Chemical Bath Deposition of Zinc Sulfide Based Buffer Layers Using Low Toxicity Materials.

Although the majority of fiber reinforced resins contain glass fibers, the attractive properties of carbon fibers have made them a material of choice in various applications [4].
Since nowadays, carbon fiber thermoplastic composites are widely used in various applications, it is essential to know about the thermal properties of these materials.
Experimental Materials PTFE powder with a grit size about 65.0 μm was used as matrix resin of CF/PTFE composite.

The strength of a final product of steel is affected by its final austenite grain size.Almost applied models for grain growth based on Beck and Sellars equation , which has the isothermal condition assumption; whilst most of the materials processing take place under non-isothermal condition.
Most of the materials processing operation involve heating and cooling and the material experiences spatial and temporal variation of temperature during processing.

The stainless steel and Ni-base superalloy are two general valves materials, however, its higher density is not benefit to automotive lightweighting[1-3].
Because the materials with bcc crystal structure have a relatively larger number of slip systems, the deformation is easily.
Although the slip systems are few for materials with hcp crystal structure, it is quite brittle, thus more easily are broken into granule by applied force [9,10] .
