Publikováno v: Open Ceramics, Vol 15, Iss , Pp 100398- (2023)

Mechanical properties of two ternary carbides MAX phases (Ti2AlC and Ti3AlC2) were investigated under cyclic bending tests with coupled acoustic emission monitoring (AE). Results show significant differences in terms of observed microstructural chang

Publikováno v: Advanced Engineering Materials. 18:1952-1957

In order to better understand the thermomechanical behaviors of Ti3SiC2 and Ti2AlC ceramics, sintered by spark plasma sintering process (SPS), ultrasonic pulse echography in “long bar mode” (US) and acoustic emission (AE) techniques are applied.
