According to Eq. 3, different materials with different conductivity had different resistance, so did the thickness.
Also it supported the user creating new materials as shown in Fig. 3.
Table 2 Parameters of the model Material Conductivity (W/m·K) Al2O3 27.598 Baseboard BeO 230 AlSiC,SiC 160 Table 2 gave the materials of each part usually used.
The Al2O3 baseboard had a higher speed compared with others. .Materials of BeO and AlSiC had a better stability.

The thermoelectric device is made up of two legs of different materials, freely suspends across two heat sinks (also electrodes) kept at the initial temperature, which act as the cold end.
Due to the Seebeck effect of the thermoelectric materials, the temperature difference between thermoelectric component and heatsink surface will generate a DC thermoelectric potential.

Study on Deformation Law of Drum-Shaped Blank and Collapse Defect in Rolling Process Leigang Wang 1, a, Dezhi Kong 1, b, Jiayang He1, c, Yao Huang1, d 1School of Materials Science and Technology, Jiangsu University, Zhenjiang212013, China algwang@ujs.edu.cn, b547961870@qq.com, cjiayanghe_2006@126.com, dyaoye90@126.com Keywords: ring rolling; drum-shaped blank; collapse Abstract.
With its advantages of higher utilization ratio of material, better product quality and working conditions, and lower production cost [2,3], it will gradually replace the traditional process such as open die forging, broaching with frame, bend welding, and become the preferential forming technology for the production of seamless rings [4].
The rigid plastic constitutive modeling of 42CrMo is selected from the material library of software simufact.forming for the rolling blank.
