据《世界金属导报》1993年9月6日报道,北京科技大学铁基形状记忆合金组研制成功Fe-Si-Mn系形状记忆合金无缝钢管,并制成管接头。由于采用了微量元素处理,热、冷加工性能优异,所制无缝钢管及接头的成品率达90%,其加工性能、记忆效应优于美、日、俄等国的同类产品。 According to the “World Metal Herald” reported on September 6, 1993, the Fe-Si-Mn shape memory alloy seamless steel pipe was successfully fabricated in the iron-based shape memory alloy group of University of Science and Technology of Beijing and was made into a pipe joint. As a result of the use of trace elements, heat, cold workmanship, seamless steel tubes and joints made of the finished product rate of 90%, its processing performance, memory effect is better than the United States, Japan, Russia and other countries of similar products.
