WebThe solid-state phase transformation modifies microstructure and improves both physical and mechanical properties. The driving force of the solid-state phase transformations originate from the atomic level electronic transfer between d-electrons and s-band [4]. Studies have analysed phase transformation and microstructure using 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. WebFeb 22, 2024 · Steel is the most important alloy for engineering applications.
