.... KEYWORDS: bainite, TRIP effect, retained austenite Introduction Free carbides bainite steel with high strength and toughness has been currently designed using models based only on the theory of phase transformation [1]. This steel follows a conventional process, and shows mechanical properties comparable...

...Paul Stratton The consensus view is that a high carbon case gives gears the best overall properties, provided that there is no carbide network and the retained austenite has been reduced below 20 % by sub-zero treatment. This view is effectively enshrined in the SAE AMS 2759/7A standard. The sub...

... in the development and processing of bearing steels. Microstructure attributes that may control the fatigue behavior are explicitly modeled in a 41xxx steel. The methodology is demonstrated by studying the role of an aluminum oxide inclusion embedded in a matrix of tempered martensite and retained austenite...

... with respect to size and shape distortion, retained austenite, and residual stress values. Testing was performed on a torque converter piston, an automotive powertrain component stamped from a sheet of 3-mm cold-worked SAE 1010 steel. A total of 53 pistons were used. While the heat treatment conditions...

... effectively. In addition, we have investigated the retained austenite and precipitation behavior of V(CN), and the evaluated rolling contact fatigue life of a heat-treated specimen. As a result, we identified that the fatigue life of developed steel samples, under contaminated lubrication environment...

... have been performed to find out new steel grades or heat treatments to cope with such severe in-service conditions. Most of these studies argued that the level of retained austenite is the main parameter which governs fatigue lifetime. The present study relates to the effect of heat treatment...

...-Hencky yield criterion and Ramberg-Osgood strain-hardening relationships are applied to describe the plastic behavior of common hardened bearing steels. A nonlinear isotropic law is applied to describe the transformation of the retained austenite during stress cycles and changes in the strain-hardening...
