  • 초록
    • A study was undertaken to investigate the effect of cooling rate, deformation temperature and thermomehanical treatment on shape memory capacity in an Fe-12Mn-10Cr-8Ni-6Si(wt.%) alloy. Among the several specimens which were cooled at different cooling rate from the single γ phase region, water quenched specimens showed the best shape memory effect, presumably due to the high amount of stacking fault and the lack of thermally induced martensite plates. The amount of shape recovery increased with decreasing deformation temperature for all the cooling conditions. When the deformation temperature range was near the Ms temperature (about 77K), shape recovery capacity was good regardless of cooling paths. In addition, a thermomechanical treatment (4% prestrain followed by annealing at 873K for 1 hr) on water quenched specimens was found to enhance ultimate tensile strength, yield strength and shape memory capacity compared to those of water quenched specimens. The improvement of shape memory capacity of thermomechanically treated specimens seemed to be attributed to the increase in yield strength and the shift of M_d temperature from 320K to 400K.
