New fracture morphology of amorphous Fe78Si9B13 alloy ZHANG Kai-feng(张凯锋), LI Xi-feng(李细锋) School of Materials Science and Engineering, Harbin Institute of Technology, Harbin150001, China...; Abstract: The tensile fracture morphology of a brittle amorphous Fe-based ribbon was investigated by scanning electron microscopy(SEM). The fracture surface consists......
The Morphology of Rolling Contact Fatigue Fracture of Hardened Steels王绪,章守华,崔佩庸摘 要:<正> Rolling Contact Fatigue(RCF) is a cumulativedamage phenomenon when metals are subjectedto repeated contact stresses. The fomationof pitting on the contact surface is the resultof the rolling contact fatigue. The morphologiesof rolling contact fatigue fracture......
measured by compression tests. The structure and thermal characteristics were analyzed by XRD and DSC, and the fracture surface morphology was examined by SEM. The glassy alloy with 4 mm in diameter...-Al bulk metallic glass; compression fracture behavior; fracture morphology; adiabatic heating......
Fracture morphology and crack mechanism in pure polycrystalline magnesium under tension-compression fatigue testingLi Tan1,Xi-Yan Zhang1,Ting Xia1,Guang-Jie Huang1,Qing Liu1,21. College of Materials... were 0.5% and 1.0% respectively,and the results showed that the fatigue deformation of different strain amplitude produced two typical fatigue fracture morphology,and when the strain amplitude was 1.0......
of hydraulic fracture propagation and reveal the effect of fracturing parameters on fracture morphology in weakly consolidated sandstone, finite element numerical model of fluid-solid coupling... for weakly consolidated sand fracturing In order to investigate the influences of rock property and fracturing parameters on the fracture morphology of unconsolidated sand in the process of frac-gravel......
of Yb addition on the strength and fracture toughness of Al-Zn-Mg-Cu-Zr aluminum alloy was investigated by measuring tensile properties and fracture toughness. The surface morphology was observed...
