NT-2合金是专门用于生物医学工程领域而研制的镍钛合金,它和一般形状记忆合金不同,除应具有独特的形状记忆功能外,还要求无磁,耐蚀,高疲劳等特性。本文介绍了合金的研制过程,包括合金成分选择,熔炼、加工、热处理工艺确定;系统测试的机械物理性能;
NT-2 alloy is a nickel-titanium alloy specially developed for biomedical engineering. Unlike conventional shape memory alloys, NT-2 alloy requires non-magnetic, corrosion-resistant and high-fatigue properties in addition to its unique shape memory function. This article describes the alloy development process, including the choice of alloy composition, smelting, processing, heat treatment process determination; system testing of mechanical and physical properties;
