Objects with titanium alloy, aluminum alloy and stainless steel materials are tested and analyzed.
Introduction Young’s modulus is one of the most interesting elastic features of materials for determining the material behavior in relation with deforming forces.
The sample materials are aluminum alloy Ti-6A1-4V, aluminum alloy 7075-T651 and stainless steel 303 separately.
Young’s Modulus of three different materials is measured.

It is highly attractive for solid mechanics applications, especially to new materials, such as IR window materials.
It can be used both in a reflection mode (for opaque materials) and in a transmission mode (for transparent materials).
CGS is very effective for the fracture study of IR window materials.

At present, the SLS technology material uses powder materials such as metals, ceramics, polymers [4-6].In this paper, the designed wood plastic composite materials have low cost, good dimensional stability, pollution-free, easily degradable and other advantages, and is suitable for SLS technology.
Results and Analysis of Simulation Experiment Forming Process of the Wood Powder/PES Composite Materials SLS.
In the simulation ratio of 1:4 of wood powder/PES composite powder materials are used.
So the error of PES/wood powder composite materials sintering is bigger.

In order to improve the machinability and electrical performance of the Ag electrical contact materials.
At present, traditional Ag/CdO materials have been replaced gradually by some new contact material such as Ag/SnO2 because of its damages to the environment and human health in the process of making and using[1-2].But Ag/SnO2 materials have innate shortcomings.
All of the above limited the manufacturing and application of Ag/SnO2 electrical contact materials greatly.
The higher the Ti content, the greater the materials’ hardness.
