The periodic corrugations result from the interactions between the reflected elastic waves by the boundaries of amorphous ribbon and the stress fields of the crack tip.","authors":[{"authorName":"Xifeng LI","id":"7d0669ff-604f-4994-8598-9417a51c7f10","originalAuthorName":"Xifeng LI"},{"authorName":" Kaifeng ZHANG","id":"cc8c1429-1c0a-46c9-bd3c-6dd17f8f3bff","originalAuthorName":" Kaifeng ZHANG"},{"authorName":" Guofeng WANG","id":"f47d228e-7c1a-4d11-9423-9609655d952c","originalAuthorName":" Guofeng WANG"}],"categoryName":"|","doi":"","fpage":"745","id":"9b9dbb59-c7fc-41c2-b451-33c32b391b32","issue":"5","journal":{"abbrevTitle":"CLKXJSY","coverImgSrc":"journal/img/cover/JMST.jpg","id":"11","issnPpub":"1005-0302 ","publisherId":"CLKXJSY","title":"材料科学技术(英文)"},"keywords":[{"id":"4caeccb8-5c47-4f9b-a4c4-16c9b6803102","keyword":"Nanoscale periodic corrugation","originalKeyword":"Nanoscale periodic corrugation"},{"id":"eee2434e-06e0-4eaf-85a2-b808874ac325","keyword":"断裂空洞","originalKeyword":"断裂空洞"},{"id":"5cc3f0d4-231d-4699-bdf1-00ebb5889a06","keyword":"拉伸断裂","originalKeyword":"拉伸断裂"}],"language":"en","publisherId":"1005-0302_2008_5_17","title":"Nanoscale Morphology in Tensile Fracture of a Brittle Amorphous Ribbon","volume":"24","year":"2008"},{"abstractinfo":"Rolling Contact Fatigue(RCF) is a cumulative damage phenomenon when metals are subjected to repeated contact stresses. The fomation of pitting on the contact surface is the result of the rolling contact fatigue. The morphologies of rolling contact fatigue fracture of the har- dened steels (86CrHoV7, 42CrMo) show that strong resemblance in fractuye mechanisms exists between rolling contact fatigue and uni-axial fatigue. Since fatigue striations are hardly observed in hardened steels under uni-axial fatigue, it is interesting to note that the state of stress in rolling contact fatigue is more favor- able to ductile fractures than in uni-axial fatigue.","authors":[{"authorName":"WANG Xu","id":"41d9a8d5-d6c9-4672-b894-241ccfb6be64","originalAuthorName":"WANG Xu"},{"authorName":"ZHANG Shouhua","id":"a2c92eb2-4dc7-479c-8b11-9c8cfba1c082","originalAuthorName":"ZHANG Shouhua"},{"authorName":"CUI Peiyong Beijing University of Science and Technology","id":"40e6cbf2-c964-4bdf-9e70-f7808132613c","originalAuthorName":"CUI Peiyong Beijing University of Science and Technology"},{"authorName":" Beijing","id":"625dd621-3394-4a3e-8118-d47a8908ccd8","originalAuthorName":" Beijing"},{"authorName":" China.

The fatigue endurance limits (defined as 107 cycles without failure), based on the applied stress range, for three-point and four-point loading conditions were approximately 475 MPa and 350 MPa, respectively. All fracture surfaces were found to be composed of four main regions: a crack-initiation site, a stable crack-growth region, an unstable fast-fracture region, and a melting region. Finely spaced parallel marks, similar to fatigue striations found in crystalline alloys, oriented somewhat perpendicular to the direction of crack propagation were observed in the stable crack-growth region. Analyses of these marks found that their spacing increased with increasing stress-intensity-factor range.

Mg-based amorphous glass fractures on one major plane and shows a planar and smooth fracture surface upon quasi-static loading. The fracture surface of composite is rough,which is composed of a great deal of small mirror planes in quasi-static tests. Rugged fracture surfaces were observed both in Mg-based amorphous glass and composite during dynamic deformation. A large area of molten liquid spreads over the whole fracture surface, indicating more severe temperature rise occurs during dynamic deformation. When encountering SiC particulates during propagation, cracks cut through (sometimes being stopped inside the particulate) or bypass the particle. The fact that cracks cut through or bypass particles reflects the strong bonding at the particle-matrix interfaces and the effective load transfer from matrix to the reinforcing particles. The block function to crack propagation due to the presence of particles is expected for shear bands before cracking initiates inside the shear bands, avoiding the formation of major shear band and the catastrophic failure likely.
