Effect of two-step austempering on fatigue behavior of austempered ductile iron (ADI) [PDF]
SN Applied Sciences, 2019 The effect of two-step austempering on the fatigue properties in alloyed ductile iron was studied. The ductile irons were subjected to conventional and two-step austempering processes. The austempering process was performed by making three batches. In the first batch, samples after austenitizing at 900 °C were conventionally austempered separately at ...
