One of the most dangerous technical failures of materials is intergranular brittle fracture
(temper embrittlement) as it proceeds very quickly and its appearance is often hardly …

In this work, processing of molybdenum and tungsten by Selective Laser Melting (SLM) is
analyzed. The study reveals the impact of the oxygen content of the powder, the process …

Body-centered cubic refractory metallic materials exhibit excellent high-temperature
strength, but often suffer from brittle intergranular fracture due to the recrystallization-induced …

The formation mechanism of twin boundaries in transition metal nitrides has remained
largely unexplored owing to their high stacking fault energy that hinders twin boundary …

First-principles calculations of the Σ 5 (310)[001] symmetric tilt grain boundary in Cu with Bi,
Na, and Ag substitutional impurities provide evidence that in the phenomenon of Bi …

We investigate grain boundaries (GBs) in W–25 at.% Re alloys with special focus on the
segregation of Re to the GBs and the changes in their cohesive properties that arise …

Molybdenum (Mo) alloys with different La 2 O 3 particle additions (0.6, 0.9, 1.5 wt.%) were
prepared by powder metallurgy to investigate the effect of La 2 O 3 particles on …

Elemental segregation can pronouncedly affect the cohesion of grain boundary (GB), which
shows tremendous potential in altering the thermal stability and mechanical properties of …

Most research on nanocrystalline alloys has been focused on planned doping of metals with
other metallic elements, but nonmetallic impurities are also prevalent in the real world. In this …

Impurities are often driven to segregate to grain boundaries, which can significantly alter a
material's thermal stability and mechanical behavior. To provide a comprehensive picture of …
