Investigation into Non-Isothermal Grain Growth of Austenite Grains of Medium Carbon Steel during Heating

Key Points

• Non-isothermal grain growth of austenite occurs significantly during heating, affecting the steel's properties.
• Key evidence shows that heating leads to drastic microstructure changes, tracking grain growth across varying temperatures.
• Analysis reveals how grain growth processes in medium carbon steel respond to specific thermal treatments, importantly influencing final material strength.
• Supports the notion that better understanding of grain growth dynamics may enhance heat treatment protocols in steel production.
