Высокотемпературные механические испытания композитов на основе Ti3Al(Si)C2, полученных искровым плазменным спеканием прекерамических бумаг

Abstract

In this work the flexural strength of Ti3Al(Si)C2 - based composites was measured at room temperature, 800 and 1000 °С. Preceramic paper - derived composite sintered at 1150°С and 50 MPa demonstrates the flexural strength over 900 MPa at room temperature. The flexural strength of composites decreased from 700 and 620 MPa with increasing testing temperature from 800 and 1000 °С, respectively. Moreover, the composites demonstrate plastic deformation at 1000 °С, which results in anomalous displacement of sample under mechanical load.
