...Shekhar Srivastava; Rajiv Kumar Garg; Anish Sachdeva; Vishal S. Sharma Accumulated heat input during layer deposition causes high residual stress in the Wire-Arc Additive Manufacturing (WAAM) components. The developed residual stress results in defects like distortion, delamination, cracks, and low...

... analysis. Boriding on as-received titanium articles resulted in shape distortion that hampered the subsequent polishing efforts. Hence, further articles were treated with stress-relief annealing prior to boriding, at temperatures below and above the β -transus of the substrate article. Annealing itself...
