The Decarburization Mechanism in Rimming Steel

Measurement of Decarburization of Heat Treated Steel Surfaces

Decarburization is a significant problem in the heat treatment of steels as decarburization is detrimental to wear life and fatigue life of components. This presentation concentrates on its measurement by four procedures. Test results from an interlaboratory test of steels with spheroidize annealed, lamellar pearlite (normalized) and quenched and tempered martensitic microstructures were evalua...

Multilayer perceptron to model the decarburization process in stainless steel production

The Argon-Oxygen Decarburization (AOD) is the refining process of stainless steel to get its final chemical composition through several stages, where tons of materials are added and oxygen and inert gas are blown. The decarburization efficiency and the final temperature in each stage are two important values of this process. We present in this paper an empirical model, based on Multilayer Perce...

Effects of Temperature and Oxygen Concentration on the Characteristics of Decarburization of 55SiCr Spring Steel

Effects of temperature and oxygen concentration on decarburization of 55SiCr spring steel were investigated at the temperature range of 500°C–1 200°C by using a Muffle furnace (an atmosphere of ambient air) and a Simultaneous Thermal Analyzer (low oxygen concentration with 2% O2 and 98% N2). In ambient air, the decarburization behavior can be divided roughly into five temperature ranges: T≥1 20...
