Fatigue behavior of Nickel alloyed permanent moulded austempered ductile

Date of Publication :19th April 2017

Abstract: Laboratory low cycle fatigue tests were conducted on permanent moulded austempered ductile iron alloyed with 1.0% and 2.0% nickel content. Samples were austenitized at 9000C for 60 minutes and austempered at 300 and 3500C for 60 to 150 minutes in steps of 30 minutes. The results indicated that PMADI samples austempered at 3000C for 60 minutes showed superior fatigue strength than other test samples. 2% Nickel PMADI samples showed better fatigue strength than 1% Nickel PMADI samples. The results were analyzed based on structure property correlation and microstructure
