The research into rapid carbide spheroidisation aims to significantly shorten selected heat treatment processes.
Key words: accelerated spheroidisation, pearlite, globular carbide, 100Cr6 bearing steel, soft annealing
Carbide spheroidisation is a significant metallurgical process which contributes to general changes in microstructure during annealing processes (Nam & Bae, 1999).
The heat treatment process was designed to promote accelerated carbide spheroidisation leading to reduced hardness of the material.
Current processes leading to carbide spheroidisation rely on diffusion of carbon in a steel heated to a temperature close to or lightly below [A.
In order to explore the impact of introduced strain on carbide spheroidisation, thermomechanical treatment with subsequent conventional furnace annealing was carried out.
The conventionally treated specimen R1 underwent partial carbide spheroidisation throughout the volume upon 12-hour soaking at 710[degrees]C .
