... in the expansion occurring in service. The influence of a few heat treatment parameters on retained austenite content was also briefly discussed based on the literature. Very few publications are available in the literature regarding the influence of heat treatment parameters on dimensional stability...

... The thermal effect is the most considered parameter affecting the dimensional stability of a bearing component. It is generally associated with the transformations of the metastable phases in the steel upon exposure to the operating temperature over a long period of time in service. In reality...

... that critically evaluates the ASTM C 1289-02 specification requirements for the ISO on three engineering properties: (1) dimensional stability, (2) thermal resistance, and (3) compressive strength. Preliminary results from this study reveal many unknown phenomena, particularly regarding the dimensional stability...

... The effect of processing and machining on the dimensional stability of polychlorotrifluoroethylene (PCTFE) rod stock and oxygen gas cylinder valve seats was investigated. Initial testing focused on two types of extruded rod stock and one type of compression-molded rod stock made from the same...

... to determine the best balance between materials with good dimensional stability as well as good fatigue resistance. Axial strain-controlled monotonic and fatigue test results for different treatments of 4320 steel, both carburized and plain, tested at temperatures from -40°C to 255°C are discussed. Upon...

..., endurance life or wear resistance, or both, are the decisive parameters. Through-hardened and case-hardened tapered roller bearings perform equally well in such applications, provided the requirements on hardness, microstructure, and surface integrity are fulfilled. If high-dimensional stability...
