| Abstract: | The frac'ture mechanics analysis testing data show that the method of measureing frac'ture toughness of cemented carbide with three-point bend specimen with a breach in mountain shape is reliable. The discreteness of bata is little, the experiment can be repetitive and accord with change law of stracture-mechanical property of cemented carbide. |
