Publication date: 15 May 2019
Abstract:
In nondestructive evaluation -NDE- of heat-treated steels, different variables of the heat treating process have complex effects on outputs of NDE methods, and hence, the effect of one desired variable on NDE outputs should be evaluated to help interpreting the changes. Read more
Journal: Nondestructive Testing and Evaluation
Publication date: 27 Feb 2019
Abstract:
It is accepted that work-hardening of Hadfield steels during plastic deformation results in the formation of mechanical twinning, which, in turn, varies the mechanical properties up to a certain depth below the surface. Read more

Publication date: 22 March 2018
Abstract:
The aim of this paper is to introduce a novel methodology for nondestructive determination of microstructural and mechanical properties (due to the various heat treatments), as well as thickness variations (as a result of corrosion effect) of dual phase steels. Read more

Publication date: 30 September 2017
Abstract:
High-strength bainitic cast iron is studied after isothermal hardening at 340°C for from 0.5 to 5 h with the use of a non-destructive eddy-current method for monitoring the microstructure and mechanical properties. Read more

Publication date: 6 March 2017
Abstract:
Austenitizing and tempering temperatures are the effective characteristics in heat treating process of AISI D2 tool steel. Therefore, controlling them enables the heat treatment process to be designed more accurately which results in more balanced mechanical properties. Read more
Journal: IEEE Transactions on Magnetics
Publication date: 30 April 2015
Abstract:
In the past decade, nondestructive electromagnetic techniques have been extensively used for the characterization of materials. In this paper, the relation between the microstructural/mechanical characteristics of D2 tool steel with magnetic and electrical properties and eddy current (EC) test outputs has been established.
