As grain size increases, the amount of ε martensite forming on cooling increases. However, with a decrease in grain size, more ε is induced by deformation, improving shape memory effect. 한국열처리공학회 Fe-Mn계 합금에서 응력유기 ε 마르텐 사이트의 양에 미치는 열처리 온도의 영향 Effect of Heat Treatment Temperature on Amount of Stress-Induced ε Martensite in an Fe-Mn Baesd Alloy Article 2 열처리공학회지, v.17, no.6, pp.342 - 345 열처리공학회지 17 6 342 345 kci other ART001190741 Fe-Mn based alloy Volume fraction of ε martensite Endothermic heat Grain size Shape memory effect Fe-Mn based alloy Volume fraction of ε martensite Endothermic heat Grain size Shape memory effect
