A metal additive manufacturing process results in a nearly net-shaped fabrication of parts
directly from digital data. A local heat source melts the deposited material, and a part is built …

An attractive, alternative approach for the reduction of harmful residual stresses in weld
zones is reviewed, which utilises low temperature, solid-state, displacive phase …

A method for modeling the effect of stress relaxation at high temperatures during laser direct
energy deposition processes is experimentally validated for Ti-6Al-4V samples subject to …

In this study, the weld residual stresses (RS) in a 25 mm thick ferrite steel plate with newly
developed low-temperature transformation (LTT) welding wire were investigated by finite …

Electron backscattering diffraction (EBSD) was used to study a stationary shoulder friction
stir weld in Ti-6Al-4V. Weld temperatures exceeded the β-transus, resulting in a …

Constitutive plasticity theory is commonly applied to the numerical analysis of welds in one
of three ways: using an isotropic hardening model, a kinematic hardening model, or a mixed …

Three plate joints, namely, single-pass weld, double-pass weld, and four-pass weld were
fabricated using P92 steel. The hole-drilling strain-gauge method and X-ray diffraction …

Numerical finite element analyses were combined with experimental observation of a single-
pass autogenous beam weld in SA508 Gr. 3 Cl. 1 ferritic steel. Two weldment sets were …

Abstract Bulk crack-free Fe-Cr-Ni-Mo-Si-B alloy (with high hardness of 54.5 HRC) was
fabricated via laser metal deposition (LMD). The solid-state phase transformation (PT) …

To investigate the influences of phase transition temperature and preheating on the residual
stress of multi-layer and multi-pass laser metal deposition (LMD), the multi-layer and multi …
