Required microstructural attributes of an alloy vary with structural applications. The fine-tuning capability laser-powder bed fusion (L-PBF) additive manufacturing (AM) enables application specific manufacture the components. Such L-PBF AM requires alloys that exhibit wide processing window and are amenable to multiple deformation mechanisms. However, high hot cracking susceptibility Al poses ...

Cracking of nickel superalloys with a high content γ’-phase remains an unresolved problem, including in technologies for repairing gas turbine engines blades. Laser cladding is method material deposition used to repair parts exposed aggressive environment and surface wear. Cladding parameters have influence on cracking susceptibility superalloys. Alloy ZhS32 has propensity hot when laser radiat...

Low-density steels are considered an attractive potential replacement for conventional steel in industries such as the automotive sector. However, there are several issues that need to be overcome before they become commercially useful grades. A significant constraint is in their processability, for example, a large as-cast grain size means these steels are prone to hot cracking. This paper exp...
