Hot workingrefers to the process where metals are deformed above their recrystallizationtemperature and strain hardening does not occur. Hot working is usually performed at elevatedtemperatures. Lead, however, is hot-worked at room temperature because of its low meltingtemperature. At the other extreme...
Some metals expand when it is hot and c___ when it is cold. 相关知识点: 试题来源: 高一英语期中试卷带答案解析 解析 ontract 答案:contract 本题考查单词拼写. 根据题意及首字母提示英语中收缩的单词是contract.又本句主语是metals, 所以用contact.故填contract.有些金属热时膨胀,冷时收缩本题考查单词...
By using a narrow x-ray fan beam to measure the strip, the system can record the height of each point of the strip in the time domain, and the flatness, or shape, of the strip can be calculated. Want to know more about hot and cold rolling of steel? Here are our top five ...
