The effect of reducing the austempering time on the fatigue properties of austempered ductile iron
Materials Science and Engineering: A, 2012Abstract The effect of reducing the austempering time on the high-cycle fatigue behavior of austempered ductile iron (ADI) has been investigated by subjecting samples to rotating bending and fatigue crack propagation tests. Starting from the same cast iron, two distinct types of ADI were austempered at the same temperature of 360 °C but for different

Abstract Martempering and austempering processes may eliminate the need for conventional oil quenching and tempering. This article presents the suitability of steels for martempering and austempering. It discusses the compositions of oils suitable for marquenching and modified marquenching and also presents safety precautions recommended

Abstract Austempered ductile iron (ADI) has found enormous applications in recent years due to its high strength and hardness, coupled with substantial ductility and toughness. The high strength and hardness of ADI have caused many researchers and engineers to doubt the machinability of this material.

Abstract AUSTEMPERED DUCTILE IRON has high strength with excellent toughness and ductility. Its strength is twice that of conventional ductile irons, comparable to heat-treated wrought steels. Composition is balanced to provide foundry compatibility, minimal segregation and good response to austempering.

Tensile properties of copper alloyed austempered ductile iron: Effect of austempering parameters
Journal of Materials Engineering and Performance, 2004A ductile iron containing 0.6% copper as the main alloying element was austenitized at 850 °C for 120 min and was subsequently austempered for 60 min at austempering temperatures of 270, 330, and 380 °C. The samples were also austempered at 330 °C for austempering times of 30–150 min.

Mechanical Characterization of Austempered Ductile Iron Obtained by Two Step Austempering Process
Transactions of the Indian Institute of Metals, 2017Austempered ductile iron (ADI) is known to have a good combination of mechanical properties due its unique ausferrite microstructure. The strength of ADI is mainly a function of the austempering temperature and the stability of ausferrite matrix. To increase the stability of the ausferritic matrix, two stage austempering processes was developed. During

Improvement in fracture toughness of austempered ductile iron by two-step austempering process
International Journal of Cast Metals Research, 2010Abstract Ductile cast iron samples were austenitised at 900°C and subjected to two types of austempering called as conventional austempering and two-step austempering. Five different temperatures, 280, 300, 320, 350, 380 and 400°C, with an austempering time of 2 h, were chosen for conventional austempering.
