Microstructural Changes during Vacuum Carburizing of Steels [PDF]
Practical Metallography, 2011 Abstract Vacuum carburizing is a modern, very efficient and environmentally friendly process for case hardening of steels. Nowadays the technology has replaced atmosphere carburizing in many cases due to better repeatability and uniformity of heat treated samples.
