Because it owns many excellent properties such as low density, higher hardness and red-hardness to carbide, chemical stability, good inoxidizability, less friction coefficient to steel, higher thermal expansion to carbide, and contains no or less resource-limited and expensive WC and Co, it is applied to industrial production to promote work efficiency and decreases the cost.

由于其具有密度低、硬度和红硬性高于硬质合金、化学稳定性和抗氧化性好、对钢的摩擦系数小、热膨胀系数高于硬质合金等性能特点，再加上其不含或少含资源有限、价格昂贵的WC、Co物质，应用于工业生产有利于提高工效、降低成本，因而国内外对Ti基金属陶瓷进行了大量的研究，同时其作为新型的刀具材料在金属切削领域内也得到了广泛地应用。

Calculations on the basis of the self-consistent approximation are used to study the effects of slit cracks, elliptical cracks and penny-shaped cracks. The influence of slit cracks on the elastic moduli under all kinds of loading conditions is discussed by Betti's reciprocal theorem and Irwin's relation describing the released energy rate of fracture to the stress intensity factors. The friction between the cracks' surfaces is taken into account for the closed cracks.
