摘要
根据"余氏理论",建立了一元合金Mn、Cr元素在含0.4%C马氏体中的价电子结构,研究了马氏体价电子结构与回火转变的关系,通过对热处理后的试样所进行的透射电镜及能谱分析,印证了"固相合金中C-Me偏聚理论,从而在固溶态价电子理论的深度揭示了合金元素在马氏体中的力学行为.
Based on Yu's theory,the valence electron structures of martensite of single alloy element Mn and Cr in 0.4%C was established.The relation between the valence electron structure of martensite and the temper transformation was researched.By TEM and energy spectral analysis,'C-Me SEGREGATION THEORY IN SOLID SOLUTION' was proved,and from the depth of the valence electron theory in solid solution,the mechanics behaviour of the alloying element in martensite was shown.
