Effect of thermal stability of M_n+1AX_n phases on microstructure and mechanical properties of M_n+1AX_n/ZA27 composites

Abstract

Special layered structure endows ternary M n+1 AX n phase ceramics with good electrical and thermal conductivity, excellent abrasive resistance, and perfect thermal shock resistance. In this work, three kinds of M n+1 AX n phase ceramics (Ti 3 SiC 2 , Ti 3 AlC 2 , and Ti 2 SnC) were chosen to reinforce the ZA27 alloys, respectively.

Electrochemical corrosion behaviors of Ti3SiC2/Cu composites in a 3.5% NaCl solution

“…Ti 3 SiC 2 is a typical member of MAX phase with a ternary layered structure. It possesses combination characteristics of metal and ceramic, [1][2][3] such as good electrical and thermal conductivity, relatively low hardness, high specific strength, excellent high-temperature mechanical properties, and good corrosion resistance; thus, it was widely used in high-temperature environments, chemically resistant environments, and functional materials fields. [4][5][6][7][8] JOVIC et al found that Ti 3 SiC 2 was relatively stable and passivated in the HCl, H 2 SO 4 , and NaOH solutions.…”
