A current goal driving alloy development is the identification of alloy compositions for high
temperature applications but with the additional requirement of sufficient ductility at ambient …

Exceptional high brittle-to-ductile transition temperature (BDTT) is a critical issue that limits
the application of tungsten as structural materials. The controlling factors in BDT have been …

We have investigated the strain-rate dependence of the brittle-to-ductile transition (BDT)
temperature in pre-cracked tungsten single-crystals and polycrystals. There is an …

This paper attempts to elucidate fundamental mechanisms of the brittle-to-ductile transition
(BDT) in textured, pre-deformed, polycrystalline body-centred cubic metals. For this purpose …

A high strength steel with a combination of∼ 930 MPa yield strength and excellent low
temperature toughness with an upper shelf energy of above 200 J and ductile brittle …

In this paper, we resolve the role of grain boundaries on toughness and the brittle-to-ductile
transition. On the one hand, grain boundaries are obstacles for dislocation glide. On the …

Here we elucidate the mechanisms of plastic deformation and fracture of tungsten laminated
composites. Our results suggest that the mechanical response of the laminates is governed …

The aim of this paper is to elucidate the mechanisms controlling the brittle-to-ductile
transition (BDT) in pre-deformed, textured, polycrystalline body-centred cubic (bcc) metals …

High‐tech ceramics are typically engineered by controlling point defects and interfaces
while one‐dimensional dislocations have found much less attention so far. Nevertheless …

Here we show that cold-rolling of tungsten (W) decreases the stable crack growth onset
temperature. Furthermore, we show that stable crack growth is accompanied by crack …
