Analysis of Influence Parameters on Axial Movement Displacement about Cross Wedge Rolling Asymmetric Shaft Part Wenfei Penga, Kangsheng Zhangb and Zhenghuan Huc School of Mechanical Engineering, University of Science and Technology Beijing, Beijing 100083, P.R.China arandypwfafei@yahoo.com.cn, bZhang.ks@me.ustb.edu.cn, ᶜhuzhengh@public.bta.net.cn Keywords: CWR, Asymmetric shaft part, Axial movement displacement, Influence parameter Abstract.
Temperature only influences on resistant of material, the geometry of deformation zone don’t change, so instantaneous sketch keeps constant in different rolling temperature, the volume of metal which transfers to larger theoretical axial force keeps constant, it produces the same axial movement speed, and the same axial movement displacement.

Introduction Before the twentieth century, Sn/Pb solder alloy was commonly used as electronic welding material owing to its high quality and low cost.
The alloys were weighed by balance and then put the alloy material into the furnace for melting.

Very few materials are qualified for this specification and indium tin oxide (ITO) has dominated the TCO market up to date.
However, due to resource scarcity of indium, various materials have been proposed for replacing ITO to fulfill growing demands for TCO in different applications.

Therefore it is selected as workpiece material in this study.
Chemical composition of the work material is listed in Table 1.
It is obvious that micro-hardness of the white layer, which extends to 970HV, is higher than that of the bulk materials, which is about 650HV.
