In this paper, the calculation of the misalignment of the zirconium alloysof the two groups of A and B in different textures is carried out. According to the mismatch principle of film growth, the nucleation planes of the surface of the A combination alloy are mainly (200), (020), (002) three crystal planes, and the crystal plane mismatches with the growth crystal planes (104), (105), (106) exceeds 65% ; on the other hand, the nucleation planes on the B-composite alloy surface are mainly (011), (110), (101), (102), and (103) crystal planes, which are only 40% or lower with the growth crystal plane mismatch.

With the development of social economy, composite materials enhance thepractical application of non-ferrous metal materials in production, meet the needs of current development, and better promote the development and progress of related industries. The application of composite reinforced non-ferrous materials is to add non-metallic reinforcing materials to non-ferrous materials, so that the properties of the original materials can be better changed to form a new composite material. This composite will have better performance than the original material and can meet deeper applications of non-ferrous materials. In this paper, the research on composite reinforced non-ferrous materials will focus on the analysis of the performance of non-ferrous materials. It is hoped that the research in this paper can provide some references and suggestions for the development of non-ferrous materials.

Graphene is a two-dimensional hexagonal monoatomic layer crystal composed of carbon atoms, which exhibits the shape of a honeycomb and plays an important role in the fields of optics and mechanics. It also has the advantages of high specific surface area, strong chemical stability and special planar structure.

Micro-sized copper powder (99.95%; O≤0.3) has been shock-processed with explosives of high detonation velocities of the order of 7.5km/s to observe the structural and microstructural sub-strengthening. Axisymmetric shock-consolidation technique has been used to obtain conglomerates of granular Cu. The technique involves the cylindrical compaction system wherein the explosive-charge is in direct proximity with the powder whereas the other uses indirect shock pressure with die-plunger geometry. Numeric simulations have been performed on with Eulerian code dynamics. The simulated results show a good agreement with the experimental observation of detonation parameters like detonation velocity, pressure, particle velocity and shock pressure in the reactive media. A pin contactor method has been utilized to calculate the detonation pressure experimentally. Wide angled x-ray diffraction studies reveal that the crystalline structure (FCC) of the shocked specimen matches with the un-shocked specimen. Field emissive scanning electron microscopic examination of the compacted specimens show a good sub-structural strengthening and complement the theoretical considerations. Laser diffraction based particle size analyzer also points towards the reduced particle size of the shock-processed specimen under high detonation velocities. Micro-hardness tests conducted under variable loads of 0.1kg, 0.05kg and 0.025kg force with diamond indenter optical micrographs indicate a high order of micro-hardness of the order of 159Hv. Nitrogen pycnometry used for the density measurement of the compacts shows that a compacted density of the order of 99.3% theoretical mean density has been achieved.

Silver nanofluid was prepared by bio-reduction reaction between orange peels extracts (OPE) and silver nitrate and characterized by spectroscopic and microscopic techniques. Colloidal nanoparticles of sizes between 40 – 50 nm and spherical shape were obtained. The nanofluid was applied as anticorrosion additive to inhibit corrosion of X80 steel in simulated oilfield scale dissolver solution (1.0 M HCl) at various temperatures. The nanofluid (OPE-AgNPs) was 98.9 % and 84.3 % efficient at 30 ºC and 60 oC respectively as determined by weight loss measurement. In comparison with OPE, OPE-AgNPs shows better corrosion inhibition and higher resistance to thermal degradation. Some kinetic and thermodynamic models were used to characterize the inhibition process. OPE-AgNPs could be optimized and used as alternative anticorrosion additive for scale dissolution liquor in the industry.
