在这一讲里,我们要讲普通钢中纵裂的形成原因及其规律性,以及它的分析和预防方法等问题. 1 概况纵裂是最常见的淬裂类型之一,也是人们发现最早、研究得比较深入的一种淬火裂纹.世界上研究纵裂问题最早的是H.Scott.他在本世纪的20年代中期,便提出淬透的小件容易形成纵裂的论断,而且提出了淬 In this talk, we will talk about the formation and regularity of longitudinal cracks in ordinary steel, as well as its analysis and prevention methods, etc. 1 Overview Longitudinal rupture is one of the most common types of quenching and cracking and one of the earliest , A more in-depth study of quenching cracks in the world to study the problem of vertical splitting is H. Scott.He in the mid-1920s, he proposed the possibility of longitudinal cracking of small pieces of hardenable conclusion, and proposed Quench
