1906年,美国一家金属研究所正在研究一种新的合金材料。一个小伙子不小心将一把钳子掉进热水盘里。这是事故,小伙子赶紧趁没人注意时,偷偷地去捞那把钳子,他捞起来一看,吓呆了,这哪里是钳子,简直是两根直通通的铁棍!这时,实验室的主任发现了他,笑眯眯地问:掉下去的是什么?为什么这样惊慌?小伙子低声把事情经过说了一遍,实验室主任认为有些蹊跷,顺手将另一把钳子扔进了热水盘。取出来一看,果然变成了直铁棍。主任马上把相同质料的钳子送到化验室化验,才知道这几把钳子全是镍钛合金制造的。它为什么在掉进热水之后,恢复加工前的模样呢?它是不是有了记忆能力?这不成了长脑袋的金属了吗?经过多次研究,科学家们终于弄清了能在加温后恢复原来形状的记忆金属。这种金属后被广泛应用于科研、生产中。
In 1906, a metal research institute in the United States was studying a new alloy material. A young man inadvertently dropped a pair of pliers into the hot water dish. This is an accident, the young man quickly while nobody noticed, secretly to go fishing for the pliers, he picked it up and looked scared, where is the pliers, is simply two straight through the bar! At this time, the laboratory The director found him, smiling and asked: What is falling? Why so panic? The young man whispered things say again, the laboratory director think something strange, easily throw another pliers into the hot plate. Take a look, it turned into a straight bar. Director immediately sent the same material pliers to laboratory tests, we know that these pliers are all made of nitinol. Why does it return to its pre-processing look after it has dropped into hot water? Does it have the ability to remember? Did not it become the metal of the head? After several studies, scientists finally figured out that after warming Restore the original shape of the memory metal. After this metal is widely used in scientific research, production.
