1928年,英国有一位名叫森金斯的科学家在实验中发现,一些金属经过高温处理或添加某些元素之后,会变得像面团一样柔软和易于加工。只要施加很小一点压力和拉力就可以延长几倍、几十倍以至几千倍。于是,他便把这种现象称为超塑现象,并把具有这种特性的金属称为超塑金属。超塑金属可以说是金属中的“变形金刚”。到目前为止,人们发现的超塑金属多达一百几十种。其中比较普遍的是纯镍、铁镍铬合金、钛合金 In 1928, a scientist named Senkins in the United Kingdom found in experiments that some metals become soft and easy to process like dough after being treated with high temperature or adding certain elements. It can be extended several times, several times or even several thousand times as long as a little pressure and tension are applied. He then referred to this phenomenon as superplasticity, and called metal with such properties as superplastic metal. Superplastic metal can be said to be “Transformers” in metals. So far, as many as one hundred and dozens of superplastic metals have been discovered. The most common of these are pure nickel, iron-nickel-chromium alloys, and titanium alloys.
