The experimental results show that electric pulse has obvious influence on the eutectic ledeburite and hard phase of the steel, lead to the change of mechanical properties. The ledeburite in the steel disappeared and the continuious boron carbide hard phase was broken into small particle, which lead to the improve of hardness and impact toughness of high-boron middle-carbon alloy. Along with the frequency increasing, the influence on the solidification microstructure and properties of the steel is more obvious. The influence is the results of the joule heating, the electromigration effect and electric magnetic effect.      ZTFLH:  分类号 TG142   基金资助:国家自然科学基金51171073和51261013资助项目。 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 44.8K 链接本文: https://www.cjmr.org/CN/      或      https://www.cjmr.org/CN/Y2013/V27/I6/605 [1] 骆宗安, 谢广明, 王光磊, 王国栋. 界面微观组织对真空轧制复合纯钛/低合金高强钢界面力学性能的影响*[J]. 材料研究学报, 2013, 27(6): 569-575.
