Spheroidizing is a form of heat treatment of iron-based alloys, which is done at temperatures that are slightly below the critical range and followed by a slow cooling process. The process of spheroidizing is a specific heat treatment of steels, mainly carbon steel.
heat treatments applied to steel is the spheroidized treatment, which aims to soften it to improve its cold formability, as well as its machinability. This treatment is applied to both hypoeutectoid medium carbon steels
spheroidization treatment have not been studied to date and the present work aims to deal with this subject. In this regard, the banded ferritic-pearlitic and martensitic microstructures were considered for spheroidization annealing and subsequent intercritical heat treatment of a low carbon steel. 2. Experimental details
18 kwi 2019 · Heat-treated EN353 steel exhibits enhancement in ductility, toughness, strength and hardness; internal stresses are relieved in the material. Spheroidizing of low-carbon steel is a method of prolonged heating at a temperature below the eutectoid temperature.
