SHS method is being used for obtaining of refractory compounds, intermetallics, ceramics and materials based on them.
Combining in one technological stage of SHS process and shear deformation of synthesis products allows to get non-porous high-strength materials.
In [2] mathematical model of deformation and thermal processes of compaction of viscous compressible materials was proposed.
The model of a viscous medium is used often as the rheological model to describe the behavior of powder materials.

These approaches are intuitive, but, considering the requirement of collecting a large number of instance samples in the training, they costs a lot of manpower and material resources.
Inspired by the recent success of particle swarm optimization (PSO) [5] in effective and efficient determination of optimal (or global) solutions for hard science and engineering problems, we employ the PSO algorithm to find the optimal transformation in Equation (2).

Further, resistance welding of magnesium requires a backup plate made of steel to conduct the heat to the workpiece material.
This led the automobile manufacturers for the increased use of magnesium alloy base materials for manufacturing automotive components.
Currently resistance spot welding is generally used in welding automotive materials mainly composing of steels.
After 1200 rpm, the frictional heating is high such that material flow occurs while spot welding.

Introduction
The friction and wear is an important factor that makes parts ineffective, while the friction and wear course mainly happen on the surface of the material, preparing hard wear-resistant coating on the surface of the material could improve the wear resistance of the material, but when increasing the hardness of the surface, the wear of counterparts increase, which make the expectancy life of the friction couple decrease.
When MoS2 in the coating rub with other material, it could form solid lubricate film which effect lubricate between two surfaces, thus improving the wear resistance.
