Based on allotropic transformation of ingot,the definition,strength performance and feature of the iron-carbon alloy basic phase(ferrite,austenite and carburizing) are analyzed on the iron-carbon alloy phase diagram.
在铁碳合金相图上直接从工业纯铁的同素异晶转变开始分析铁碳合金基本相铁素体、奥氏体和渗碳体的定义、力学性能、特点等,再用铁碳合金基本相和相图的规律来分析铁碳合金相图的点、线和各区域组织。
It has been found that allotropic transformation of neodymium metal appears to be incomplete by X-ray diffraction analysis.
本试验表明,国产金属钕通常具有高的品位,金属钕锭宏观组织一般为三晶区,显微组织为α和β双相,x-射线衍射分析和研究表明,金属钕出现罕见的同素异晶转变不完全性,根据金属钕的布氏硬度测定值可粗略和方便地估计其碳含量。
