历史和现况硼钢的开发和应用,在国外已经经历了四十多年。加硼可提高钢的淬硬性,长期以来,由于热处理性能不稳定,影响硼钢的推广使用。近年来,由于研究工作的深入,以及综合利用了化学分析、自动射线照相、透射电子显微镜、光谱仪、微区域电子探针等一类技术。冶金学家对硼在钢中作用的奥秘,在熔融的钢液中加入多少硼和用什么方法加入等,有了较好的了解。同时为了节约铬、镍、钼等昂贵的合金化金属,人们对开发和应用硼钢,重新引起了兴趣。所有这些因素,
History and Current Situation The development and application of boron steel has gone through more than 40 years in foreign countries. Boron can improve the hardenability of steel, for a long time, due to unstable heat treatment, the promotion of the use of boron steel. In recent years, due to in-depth research, and comprehensive utilization of chemical analysis, automatic radiography, transmission electron microscopy, spectroscopy, micro-area electron probe and other technologies. The mystery of metallurgists on the role of boron in steel, how much boron to add in the molten steel, and what methods to add, gives a good idea. At the same time in order to save chromium, nickel, molybdenum and other expensive alloying metals, the development and application of boron steel people, renewed interest. All of these factors,
