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 …

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

The challenge of producing dense ultrafine-grained (UFG) tungsten is hereby addressed by
a simple pressureless two-step sintering method. It provides a uniform microstructure with …

Tungsten is notoriously brittle metal at room temperature. Furthermore, contrary to most
metals, plastic deformation increases ductility and recrystallization decreases ductility of …

Nanostructured materials (NsM) are typical materials with structural length scales of one,
two, or three dimensions in the range of 1–100 nm. In the development of NsM, the …

Tungsten (W) is the most commonly used high-temperature refractory metal in many critical
fields such as aerospace, military and electronic industries etc. This paper proposes a low …

Poor mechanical properties and large tungsten grains prevent the reported W-Ni 3 Al alloy
from being used as a kinetic energy penetrator (KEP). Based on our previous flaky Ni 3 Al …

In this work, several ultrafine-grained W–Cu composites were prepared by sintering at
different temperatures of 1050° C, 1150° C, 1250° C and 1350° C of 2 h followed by …

Tungsten is the plasma-facing material of choice for the divertor region in ITER as it has
favorable properties under ion irradiation. However, tungsten is a very brittle material whose …

Tungsten is a refractory metal with the highest melting point of all metals, which is
considered as a promising candidate material for plasma-facing materials in the future …
