A new austempering approach following intercritical austenitizing is explored to improve the mechanical behavior of API 5CT steel. By tailoring ferrite–bainite microstructures, the process achieves a balance of strength and ductility without the need for post‐quench tempering. The results highlight a cost‐effective alternative to conventional quenching

Effect of two-step austempering on fatigue behavior of austempered ductile iron (ADI) [PDF]
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 ...

Highsilicone Austempered Ductile Iron
Abstract Ductile iron casts with a higher silicone content were produced. The austempering process of high silicone ductile iron involving different austempering times was studied and the results presented. The results of metallographical observations and tensile strength tests were offered. The obtained results point to the fact that the silicone

Thermomechanical Processing, Microstructure, and Mechanical Properties of Medium‐Mn Steel
The microstructure evolution and mechanical properties of a medium‐Mn steel are investigated after thermomechanical processing and isothermal holding at various temperatures. A fine multiphase structure of bainite, fresh or tempered martensite, and retained austenite are obtained.

Very High Cycle Fatigue Performance of Ductile Cast Iron With Different Microstructures
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

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,
