Abstract
A new type of composites containing eutectic oxide fibres and a high entropy alloy (HEA) with a melting point of about 1450 °C as the matrix is obtained via liquid infiltration route. A low pressure of argon gas necessary to infiltrate a fibre bundle with the molten matrix alloy is an evidence of good wetting in this system that provides a sufficiently high strength to the fibre/matrix interface. Composite specimens were tested to measure the strength at 20-1300 °C. It was found that the composite strength does not decrease to a temperature of 1200 °C. The analysis of the microstructure and strength data suggests an expectation of a high creep resistance of the composites under development.
