Improvement of the shape memory characteristics of a Cu-Zn-Al alloy with manganese and zirconium addition
- City Univ. of Hong Kong, Kowloon (Hong Kong)
Cu-based shape memory alloys (SMAs) possess good shape memory effect (SME) and have the advantage of lower price than Ti-Ni SMA. However, there are still some problems which should be solved before they can be used widely. Addition of suitable alloying elements can improve the mechanical properties, stabilization of martensitic transformations and also the SME of Cu-based SMAs significantly. Cu-Zn-Al is an important Cu-based SMA that suffers from the martensite stabilization and intergranular cracking in the processing procedures and service. As a modification of Cu-Zn-Al SMAs, the effects of Mn and Zr addition on the structure and martensite transformation behavior of different heat treated Cu-21Zn-6Al-1Mn-0.5Zr (wt%) SMA have been studied and compared to that of Cu-21Zn-6Al (wt%) SMA in the present paper.
