本文应用余瑞璜的“固体与分子经验电子理论”对60、60Mn、60Si_2Mn钢马氏体的价电子结构进行了键距差(BLD)分析。60钢马氏体可视为由不含碳阵胞和含碳阵胞混乱堆积构成,含碳阵胞的n_A值为0.9783;60Mn钢马氏体可视为由不含碳阵胞、含碳阵胞和含碳、锰阵胞混乱堆砌构成,含碳、锰阵胞的n_A值为1.0316;60Si_2Mn钢马氏体可视为由不含碳阵胞、含碳阵胞、含碳、硅阵胞、含碳、锰阵胞和含碳、锰、硅阵胞混乱分布构成,含碳、硅阵胞的n_A值为1.3283,含碳、锰、硅阵胞的n_A值为1.3097。将上述阵胞中的n_A值进行比较,可立即看出含硅合金钢具有高的弹性极限、屈服极限和高的回火稳定性的原因。
In this paper, the valence electron structure of 60,60Mn, 60Si_2Mn martensitic steel was analyzed by the Bond Distance Difference (BLD) using the “Solid and Molecular Experience Electronic Theory” by Yu Ruihuang. 60 martensitic steel can be considered as a non-carbon-based array of cells and the formation of chaos containing carbon array composed of carbon array n_A value of 0.9783; 60Mn martensitic steel can be considered to be free of carbon array cells containing carbon Arrays and carbon-containing, manganese array formation confusion, carbon, manganese array cells n_A value of 1.0316; 60Si_2Mn martensitic steel can be considered to be free of carbon array cells, carbon array, carbon, silicon array The results showed that the n_A value of carbon, silicon matrix cells was 1.3283, and the n_A value of carbon, manganese and silicon matrix cells was 1.3097. Comparing the n_A values in the above array cells, one can immediately see the reason why the silicon-containing alloy steel has high elastic limit, yield limit and high tempering stability.
