Quenching requires precise and rapid cooling. After tempering, this process, creates hard steel that can withstand extreme applications. This course discusses the new generation of high-pressure gas-quenching system (HPGQ) as well as the efficiency of oil systems and commercialization of water-quenching techniques.

Intensive Quenching Process Commercialization
An intensive water-quenching process was originated by Dr. Nikolai Kobasko of the Ukraine in early 1960s. Intensive quenching (IQ) methods and their practical applications are presented in numerous technical papers, conference proceedings and books. This article looks at the IQ method in comparison to traditional quenching.

Technology Evolution of the Integral-Quench Furnace
Over the years, the heat-treatment industry has seen a number of truly innovative technology advancements – the oxygen probe and the adaptation of process simulators for recipe development being perhaps the most impactful to date. Now the heat-treat world is seeing another groundbreaking technological advancement, the introduction of the next generation of integral-quench furnaces.

Case Hardening Under Vacuum with Oil Quenching
Vacuum heat treating encompasses a wide variety of processes. Case hardening is just one of them. Examples include carbonitriding and carburizing. By diffusing carbon into the part surface, followed by quenching of the part, a hard and wear-resistant surface is formed while maintaining a ductile core. This article looks at vacuum furnace case hardening utilizing oil quenching.

Understanding the Jominy End-Quench Test
The Jominy end-quench test is the standard method for measuring the hardenability of steels. This article considers the basic concepts of hardenability and discusses the ability of the steel to be hardened in depth by quenching.
