Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving …

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 …

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

Ultrafine‐grained (UFG) refractory metals are promising materials for applications in
aerospace, microelectronics, nuclear energy, and many others under extreme environments …

Alien elemental segregation can pronouncedly change the grain boundary properties.
Systematic first-principles calculations were performed to investigate the Mg and Cu …

Ni and its alloys are susceptible to hydrogen embrittlement. In this study, we investigate the
phenomenon of hydrogen-enhanced decohesion at inter-phase interfaces in precipitation …

The inherent brittleness of the refractory metal tungsten represents a major challenge for its
application as divertor material in future nuclear fusion reactors. Grain refinement to the …

Substantial disagreement exists for segregation energies between experimentally measured
and first principles calculated values. To resolve this standing issue, we computed …

In this study we investigate Zn liquid metal embrittlement at Fe grain boundaries (GBs) by
employing ab initio density functional theory (DFT) simulations. We consider three different …

The challenge of sintering ultrafine-grained refractory metals and alloys to full density is
hereby addressed by pressureless two-step sintering in tungsten-rhenium alloy and pure …
