MetalMat, Volume 3, Issue 2, June 2026.ABSTRACT Machining of materials is an invaluable technique to give specific shapes and dimensions of desired materials. Different machining processes give rise to different surface characteristics that include not only surface roughness but also specific surface morphology, such as the recast layer.

steel research international, Volume 97, Issue 6, Page 3267-3281, June 2026.Laser welding of duplex stainless steel disrupts phase balance, promotes nitride precipitation, and reduces fatigue resistance. Postweld heat treatment restores austenite and dissolves nitrides, but the resulting crystallography and phase morphology still impair fatigue performance.
