Sergey N.Kulkov Alexander G.Melnikov Institute of Strength Physics and Materials Science , The Russian Academy.of Science , Siberian Branch , Tomsk , 634055 , RussiaYanchun ZHOU Shengqi CHEN Zhe QU Institute of Metal Research , Academia Sinica , Shenyang , 110015 , China

材料科学技术（英文）

The effects of shock loading on the morphology,grain growth during heating and phase transforma- tion of ZrO_2 have been investigated.It is shown that shock loading may be efficiently used to modify submicron ceramic powders with nanocrystalline structure.After shock loading,the critical diameter of...

Realization of Superplastic State of Polycrystals under Grain-boundary Diffusion

Yu.R.Kolobov and I.V.Ratochka(Institute of Strength Physics and Materials Science , Siberian Branch of the Russian Academy of Sciences , 634055 , Tomsk , Russia)

材料科学技术（英文）

Creep behaviour of Mo and Fe polycrystals has been studied for a wide range of Strain rates in the presence of grain-boundary diffusion flux of Ni. The role of the impurity grain-boundary diffusion and grain-boundary migratin in the realization of the superplastic strain of metals under these condit...

S.V.Alekseev S.G , Psakhie V.E.Panin Institute of Strength Physics and Materials Science of the Russian Academy of Sciences , Siberian Branch.Tomsk , 634055 , Russia

材料科学技术（英文）

The influence of shear deformation on the behaviour of Mg and Zn impurities as well as self-interstitial atoms in Al was studied using molecular dynamics method.The profilies of potential relief were calculated in directions of possible migration of interstitials.It was found that under load- ing th...
