金属学报(英文版) doi:10.1007/s40195-016-0367-4

It is well known that, in kinetics, the interaction between dislocations and interstitial solute normally exerts strong solute drag effect on dislocations, leading to strong solution hardening of the metals. However, due to the low mobility of interstitial solute in many metals, thermodynamic aspect...

Interfacial Structures Governed Plastic Deformation Behaviors in Metallic Multilayers

Ming-Zhen Wei , Zhen-Hua Cao , Xiang-Kang Meng

金属学报(英文版) doi:10.1007/s40195-016-0377-2

In this work, we have investigated the mechanical properties of Cu/Ta, Ag/Cu and Ag/Nb multilayers with different heterogeneous interfaces. The results suggest that when individual layer thickness (h) is larger than 5-10 nm, the hardness/strength of three different multilayer systems has th...

Tensile properties of Cu with deformation twins induced by SMAT

Jinyu GUO , Ke WANG , Lei LU

材料科学技术（英文）

High density nano-scale deformation twins were introduced in the surface layer of Cu sample by means of surface mechanical attrition treatment (SMAT) at room temperature. The Cu sample with deformation twins shows a yield strength of about 470 MPa in tension tests. The significant strengthening may ...
