| Summary: | Заглавие с экрана The effect of mechanical trainings (loading/unloading under constant temperature and cooling/heating under applied stress) on two-way shape memory in [001]-oriented Ni49Fe18Ga27Co6 (at. %) single crystals was investigated. It was experimentally shown, that in single crystals after the stress-induced aging at 1373 K, 25min. + 673 K, 4 h followed by the training (cooling/heating at constant applied stress 80 MPa), the two-way shape memory effect with the maximum strain of 4.5 % is realizes. Its value is greater on 3,0 % in comparison with the single crystals after the stress-free aging at 1373 K, 25min. + 673 K, 4 h. The 100 cycles of loading/unloading training at room temperature in comparison with the isobaric training leads to the increase of both reversible strain on 0.5-1.0 % and thermal hysteresis in aged single crystals. |
