A great deal of effort goes into production of modern steel for structural applications. The
structural integrity of the steel becomes compromised when it is welded to form engineering …

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 …

Influences of chemical dilution and the number of weld layers on residual stresses in a multi-
pass low-transformation-temperature (LTT) weld were investigated by finite element …

Finite element analysis is commonly used to investigate the thermal-mechanical
phenomena during welding. To improve the computing efficiency of finite element analysis …

This work aimed to develop a microstructure-predicting methodology (MPM) using coupled
physical-FEM-thermodynamic simulation to predict the influence of cooling time from 800 to …

Despite the fact that the additive manufacturing (AM) technique has been established for
almost two decades, its optimisation is still performed by trial and error experimentation. In …

Increasing the welding interpass temperature (IT) can reduce the welding time and cost of
welding but may degrade the quality of the welded joint. The objective of the present study …

A three-pass groove weld made by gas-tungsten arc welding in a 20-mm thick SA508 steel
plate is modeled to predict the thermal, metallurgical, and mechanical behavior. The dilution …

This study performed computational fluid dynamics (CFD) simulation to investigate the flow
patterns of molten pool during welding with a transient heat transfer. The influence of gravity …
