【摘要】：采用OM、SEM、XRD等實(shí)驗(yàn)方法,對(duì)不同固溶溫度下Fe-22.8Mn-8.48Al-0.86C低密度鋼的組織演變規(guī)律和力學(xué)性能進(jìn)行了研究。結(jié)果表明,固溶處理對(duì)實(shí)驗(yàn)鋼的組織與性能影響較大,實(shí)驗(yàn)鋼晶粒尺寸隨固溶溫度的升高而增大,抗拉強(qiáng)度隨著固溶溫度的升高而降低。在1100℃固溶處理1 h后,實(shí)驗(yàn)鋼具有最佳的強(qiáng)塑性配合,抗拉強(qiáng)度為757.4 MPa,斷后伸長(zhǎng)率為68.0%,強(qiáng)塑積可達(dá)51.5 GPa·%,計(jì)算得出Fe-22.8Mn-8.48Al-0.86C鋼的密度為6.9 g/cm~3。
[Abstract]:The microstructure evolution and mechanical properties of Fe-22.8Mn-8.48Al-0.86C low density steel at different solution temperatures were studied by means of OM,SEM,XRD and other experimental methods. The results show that the effect of solution treatment on the microstructure and properties of the experimental steel is great. The grain size of the experimental steel increases with the increase of the solution temperature, and the tensile strength decreases with the increase of the solution temperature. After solution treatment at 1100 鈩，
