摘要
研究了回火温度和时间对两种成分Fe-Mn基合金剪切模量的影响。结果指出,附加Cr,Ti的合金在回火状态下ΔG G-T曲线有极小和极大两个极值,而附加Cr,Ni,W,C的合金只呈现极大值特征。这是由于Ni,W,C降低反铁磁转变点T_N造成的, 随着回火温度升高或回火时间增加,ΔG_λ效应逐渐增加。
The plot of relative change of shear modulus vs temperature for as-
tempered Fe-Mn base alloy containing Cr and Ti reveals a minimum and a maxi-
mum, while for the alloy containing Cr, Ni, W and C, a maximum only. These seem
due to that the alloying elements Ni, W and C decrease the transition point of an-
timagnetization. The change of shear modulus resulted from mechanical linear mag-
netostriction may be gradually increased with the increase of tempering temperature
or the prolongation of tempering time.
