casting at rotational speed of 600rpm. ZA 8, ZA 12 and ZA 27 alloys were taken for the study to understand the effect of aluminum in ZA alloys during centrifugal casting process. Uniform cast tube was formed for ZA 8 alloy and non-uniform cast tubes were formed for other two alloys due to the increase in aluminum content which probably restricts fluid motion. The detailed discussion on fluid flow, microstructure and hardness of the cast tube were discussed finally.

The current work focuses on analysis of four caseshorizontal hole pair in uniaxial loading, Horizontal hole pair in biaxial loading, Vertical hole pair in uniaxial loading and vertical hole pair in biaxial loading. Readings obtained are characterized by three methods; Analysis by FEM, analytically by theoretical calculations and experimental by result obtained as per standard data handbook. Results clearly indicate that finite element analysis has shown profound abilities to determine the stress concentration factor as compared to the analytical and experimental counterparts. This clearly indicates that finite element analysis can be used as a significant tool to understand the behavior of plates subjected to varied loading conditions.

Now a day the work on the natural fiber based composites has been increased due to the factors such as depleting resources like petroleum, crude oil from which the synthetic fibers are produced, increasing environmental concern, increased global warming...etc. moreover some of the natural fibers exhibit high mechanical properties such as high tensile modulus in comparison with their synthetic fiber counter parts. In this study we have prepared and experimentally characterize the mechanical properties of the banana/ Americana hybridized composite material. Two different fiber weights were considered to also study the influence of the fiber weight on the mechanical properties of the hybrid composite. The properties such as tensile modulus, tensile strength, flexural modulus and strength, impact strength were found out. It was found that the mechanical properties of the hybrid composite were increasing with the increase in the fiber weight.
