Scientists at Tomsk Polytechnic University have found out how to improve the properties of new high–entropy (containing at ...

The preparation of dense Si 3 N 4-based ceramics has attracted great attention due to the achievable improvements in mechanical properties and high-temperature oxidation resistance. In general ...

At high temperatures or under stress, these devices can experience markedly more oxidation because of their large surface area-to-volume ratio. "We expect a more general application of our model ...

Ox-ox CMCs are high-strength, high-temperature and oxidation-stable materials that expand the design flexibility, life expectancy and efficiency of parts compared to existing metal parts. Ox-ox CMCs ...

Similar to conventional alloys, industrial operation environments for HEAs usually involve critical conditions such as exposure to high temperature, oxidizing/reducing gases, and acidic and ...

Protecting materials from high-temperature oxidation damage is already an established industry - fields such as aerospace, oil exploration and industrial manufacturing are reliant on a range of ...

This reality has motivated fundamental research into a new class of materials known as Ultra-High Temperature Ceramics (UHTC). These materials exhibit a unique combination of refractory and ...

If we want increased oxidation resistance at a lower temperature, then SiC fiber performs well. But the cost of SiC fiber is at least 10 times that of carbon fiber, most of it comes from Japan and the ...
