美国、英国、苏联、日本等主要国家都在大力研制和发展记忆合金品种及其用途,这几年日本在这方面投入较多的力量,因而取得了较显著的进展,其特点是开发记忆合金的应用领域。新开辟的新用途有: (1) 用作电灯及雨伞开启用的启动装置。日本的同和矿业公司使用铜系形状记忆合金制成了电灯和雨伞自动开启机构。 (2) 激励装置。日本的横浜东洋公司利用镍-钛(Ni-Ti)形状记忆合金制成干燥机小 Japan, the United States, Britain, the Soviet Union, Japan and other major countries are vigorously developing and developing memory alloy varieties and their uses. In recent years, Japan has devoted more efforts to this area and has made remarkable progress. It is characterized by the development of memory alloy Application areas. Newly opened up new uses are: (1) for lighting and umbrellas used to start the device. Japan’s Tonghe Mining Company made use of copper shape memory alloy lamp and umbrella automatic opening mechanism. (2) excitation device. Japan’s Yokohama Toyo company using nickel-titanium (Ni-Ti) shape memory alloy made of small dryer
