were characterized by a variety of techniques. The results of X-ray diffraction(XRD) show that there are two cleavage faces, which are(110) and(101). The peaks are in high intensity and good symmetry......
and the fracture takes place along the Ti2Ni and Ti Ni phase upon tensile loading.The existence of cleavage pattern on the fracture surface indicates the brittle nature of the joints.关键词:......
to the figure (245 MPa) of adding Mg-Nd intermediate alloy. The tensile fracture mechanism of as-cast AZ31 transformed from cleavage fracture into quasi-cleavage fracture.关键词:......
occurs when the matrix dislocations pile up at the precipitation and matrix interfaces, and the interfacial dislocations may become precursors to the misfit dislocations, which can form small cleavage......
at -196 °C, which promoted the cleavage fracture in the steels with large-sized grains. Refining the grain size could improve the strength of the high-Mn austenitic steels without impairing......
propagation rate of the specimen inclined at 45o is between the two directions. The crack tip propagates by both transgranular and intergranular fractures. Fatigue fractures consist of cleavage plane or quasi-cleavage and are brittle fractures. The fatigue striation occurs for specimens inclined at 45o and its size is 3-15 μm.关键词:......
is suggested that the main strengthening-toughening mechanisms are grain refinement strengthening and Al2O3 dispersion strengthening.The fracture of larger NiAl grain is the transgranular cleavage......
Aggregation of Gold Nanoparticles and DNA Damage by Atomic Force Microscopy胡善洲1,刘鹏11. Department of Chemistry, School of Science, Wuhan University of Technology摘 要:The plasmid DNA binding and cleavage activities with gold nanoparticles(Au-NPs) were investigated by the integrated tools of UV-vis spectroscopy, atomic force microscopy(AFM), and DNA......
microscope examination reveals a transition of the fractured surfaces from cleavage fracture to quasi-cleavage fracture resulting from the Y2O3 addition.关键词:......
characterized by cleavage fractures,river patterns,and tear ridges.And the sample after pre-cold rolling combined with aging presented more equiaxialdimples with a great amount of cracked particles in them.The......
