A Comparative Study on the Dynamic Tensile Behavior of Nanostructured Bainitic and Quenched-Tempered Martensitic Steels

open access: yesMetals, 2018
In order to assess the dynamic tensile behavior of a newly developed three-step low-temperature-transformed bainitic microstructure, and a conventional one-step isothermal bainitic microstructure, and a quenched and tempered martensitic microstructure, a

INFLUENCE OF COOLING RATE ON THE OCORRENCE OF RETAINED AUSTENITE IN A STEEL FOR WELDING ELECTRODES [PDF]

open access: yesTecnologia em Metalurgia, Materiais e Mineração, 2015
The effect of cooling rate on the occurrence of retained austenite in a low carbon Si-Mn steel, used for welding electrodes, is measured here by combining the sectioning of Jominy test samples with the measurement of retained austenite by X-ray ...

Effect of Precursor Microstructure on Retained Austenite and Mechanical Property of Low Carbon Steels with IQ&P Treatments

open access: yesCailiao gongcheng, 2017
The microstructure, retained austenite and mechanical property of low-carbon steels with different precursor microstructures were studied by means of intercritical reheating-quenching and partitioning (IQ&P) processes. The results show that the structure

Pressure induced magnetic and magnetocaloric properties in NiCoMnSb Heusler alloy

open access: yes, 2009
The effect of pressure on the magnetic and the magnetocaloric properties around the martensitic transformation temperature in NiCoMnSb Heusler alloy has been studied. The martensitic transition temperature has significantly shifted to higher temperatures

Effect of two-step ausforming on bainite transformation and retained austenite in a medium-carbon bainitic steel

open access: yesMaterials Research Express, 2020
It is commonly accepted that single ausforming with small strain at low temperature promotes isothermal bainite transformation and leads to more retained austenite.

Advances in martensitic transformations in Cu-based shape memory alloys achieved by in situ neutron and synchrotron X-ray diffraction methods [PDF]

open access: yes, 2012
This article deals with the application of several X-ray and neutron diffraction methods to investigate the mechanics of a stress induced martensitic transformation in Cu-based shape memory alloy polycrystals. It puts experimental results obtained by two

Structure of Retained Austenite in Plain Carbon Steels [PDF]

open access: yesNature, 1947
There are many indications that retained austenite in quenched plain carbon steels should be regarded as a face-centred tetragonally distorted structure and not face-centred cubic as heretofore.

Retained Austenite Benefits or Avoidance Requires Dependable Determination

open access: yesHeat Treating Conference, 2021
Abstract Retained austenite may be helpful or detrimental to the life of heat-treated components, but it can be difficult to accurately measure in manufactured steels. Commonly used visual sample investigations are subjective and often incorrect, magnetic measurements require part-specific calibration, and electron backscattering ...
