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

open access: yesFatigue &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

Effect of Austempering and Martempering on the Properties of AISI 52100 Steel

open access: yesInternational Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013
The mechanical properties of steel decide its applicability for a particular condition. Heat treatment processes are commonly used to enhance the required properties of steel. The present work aims at experimentally investigating the effect of austempering and martempering on AISI 52100 steel. Different tests like microstructure analysis, hardness test,

Erozija nodularnog lijeva česticama kvarcnog pijeska [PDF]

open access: yes, 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.

Sliding wear behavior of PVD CrN and TiN coated austempered ductile iron [PDF]

open access: yes, 2014
This work studies the sliding wear behavior of PVD coated austempered ductile iron samples. The effects of the substrate surface finishing method (grinding and polishing) and coating material (CrN and TiN) on the wear behavior are evaluated.

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

open access: yessteel 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

open access: yesInternational 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 ...
