典型的形状记忆合金———ＮｉＴｉ合金价高 ,作为管接头只好用于军工中。铁系合金原材料价格便宜 ,但形状记忆效应差 ,为改善其性能 ,需进行训练热处理 ,方能达到高的形状记忆效应。物质材料研究机构的菊地等研究人员采用温轧法 ,即在形成记忆效应的时效处理前进行轧制 ,从而 Typical shape memory alloy --- NiTi alloy high price, as a pipe joint had to be used in military. Iron alloy materials, cheap raw materials, but the shape memory effect is poor, in order to improve its performance, the need for training heat treatment, in order to achieve high shape memory effect. Researchers at Kikuchi, a research institute for materials and materials, use a warm-rolling method in which rolling is performed before the aging treatment for forming a memory effect
