【Abstract】 The material is fabricated under strict control of chemical composition and with optimized forging and heattreatment technologies. A series of tests, including the tests of monotonic mechanical, impact and fatigue properties, and metallurgical observations, are performed to inspect the material. The results reveal that it can meet the requirements of the brake disk function.更多还原
