Shimizu Tetsuhide等人首先对纯钛箔材的通电加热效果进行了基础性验证实验。开发了内藏通电加热电极的拉伸试验用夹具,并在万能力学试验机上对厚度为50μm的纯钛箔材进行不同方向、不同温度的拉伸试验,实验温度为25、300、450℃。结果表明,随着加热温度的提高,钛箔材在各方向的拉伸强度差异缩小。此前,T.Ikushima等人研究发现,当温度为700~1 000℃时,随着箔材厚度的减少,特别是当箔材厚度在0.1 Shimizu Tetsuhide, who first conducted a basic verification experiment on the electrical heating effect of pure titanium foil. Tensile test jigs with built-in heating electrodes were developed. Tensile tests were conducted on pure titanium foil with thickness of 50μm in different directions and different temperatures on universal mechanical testing machine. The experimental temperature was 25,300,450 ℃. The results show that with the increase of heating temperature, the tensile strength of titanium foil in all directions decreases. Earlier, T.Ikushima et al. Found that when the temperature is 700 ~ 1000 ℃, with the foil thickness decreases, especially when the foil thickness of 0.1
