The microstructure and texture evolution of AZ31 magnesium alloy sheets in different processing states were investigated by optical microscopy and X-ray diffraction technique......
of the Mg-Li-X alloy to hot-rolling deformation is attributed at least partially to the insensitivity of residual stress and texture to hot-rolling. Key words: Mg-13Li-X alloy; residual stress; fracture... and the underlying mechanisms tensile tests, residual stress measurements and texture analyses were conducted in the present study. It is found that after a hot-rolling deformation of 50% at 200......

J..., Norway Received 23 October 2009; accepted 9 August 2010 Abstract: The microstructure and crystallographic texture characteristics of an extruded ZK60 Mg alloy subjected to cyclic extrusion......
are derived from deformation texture and grain refinement strengthening. 4 Conclusions 1) In as-cast Mg97Zn1Y2 alloy, the fracture is originated from phase interface and developed by cleavage planes... Tensile fracture of as-cast and hot rolled Mg-Zn-Y alloy with long-period stacking phase WANG Bai-shu(王柏树)1, 2, XIONG Shou-mei(熊守美)1, LIU Yong-bing(刘勇兵)3 1. State Key Laboratory of Automotive......
; microstructure; morphology; ductility; fracture texture 1 Introduction Since magnesium and magnesium alloys have many advantages such as low density, high specific strength, good cast ability, suitable.... Eventually, the adjacent cavities integrate together and the coupling interphase is cracked. Meanwhile on the each side of the fracture texture, a strait shape of dimple face appears on the surface......
. The crystallographic texture of the extruded sample changed from weak cube texture {001}<100> to texture {018}<081> during tension fracture. However, strong Brass {110}<112> in the hot-rolled sample was modi-fied into a mixture texture component of Brass {110}<112> and S {123}<634> during tension fracture. Texture evolution in the two samples during tension can be explained......
Adiabatic shear fracture in Ti-6Al-4V alloy ZHANG Jing1, TAN Cheng-wen1, 2, REN Yu1, YU Xiao-dong1, MA Hong-lei2, WANG Fu-chi1, CAI Hong-nian1 1.
