Abstract: | NiMn alloys alloyed with aluminum in a wide range of temperatures and compositions have been investigated by resistivity measurements, electron diffraction, and X-ray diffraction. It is found that the martensitic transformation temperature decreases with an increase in the aluminum content in an alloy. The martensitic transformation temperatures were determined and the full diagram of martensitic transformations for Ni-Mn-Al alloys was constructed. It is established that alloying with aluminum leads to a change in the type of the martensite crystal structure. |
