The cavity growth was studied in uniaxial tension of superplastic magnesium alloy. An exponentially increasing cavity growth model was introduced into the numer
Based on the experiment of laminated pouring and accumulated liquid forging of 2A12 aluminum alloy,interface bonding of formed component with large altitude to
Using the one atom theory, the electronic structures of pure Cr, Mo and W with bcc structure were determined respectively as: [Ar](3dc)3.32(3dn)2.26(4sc)0.25(4s
When Cr, Mo and Ti were added to Fe-Al/Al2O3 composite, the bending strength and fracture toughness of the composite were increased sharply. The highest value o
