Cross rolling method is effective for the imposition of a severe shear straining on rolled materials leading to an improvement of mechanical properties and formability of magnesium alloy sheets [11].
There is a strong bonding between these two materials.

However, in the process of the heat treatment, the rapid heating and rapid cooling will result in the residual stress in the materials of aluminum alloy.
The effects of residual stress in materials can be considerable with respect to, for instance, fatigue, fracture, corrosion, wear and friction.
Experimental The high strength aluminum alloy 2A02 forging round bars with diameter in 60mm were provided by Beijing institute of aeronautical materials.

Introduction The outstanding properties of boron carbide, such as extremely high hardness, chemical stability and low specific weight, make it an attractive component for hard and wear-resistant materials.
Since there is no chemical reaction between the two materials, it is possible to pair these compounds to make composites.
Pairing boron carbide and titanium diboride in a composite can be beneficial for the design of thermoelectric materials and composites with increased fracture toughness and bending strength relative to pure boron carbide.

As an effective technique, the microwave irradiation method has been proposed for preparing many functional materials [12] including the LiFePO4 phase [13].
The test electrode was produced by dispersing active materials (70 wt %), carbon black (20 wt %), and a poly(vinylidenefluoride) binder (10wt %) in N-methylpyrrolidone (NMP) solvent to form a homogeneous slurry.
These organic groups increased the internal resistance of the cathode materials, leading to a low capacity and large polarization.

Materials and methods The coatings were made on the Rzeszów University of Technology using a Cham Pro-Thermal Spray Systems manufactured by Sulzer company (Fig. 1).
During the manufacturing process the coating material in powder form is introduced into the plasma stream and then applied to the surface of the substrate material.
The next reason of cracks could be large differences between the coefficient of thermal expansion of deposited materials and the substrate (Fig 4a).Some particles did not fully melt into the flame retained in the coatings.
