Transformation from austenite in alloy steels

Phase transformations contributing to the properties of modern steels

“…The old idea of interphase precipitation [92][93][94], in which fine particles precipitate in rows parallel to the ferrite-austenite interface, has recently been revived [94. 95].…”

A phase-field model for interphase precipitation in V-micro-alloyed structural steels

“…[3]. Interphase precipitation consists of periodic rows of carbide precipitates which form si-10 multaneously at the interphase boundary between the decomposing austenite and growing ferrite [4]. Desired mechanical properties are achieved by controlling the spacing between the rows and spacing between the particles within a row.…”

“…The process is for the most part associated with a step mechanism of a/c interface motion, the particles precipitating on the stationary, immobile component of the interface 96 because the steps themselves move too rapidly to allow successful nuclei to develop. 99,100 So the idea of interphase precipitation has been around for four decades but, remarkably, it has just seen a new avatar. 101,102 This is in the context of high strength, low alloy steels used in structural applications with a yield strength in the range 400-500 MPa.…”
