Modeling and studying of the effect of part geometry and grain size in heat treatment of 1050 steel using AC3 software

In this article, the effect of the work piece geometry and microstructure grain size on the heat treatment of 1050 steel has been investigated. For this purpose, two samples of work pieces with round (cylindrical) and square (flat) sections were considered for simulation with AC3 software. The effect of each of them was investigated on the growth of grain size in different cooling environments. Also, the hardness at the surface and depth was evaluated for both conditions. The results of the simulation show that the used software has a suitable ability to predict surface and depth hardness, grain size and the behavior of CCT parameters and cooling curves in the heat treatment of 1050 steel and this method can be used on a workshop scale and to be used in industrial applications.
