| Abstract: | The toughness and abrasive resistance of super-coarse cemented carbide,and the adaptability of shield tools made from such carbide to underground earth and water-pressure in tunneling construction were studied.By the use of phase-transition control and densification techniques,quality cemented carbide was developed.It was proved by practical validation,such shield tools have same results as imported tools. |
