Subsurface microstructural changes in a cast heat resisting alloy caused by high temperature corrosion [PDF]
, 2010 A cast HP ModNb alloy (Fe–25Cr–35Ni–1Nb, wt.%) was oxidised and carburised in CO–CO2 corresponding to aC = 0.1 and pO2 = 3 1016 atm at 1080 C. Formation of an external, chromium-rich oxide scale led to depletion of this metal in a deep alloy subsurface ...

Improving the process of layerwise laser welding of metal parts by controlling residual stresses
Известия высших учебных заведений. Поволжский регион:Технические науки, 2022 Background. Layerwise laser welding of metal parts allows you to get a weld in layers. As a result of the heating of the surface, thermal stresses sharply increase, caused by a non-stationary temperature field.
