Abstract
- The effects of different forming process on the microstructure, martensitic transformation, and mechanical properties of the Ni<subscript>50</subscript>Mn<subscript>34</subscript>In<subscript>14</subscript>Co<subscript>2</subscript> (numbers indicate at.%) alloys were investigated in detail. The results show that the microstructure of Ni<subscript>50</subscript>Mn<subscript>34</subscript>In<subscript>14</subscript>Co<subscript>2</subscript> alloy consists of the matrix and the second phase by powder hot forging technology under the forces in different directions and spark plasma sintering (SPS), and the prepared sample has obvious preferred orientation by applied force in the three directions. The grain and the second phase of prepared sample were obviously refined by the hot forging technology. The martensitic transformation behavior was almost unchanged by different forming process. In addition, the shape memory effect of prepared Ni<subscript>50</subscript>Mn<subscript>34</subscript>In<subscript>14</subscript>Co<subscript>2</subscript> alloy was significantly enhanced by different forming processes.
