TL;DR: In this paper, the applicability of eddy current testing (ECT) technique to assess and quantify sensitisation and intergranular corrosion (IGC) in thermally aged AISI type 316 stainless steel was discussed.
Journal ArticleDOI
Characterization of aging behaviour in M250 grade maraging steel using eddy current non-destructive methodology
TL;DR: In this paper, the effect of aging of solution annealed M250 grade maraging steel on the microstructure, room temperature hardness and eddy current (EC) parameters was investigated.
Journal ArticleDOI
Optimisation of pulsed eddy current probe for detection of sub-surface defects in stainless steel plates
TL;DR: In this article, a model based design optimisation of PEC probe for the detection of sub-surface defects located more than 4mm from surface in a 8mm thick AISI type 316 stainless steel plate is presented.
Journal ArticleDOI
Detection of leakage magnetic flux from near-side and far-side defects in carbon steel plates using a giant magneto-resistive sensor
TL;DR: In this article, an optimized measurement system with magnetic yoke, GMR sensor and selective amplifier has been devised to detect the tangential component of leakage flux from various near-side notches and far-sides notches (widths 0.5 mm and 1.0 mm, respectively).
Journal ArticleDOI
Nondestructive assessment of tensile properties of cold worked AISI type 304 stainless steel using nonlinear ultrasonic technique
TL;DR: In this paper, a new approach based on nonlinear ultrasonic (NLU) technique is presented for nondestructive evaluation of yield strength and tensile strength of cold worked AISI type 304 stainless steel (SS).
