Test Analysis on Crack Propagation Rate of Axle Pipe Steel
The crack growth rate test of XCQ16 and XCQ16-1 axle steels were introduced using MTS material test machine. The test data of the crack propagation rate of axle steels has been analyzed by Paris formula. The results showed the crack propagation rate test of XCQ16 was faster than XCQ16-1, and the fatigue residual of XCQ16-1 life is longer. The correlated coefficient of the experimental data indicates that the result of this paper is comparatively ideal and has reference value to appraising the life span.
