Effect of Mo on microstructural characteristics and coarsening kinetics of γ’ precipitates in Co–Al–W–Ta–Ti alloysH.J.Zhou1,F.Xue1,H.Chang2,Q.Feng11. State Key Laboratory for Advanced Metals... temperature,volume fraction,coarsening behavior of Y’ precipitates and the partitioning behavior of alloying elements as well as lattice misfit of Y/Y’ phases influence the creep behavior of Ni......
Trans. Nonferrous Met. Soc. China 22(2012) 1866-1871 Formation of precipitates and recrystallization resistance in Al-Sc-Zr alloys JIA Zhi-hong1,2, Jostein R?YSET3, Jan Ketil SOLBERG2, LIU Qing1 1..., precipitation and distribution of Al3(Sc,Zr) precipitates were found to be strongly related to the Sc content. With increasing the Sc content, the average radius of the precipitates decreases, while the number......

. The elastic modulus of Li-containing alloys decreases with the increment of precipitates though it is higher than that of Al-Zn-Mg-Cu alloy. Key words: Al-Zn-Mg-Cu-Li alloys; ageing; precipitates; elastic... is to study the elastic modulus of Al-Zn-Mg-Cu-Li alloys under artificial ageing condition, and the relationship between precipitates and elastic modulus. 2 Experimental The two alloys investigated......
wire was found to be 0.04 %/K. The large decrease in dε/dT by cold working effect suggested that an introduction of dislocation was more effective than precipitates for lowering dε/dT. 关键词:Ti-50.5Ni alloy; TGA treatment; dislocations; precipitates; temperature dependence of elongation; [全文内容正在添加中] ......
