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.

A Statistical Review of Hydrogen Effects on the Fatigue and Fracture Behavior of Steel

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 9, Page 3613-3644, September 2025.
ABSTRACT This study conducts a statistical re‐analysis of experimental data from the literature to assess the influence of hydrogen on key mechanical properties, including the medium‐/high‐cycle fatigue strength and the threshold value of the stress intensity factor range.

Diffraction‐based determination of single‐crystal elastic constants of polycrystalline titanium alloys

open access: yesJournal of Applied Crystallography, Volume 52, Issue 5, Page 1144-1156, October 2019., 2019
The single‐crystal elastic constants of polycrystalline titanium alloys have been determined using neutron and synchrotron powder diffraction.Single‐crystal elastic constants have been derived by lattice strain measurements using neutron diffraction on polycrystalline Ti‐6Al‐4V, Ti‐6Al‐2Sn‐4Zr‐6Mo and Ti‐3Al‐8V‐6Cr‐4Zr‐4Mo alloy samples.

Effect of refined multi-scale microstructures on the ultra-high impact toughness of bainitic steel austempered below Ms temperature

open access: yesJournal of Materials Research and Technology, 2023
In this study, the multi-scale microstructures of bainitic steel were refined to different degrees by austempering below Ms (martensite start temperature). The influence of multi-scale microstructures and their boundaries on impact toughness was analyzed.

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

Ameliorated Austenite Carbon Content Control in Austempered Ductile Irons by Support Vector Regression

open access: yesMathematical Problems in Engineering, Volume 2013, Issue 1, 2013., 2013
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,

Effect of alloying elements on austempered ductile iron (ADI) properties and its process: Review [PDF]

open access: yesChina Foundry, 2015
Austempered ductile iron (ADI) parts have a unique combination of high strength and toughness with excellent design flexibility and low cost. These excellent properties are directly related to its microstructure called "ausferrite" that is the result of ...

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

Multiphase Ausformed Austempered Ductile Iron [PDF]

open access: yesArchives of Metallurgy and Materials, 2017
AbstractDuctile iron was subjected to a total true strain (φt) of 0.3 either by applying φtin the austenite region or by apportioning it through applying a true strain of 0.2 in the austenite region before quenching to austempering temperature (TA) of 375°C, where a true strain of 0.1 is applied (ausforming).
