Residual stresses are inherently introduced to forged products during their deformation. These stresses influence the integrity of load-bearing parts. Their effects depend on their nature (tensile or compressive), location and magnitude.
Often hidden beneath the skins of military aircraft, forgings were nonetheless widely used in the engines, ordnance casings and landing-gear assemblies of historic military aircraft, just as they are at the present time.

Additive-manufacturing (AM) technologies have drawn a lot of attention and investment from the manufacturing community in recent years. This article presents an overview of AM processes, including their economic and operational advantages and constraints.
Of all hardfacing applications, tool-and-die repairs are one of the most metallurgically challenging. What makes it so challenging is the metallurgy of the base materials and their compatibility with the hardfacing products, as well as the post-weld heat treatments required.
