Journal ArticleDOI
Effects of dilution on microstructure and wear behaviour of NiCr hardface deposits
TL;DR: In this paper, the effect of dilution on the microstructure, hardness and wear properties of two nickel base NiCr hardfacing alloys deposited using the gas tungsten arc welding (GTAW) process has been studied.
Journal ArticleDOI
Delta ferrite in the weld metal of reduced activation ferritic martensitic steel
Shiju Sam,C. R. Das,V. Ramasubbu,Shaju K. Albert,A.K. Bhaduri,T. Jayakumar,E. Rajendra Kumar +6 more
TL;DR: In this article, the formation of delta(δ)-ferrite in the weld metal, during autogenous bead-on-plate welding of Reduced Activation Ferritic Martensitic (RAFM) steel using Gas Tungsten Arc Welding (GTAW) process, has been studied.
Journal ArticleDOI
Study on tempering behaviour of AISI 410 stainless steel
Gopa Chakraborty,C. R. Das,Shaju K. Albert,A.K. Bhaduri,V. Thomas Paul,G. Panneerselvam,Arup Dasgupta +6 more
TL;DR: In this paper, the authors studied the effect of tempering on martensitic stainless steels and found that temper embrittlement is highest when the steel is tempered at 823 K, whereas chromium rich carbides dominate precipitation at high temperature tempering.
Journal ArticleDOI
Finite element analysis of effect of triaxial state of stress on creep cavitation and rupture behaviour of 2.25Cr–1Mo steel
TL;DR: In this article, the effect of notch sharpness on stress distribution and damage across the notch plane was investigated by performing creep tests on plain and circumferential U-notch specimens of different notch acuity ratios ranging from 1 to 20.
Journal ArticleDOI
Study on microstructure and wear properties of different nickel base hardfacing alloys deposited on austenitic stainless steel
Gopa Chakraborty,Niranjan Kumar,C. R. Das,Shaju K. Albert,A.K. Bhaduri,Sitaram Dash,A.K. Tyagi +6 more
TL;DR: In this paper, the microstructure, hardness, and wear properties of three nickel base Ni-Cr-B-Si hardfacing alloys deposited on austenitic stainless steel by gas tungsten arc welding are evaluated by ball-ondisc tribo-test followed by electron microscopy and Raman spectroscopy of the worn out surfaces.
