In this study, austenite formation from hot-rolled (HR) and cold-rolled (CR) ferrite-pearlite structures in a plain low-carbon steel was investigated using dilation data and microstructural analysis. Different stages of microstructural evolution during heating of the HR and CR samples were ...
An experiment is performed for explosive convergence (collapse) of a cylindrical shell of low carbon steel with a ferrite-perlite structure. It is revealed that during ultra-rapid heating caused by high-speed deformation austenite formation occurs in an unusual sequence: first, free ferrite is ...

Although high carbon martensitic steels are well known for their industrial utility in high abrasion and extreme operating environments, due to their hardness and strength, the compressive stability of their retained austenite, and the implications for the steels' performance and potential uses, is not...
[translate] aModeling non-isothermal austenite formation in low carbon steel 在低碳钢塑造非等温奥氏体形成[translate]
A granular pearlite structure in steel may be obtained directly from homogeneous austenite during isothermal decomposition after previously thermally cycling it at temperatures of the subcritical region. During thermal cycling, alternating thermal stresses of considerable absolute value arise in austenite, and...
amounts of iron in them. This is because the face-centered cubic arrangement of its atoms is not magnetic, unlike the body-centered cubic structure that ferrite has. The face-centered cubic structure of austenite also allows it to hold higher amounts of carbon than other steel crystal ...
Austeniteis not a commonly occurring microstructure in lowcarbon steelat room temperature. However, it may appear in special, highstrength,carbon steelsand in dual-phase steels (Figure 3.15).18The presence of anaustenite phaseimproves ductility. ...
making use of transformation induced plasticity due to retained austenite, a 0·lC5Mn (wt-%) steel was examined to ascertain whether a considerable amount of retained austenite is formed after simple thermal treatment consisting of heating, holding at temperatures in the intercritical range, and cool...
