Mathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013 Austempered ductile iron has emerged as a notable material in several engineering fields, including marine applications. The initial austenite carbon content after austenization transform but before austempering process for generating bainite matrix proved critical in controlling the resulted microstructure and thus mechanical properties. In this paper,

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3950-3966, September 2025.ABSTRACT The very high cycle fatigue performance of four ductile cast irons, a solid solution strengthened ferritic, ferritic‐pearlitic, and two austempered ductile cast irons, was investigated by ultrasonic fatigue testing under fully reversed loading conditions. The step‐stress fatigue testing method incorporating re‐use of runouts was employed, with

Effect of Austempering and Martempering on the Properties of AISI 52100 Steel
International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 The mechanical properties of steel decide its applicability for a particular condition. Heat treatment processes are commonly used to enhance the required properties of steel. The present work aims at experimentally investigating the effect of austempering and martempering on AISI 52100 steel. Different tests like microstructure analysis, hardness test,
