The former two types are brittle ones, and the fracture strain of pyrolytic carbon matrix is the controlling factor of the strength.
前两种为脆性断裂方式，热解炭基体的断裂应变是这类材料强度的控制因素。
The results show that interface element diffusion and reaction on interface in vacuum hot-pressing sintering processing improved interface strength. Fracture occurred mainly in Al matrix.
结果表明，真空烧结过程中出现了界面反应，改善了界面结合强度，断裂破坏主要在基体上进行。
Thus it is affirmed that the combination of the two materials are matchable and that the strength and fracture toughness of alumina-silicate ceramic matrix have been greatly improved.
本课题所试制的铝硅酸盐陶瓷基体的强度和断裂韧性有较大的提高。
