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 Cooling Rate on Bainite Phase Formation in Austempered Nickel‐Molybdenum Gray Cast Iron

International Scholarly Research Notices, Volume 2011, Issue 1, 2011., 2011
Taking into account the importance of the amount of bainite phase on the microstructure of cast irons and its influence on the improvement of mechanical properties, this research selected an alloy of gray cast iron containing Nickel‐Molybdenum and conducted the austenitising and austempering processes at 900°C and 400°C for 60 minutes, respectively ...

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.

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.
