Effect of carbon content on microstructure, hardness and wear resistance of CoCrFeMnNiCx high-entropy alloys

Journal of Alloys and Compounds, 2020
A set of CoCrFeMnNiCx (x = 0, 0.3, 0.6, 0.9, 1.2) high-entropy alloys (HEAs) were prepared using mechanical alloying and spark plasma sintering. The influence of carbon content on the microstructure, hardness, scratch resistance and wear resistance of ...

A model of hardness and fracture toughness of solids

Journal of Applied Physics, 2019
Hardness and fracture toughness are some of the most important mechanical properties. Here, we propose a simple model that uses only the elastic properties to calculate the hardness and fracture toughness. Its accuracy is checked by comparison with other

Effect of reinforced aluminium alloy LM30 with pure ceramic particles to evaluate hardness and wear properties

Materials research innovations (Print), 2020
In this paper, the hardness and wear properties of pure ceramic particles like silicon carbide, boron carbide and graphite are considered in micron size with the reinforced aluminium LM30 metal matrix composites. The stir casting setup is used to prepare
