High-temperature short-term and long hardness of sintered compact and porous titanium-siliceous carbide ti3sic2
The ternary compound of titanium-siliceous carbide Ti3SiC2, one of the representatives of Nan laminates, prepared by solid-phase sintering is investigated in compact and porous (q=0.03-0.41) states. Features of its short-term and long-term hardness (Р=10 N) behavior in the temperature range from 20...

| Summary: | The ternary compound of titanium-siliceous carbide Ti3SiC2, one of the representatives of Nan laminates, prepared by solid-phase sintering is investigated in compact and porous (q=0.03-0.41) states. Features of its short-term and long-term hardness (Р=10 N) behavior in the temperature range from 20 to 1200˚С at a holding time of 1-60 min were studied. It is shown that a temperature of about 700°С and holding time under load of about 10 min are critical values of the indentation procedure that correspond to an intensive decrease of hardness. The presence of porosity results in a decrease in hardness. a deformation scheme of compact and porous titanium-siliceous carbide Ti3SiC2 in the temperature range from 20 to 1200˚С is proposed. . |
