| Abstract: |
| The microstructure and phase transformation behaviors of Cu-8.9Al-12.4Mn-0.07B, a low temperature shape memory alloys heat treated with different conditions, are investigated. The results show that the grain size of the alloy is refined by the addition of the Boron and the precipitation of Cu9Al4 (γ2) is suppressed while ageing at room temperature. |
