Влияние добавок и лигатуры на фазовые превращения в бронзе с эффектом памяти формы. Структурные изменения в бронзах после искусственно

摘要

The influence of B, Ni, Ti and AI-Ti-C-N alloy additions on phase transformations and structure of the shape memory bronze Cu-122AI-4Mn was investigated with the use of direct thermal analysis. It was marked that boron modification of aluminum bronze as well as micro alloying with AI-Ti-C-N alloy leads to increasing thermo-mechanical properties. On the hypothesis of metasfable cluster groups initiation is explained a mechanism of the structure forming in bronze Cu-12AI-4Mn. Conclusions about the thermal stability of investigated alloys have been made.
