The current study reports the analysis of the deformation mechanisms at 600° C in a two-
phase, BCC+ B2, refractory complex concentrated alloy (RCCA) Al 0.5 NbTa 0.8 Ti 1.5 V 0.2 …

Microscopic defects and their mutual interactions are fundamentally important in deciding
the load carrying capacity of structural materials. In this context, the present work reports an …

In this study, submicron-WC reinforced Inconel 718 composites were fabricated by selective
laser melting (SLM). They were investigated regarding forming quality, microstructure …

Heterogeneous precipitation and hence the distribution of α and β phase in α+ β titanium
alloys can impact strongly on alloy mechanical properties. The β phase is commonly …

Additively manufactured (AM) alloys present unique and heterogeneous microstructures due
to the complex, highly dynamic laser-material interactions. These AM-inherent …

Nickel (Ni)-based superalloys are used for safety-critical components in the aerospace
industry because of their high strength at elevated temperatures. These materials are …

With the aim of understanding the effect of creep defects in the γ′ phase on the creep
resistance, the atomic structure and elemental segregation behavior of stacking faults (SFs) …

Almost 75 years of research has been devoted to producing superalloys capable of higher
operating temperatures in jet turbine engines, and there is an ongoing need to increase …
