СПІКАННЯ ПОРИСТИХ МАТЕРІАЛІВ З ПОРОШКІВ І ВОЛОКОН СПЛАВУ Сu - 12 % Аl - 3,5 % Мn З ЕФЕКТОМ ПАМ’ЯТІ ФОРМИ

Abstract

The process of vacuum sintering under loading of porous powder and fiber Cu - 12 % Al - 3.5 % - Mn shape memory alloy materials was investigated. The quality sintering of porous po¬wder materials wasachieved. It is established that the abnormal growth of grain size in Cu - 12 % Al - 3.5 % Mn fiber materials occurred because high temperature treatment at sintering under loading. It is reason for intergranular cracking of Cu - 12 % Al - 3.5 % Mn fiber materials
