前言钢中的气体一直受到人们的注意。作为一个附件,本文概述对于铁合金中气体所做的研究工作。本论述将只限于氢气、氮气以及主要的合金元素 Cr、Mn、Si。各种气体和金属之间的交互作用是复杂的。气体与金属可形成固溶体,它们也可组成化合物。动力学因素可以阻碍气体和金属之间达到平衡。尽管如此,在许多条件下达到了平衡,因而气体-金属间的平衡为本文研究提供了依据。 The gas in steel has always been the subject of attention. As an annex, this article summarizes the work done on gases in ferroalloys. This discussion will be confined to hydrogen, nitrogen and alloying elements Cr, Mn, Si. The interaction between various gases and metals is complicated. Gases and metals can form solid solutions, and they can also form compounds. Kinetic factors can hinder the balance between gas and metal. In spite of this, equilibrium has been achieved under many conditions, so the gas-metal balance provides the basis for this study.
