the present article considers the nd:yag pulsed laser welding of 304 stainless steels with two different compositions. the effects of various laser operational parameters and cooling rates on the weld microstructures were considered. the results show that ferritic solidification is produced in the stainless steel with the creq/nieq ratio of 1.7, and austenitic solidification is produced in the ...

During ageing, the ferritic phase of Cast Austenitic Stainless Steels (CASS) undergoes decomposition by spinodal and G-phase precipitation, which leads to increasing hardness decreasing impact toughness. Mo-bearing steels are more prone ageing than Mo-free steels. To study effects Ni, Mo, Mn, duplex model alloys were thermally aged at 350 °C 400 °C. The microstructure evolution during was chara...

Defect-free welds between A-516 ferritic and 316L austenitic stainless steel were achieved using inertia friction welding (IFW) under varying forge pressures. The microstructural evolution the associated mechanical properties characterised across different weld regimes. free from microcracks demonstrated higher strength hardness than parent metal (PM), indicating enhanced properties. Carbide pr...

Susceptibility of three lean-alloyed ferritic-austenitic stainless steels to hydrogen-induced delayed cracking was examined, concentrating on internal hydrogen contained in the materials after production operations. The aim was to study the role of strain-induced austenite to martensite transformation in the delayed cracking susceptibility. According to the conducted deep drawing tests and cons...
