Nickel-based superalloys have been widely used in aerospace fields, especially for engine
hot-end parts, because of their excellent high-temperature resistance. However, they are …

This review article provides a critical assessment of the progress made in computational
modelling of metal-based additive manufacturing (AM) with emphasis on its ability to predict …

Cracking during solidification is a serious defect in castings and welds. When solidification
shrinkage and thermal contraction of the semisolid and its surrounding solid are obstructed …

Inherent micro-cracking mechanisms in two contrasting high-gamma-prime (high-γ') Ni-
based superalloys processed by laser powder bed fusion (LPBF) were investigated. RENÉ …

To achieve an effective design of additively manufacturable Ni superalloys with decent
service performance, a hybrid computational design model has been developed, where the …

Two batches of pre-alloyed Hastelloy-X powder with different Si, Mn and C contents were
used to produce specimens by Selective Laser Melting (SLM). Cracks with various …

A new criterion for the appearance of hot tears in metallic alloys is proposed. Based upon a
mass balance performed over the liquid and solid phases, it accounts for the tensile …

This review represents a comprehensive coverage of results reported in the literature over
last 50 years on the methods of studying hot tearing and mechanical properties of semi-solid …

The crack susceptibility map of a ternary Al alloy system provides useful information about
which alloy compositions are most susceptible to cracking and thus should be avoided by …

Processing of aluminum alloys by wire arc additive manufacturing (WAAM) gained
significant attention from industry and academia in the last decade. With the possibility to …
