The Shape Memory Effect in 50.3Mn-39.7Ni-10.0Al Alloy
Institute of Physical Metallurgy, 2nd Baumanskaya 9/23, 107005 Moscow, Russia
The shape memory effect has been observed in 50.3Mn- 39.7Ni-10.0Al alloy by thermal cycling under a load and bending at room temperature. A particular apparatus for bending tests is described. The second phase particles improve ductility of the intermetallic but result in incomplete shape recovery. Deformation of a dual phase material consisting the hard intermetallic matrix and the particles of the soft disordered phase is discussed.
