Abstract: Regularities, features and mechanisms of deformation and fracture processes of new ceramic materials – porous (=3-35 %) two-phase titanium nanolaminate-composites Ti3SiC2/TiC, Ti3AlC2/TiC, Ti4AlN3/TiN (content of TiC or TiN – 5-70 % vol.) at 20-1300 оС are established. Composites are made by reaction sintering. On increase in mechanical properties and resistance to deformation they settle down in the following sequence: Ti3AlC2/TiC–Ti4AlN3/TiN–Ti3SiC2/TiC. In porous nanolaminate-composites containing less tha…
