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

Formation of Bainite in a Low‐Carbon Steel at Slow Cooling Rate – Experimental Observations and Thermodynamic Validation

steel research international, Volume 96, Issue 2, February 2025.
A low‐carbon (0.23 wt%) carbide‐free bainitic steel is successfully developed with a total alloying addition of 4.9 wt%, which is relatively lower than alloying additions reported in similar category of steels. The present findings indicate that the currently designed low‐alloy steel composition is amenable to generation of nearly carbide‐free bainitic

The Effect of Cryogenic Treatment on W360 and E38K Hot Work Tool Steels

steel research international, Volume 95, Issue 9, September 2024.
The cryogenic treatment facilitates the transformation of retained austenite to martensite to an undetectable limit, with about 3 times higher amount of the carbide precipitation for both steel types. Both steel types exhibit almost similar impact energy values at room temperature, but E38K steel has 2 times higher energy at 350 °C.

Determining Factors of Grain Size in Bainite Structure of Fe–2Mn–C Alloys

steel research international, Volume 95, Issue 8, August 2024.
The crystallographic variants and effective grain sizes of bainitic ferrite in Fe–2Mn–C alloys with various carbon contents are determined by local orientation measurements. Decrease in transformation temperature is beneficial for grain refinement of bainite structure although effects of carbon content are different between low‐carbon and high‐carbon ...

Effect of austempering parameters and manganese content on the machinability of austempered ductile iron produced using novel method

Cogent Engineering
Austempered ductile iron is an innovative material obtained by subjecting it to an austempering heat treatment. The wide application of this material is because its properties are comparable to those of steel, which has a much lower weight.

Erozija nodularnog lijeva česticama kvarcnog pijeska [PDF]

, 2010
Ductile cast iron has high fatigue strength due to the spherical shape of graphite, especially after quenching and tempering. Higher toughness can be achieved by austempering.
