| 摘 要： | The change of microstructure with strain was investigated in a Fe-32Mn-5Si austenitic alloy at room temperature by X-ray diffraction profile analysis. The experimental results show that the Fe-32Mn-5Si alloy is deformed by the strain-induced γ→ε transformation and the twinning except dislocation slip at room temperature. The amount of strain-induced ε-martensite, the stacking fault probability and the twinning probability all exhibit parabolic relationship with increasing strain. The stacking fault probability is higher than the twinning probability.

| Abstract: | T he change of microstructure with strain was investigated in a Fe-32Mn-5Si austenitic alloy at room temperature by X-raydiffraction profile analysis. The experimental results show that the Fe-32Mn-5Si alloy is deformed by the strain-induced γ→εtransformation and the twinning except dislocation slip at room temperature. The amount of strain-induced ε-martensite, thestacking fault probability and the twinning probability all exhibit parabolic relationship with increasing strain. The stackingfault probability is higher than the twinning probability. |
