Structure stability of Ti3AlC2 in Cu and microstructure evolution of Cu–Ti3AlC2 composites

Thermal stability of Ti3AlC2 in Ar-10vol.%CO atmosphere

“…It was reported that after the sublimation of Si from (0 0 0 1) surface of Ti 3 SiC 2 , the relaxation and recrystallization of the residual Ti 3 C 2 resulted in the parallel relationship between the (1 1 1) plane of the transformed Ti 3 C 2 and the (0 0 0 1) plane of Ti 3 SiC 2 [18]. Similar result has also been observed in Zhang's investigation on the structure stability of Ti 3 AlC 2 in Cu [19]. Analogously, the porous Ti(O,C) formed after the decomposition of Ti 3 AlC 2 in this work is also extended to Ti 3 AlC 2 grains.…”

Surface strengthening of Ti3SiC2 through magnetron sputtering Cu and subsequent annealing

“…less than the threshold Si content constituted of Ti 3 SiC 2 layered structure, the topological transformation from hexagonal Ti 3 SiC 2 to cubic TiC x happens. Similarly, in the previous investigation of structure stability of Ti 3 AlC 2 in Cu, 17 the reaction was determined to be diffusion of Al from Ti 3 AlC 2 into Cu to form Cu(Al) solid solution first, while Ti 3 AlC 2 retained its structure under the partial loss of Al. And then further depletion of Al resulted in highly defective Ti 3 AlC 2 .…”

Methods of MAX-phase synthesis and densification – I

“…Zhang et al [75] prepared Cu/Ti 3 AlC 2 composites by HP and investigated its structure stability. XRD results showed that Cu and Ti 3 AlC 2 could coexist at temperatures below 850 °C.…”
