Effect of the initial ECAP passes on crystal texture and residual stresses of 5083 aluminum alloyL.Romero-Reséndiz1,A.Flores-Rivera1,I.A.Figueroa1,C.Reyes-Ruiz3,I.Alfonso4,G.González11. Instituto de... of the Mg2Si and α-Al(Mn,Fe)Si precipitates for the sample at the initial condition were similar to those subjected to two ECAP passes. The peak broadening measured by X-ray diffraction revealed......
Initial formation of corrosion products on pure zinc in simulated body fluidLijun Liu1,Yao Meng1,Chaofang Dong1,2,Yu Yan2,Alex A.Volinsky3,Lu-Ning Wang11. State Key Laboratory for Advanced Metals... that the initial corrosion products on the pure zinc mainly consist of zinc oxide/hydroxide and zinc/calcium phosphate compounds.

Effects of initial grain size and strain on grain boundary engineering of high-nitrogen CrMn austenitic stainless steelZhen-hua Wang1,2,3,Jian-jun Qi2,3,Wan-tang Fu21. School of Mechanical...">18 Mn18 Cr0.5 N steel with an initial grain size of 28–177 μm was processed by 2.5%–20% cold rolling and annealing at 1000°C for 24 h,and the grain boundary character distribution was examined via......
INITIAL BINDING CAPACTIES OF CHLORIDE ION OF COMPONENTS IN HIGH-PERFORMANCE CONCRETE马保国摘 要:<正> An investigation is reported on the influence of different components of high performance concrete (HPC) on the initial binding capacities (IBC) of chloride ion. The testing results demonstrate that cement has the largest IBC, and the relative binding......
