摘要: Abstract The effect of γ precipitates on the martensitic transformation in CuZnAl shape memory alloys has been studied. Characteristic temperatures, thermal energy released and entropy changes have determined by means calonmetry with simultaneous acoustic emission detection. non-chemical contributions, elastic frictional, present this kind also estimated for several precipitate distributions. These distributions produce important hysteresis transformation, showing mechanisms interaction between martensite.
