摘要: Compact ceramic materials based on the M n + 1 AX phases in Ti-Cr-Al-C system are produced by forced self-propagating high-temperature synthesis (SHS) compaction. The mechanisms of structure and phase formation synthetic products, as well combustion macrokinetics SHS mixture, studied. Complex investigations structure, composition, physical mechanical properties new Ti 2 - x Cr AlC synthesized at different charging parameters ( = 0, 0.5, 1, 1.5, 2) per- formed. highest content (96-98%) composition products is found to be samples where just one host elements (titanium 0) or chromium 2)) present. pro- duced have a high heat resistance, increase concentration favorable an appreciable growth resistance oxidation.
