The role of pore microstructures on the susceptibility of MAX phases (Ti3SiC2, Ti3AlC2, Ti2AlC, Ti2AlN2, Ti4AlN3) to thermal dissociation at 1300-1550 °C in high vacuum has been studied using in-situ neutron diffraction. Above 1400 °C, MAX phases decomposed to binary carbide (e.g. TiCx) or binary nitride (e.g. TiNx), primarily through the sublimation of Aelements such as Al or Si, forming in a porous surface layer of MXx. Positive activation energies were determined for decomposed MAX phases with coarse pores but a negative activation energy when the pore size was less than 1.0 µm. The role of pore microstructures on the decomposition kinetics is discussed. | |
