前言钢铁中加入0.01%以下的硼,对其机械性能的改进却极有助益。如:提高钢的淬透性;改善变形性;可加工性等。所以,近十余年来人们对于用硼代替 Mn、Ni、Cr、Mo 及其他元素有了很大的注意。现在硼钢成为各国钢铁工业发展的重要方向之一。我国硼钢的生产,亦有很大的进展。因此,对高硼钢及硼铁中硼的测定,找出一个既快又准的分析方法,也愈趋迫切。钢铁研究院分析室所述方法,手绩繁,
Preface Adding 0.01% or less of boron to steel improves the mechanical properties greatly. Such as: to improve the hardenability of steel; to improve the deformation; processability and so on. Therefore, for more than ten years, people have paid great attention to using boron instead of Mn, Ni, Cr, Mo and other elements. Now boron steel has become one of the important directions for the development of the steel industry in various countries. China’s boron steel production, there have been great progress. Therefore, the determination of high boron steel and boron in ferroboron, to find a fast and accurate analytical methods, but also increasingly urgent.
