Eutectoid reaction中文
WebAbstract. Eutectoid and peritectoid transformations are classified as solid-state invariant transformations. This article focuses primarily on the structures from eutectoid transformations with emphasis on the classic iron-carbon system of steel. It reviews peritectoid phase equilibria that are very common in several binary systems. Web朱祖昌，杨弋涛，朱闻炜 (1.上海工程技术大学，上海 201620； 2.上海大学，上海 200072；3.上海轨道交通检测认证(集团)有限公司，上海 200434)
