Many intermetallic compounds display an attractive combination of physical and mechanical
properties, including high melting point, low density and good oxidation or corrosion …

A continuing quest in science is the development of materials capable of operating
structurally at ever‐increasing temperatures. Indeed, the development of gas‐turbine …

Jet turbine engines have benefited from decades of development of nickel-based
superalloys, which have allowed a steady increase in engine operating temperatures and …

In the last one and a half decades, a great deal of fundamental and developmental research
has been made on high-temperature structural intermetallics aiming at the implementation of …

The aerospace field is traditionally strategic for the development of novel materials needed
for the specific requirements of aircraft structures and propulsion systems. A large number of …

This article discusses three main points. First, ultrahigh-temperature materials offer a large
return to the propulsion community and to the economy, but replacing Ni-based alloys is a …

In the past decade, multi-principal element high-entropy alloys (referred to as high-entropy
alloys, HEAs) are an emerging alloy material, which has been developed rapidly and has …

Continuous exploration of high-temperature structural materials is being driven by the needs
of gas-turbine engines capable of withstanding the high-temperature environment …

Mo-Si-B intermetallics consisting of the phases Mo 3 Si and Mo 5 SiB 2, and a molybdenum
solid solution (“α-Mo”), have melting points on the order of 2000° C. These alloys have …

Abstract The search for Mo-Si-B based alloys exhibit excellent high-temperature wear
resistance is highly demanding for their structural applications. For this target, the Mo-Si-B …
