Abstract:The effect of Mn content on kinetic parameter during phase transformation in CuZnAlMnNi shape memory alloys at different rising or falling rates of temperature was studied by using the technology of differential scanning calorimetry. It indicated that there is no linear relationship between the variation of apparent activation energy and frequency factor, and the Mn content during phase transformation.

 

Key words: Mn content CuZnAlMnNi shape memory alloy phase transformation kinetic parameter
