Intergranular Fatigue Cracking Behaviour in Aluminium刘蔚,王中光,夏月波摘 要:<正> In order to understand the basic mechanismof intergranular cracking in pure metals duringfatigue, stress-controlled push-pull fatiguetests were carried out with high purity aluminium.Tests were interrupted frequently so as to studythe grain boundary (GB) cracking behaviour......
Effect of rare earth elements addition on thermal fatigue behaviors of AZ91 magnesium alloy Hossein Bayani1,Ehsan Saebnoori2 (1.Department of Materials Science and Engineering,Sharif University... addition on thermal fatigue behaviors of AZ91 alloy were studied. Repeated heating and cooling cycles were applied on the samples at 170 and 210 ℃ to develop thermal fatigue cracks. Crack growth......
waveform loading was smaller than that by the sine waveform loading. The fatigue life became shorter when the cycle amplitude was larger. ATTEWELL [13] reported that in cyclic compression tests, the fatigue... constant, the loading rate and frequency have the same variation trend. In fact, relationship between loading rate and crack growth rate decides the fatigue life. When the loading rate is too high......
