	1	Nanostructures and nanoprecipitates induce high strength and high electrical conductivity in a CuCrZr alloy显示文摘The mixed nanostructure mainly consisting of nanotwins and nanograins was obtained in a solid solution CuCrZr alloy by means of dynamic plastic deformation at cryogenic temperature.After subsequent aging treatments,the precipitation of Cr at nanometer scale provided further strengthening and brought substantial recovery of electrical conductivity.The aged nanostructured CuCrZr alloy exhibited a high tensile strength of 832MPa and a high electrical conductivity of 71.2%IACS.The details of precipitation tuned by nanotwin boundaries were demonstrated in this work.The combined strengthening of nanostructures and nanoprecipitates was discussed.

	2	Low-Temperature Nitriding by Means of SMAT显示文摘The microstructure in the surface layer of iron and steel samples can be refined at the nanometer scale by means of a surface mechanical attrition treatment (SMAT) that generates repetitive severe plastic deformation to the surface layer. The subsequent nitriding kinetics of the as-treated samples with the nanostructured surface layer is greatly enhanced so that the nitriding temperatures can be reduce to 300 - 400 °C regions. This enhanced processing method demonstrates both the technological significance of nanomaterials in advancing the traditional processing techniques, and provides a new approach for selective surface reactions in solids. This article reviews the present state of the art in this field. The microstructure and properties of SMAT samples nitrided will be summarized. Further considerations of the development and applications of this new technique will also be presented.	W.P.Tong H.W.Zhang N.R.Tao Z.B.Wang J.Lu K.Lu	2004	材料热处理学报2004，25，5：	3
	3	Tensile ductility and deformation mechanisms of a nanotwinned 316L austenitic stainless steel显示文摘A nanotwinned 316 L austenitic stainless steel was prepared by means of surface mechanical grinding treatment.After recovery annealing,the density of dislocations decreases obviously while the average twin/matrix lamella thickness still keeps in the nanometer scale.The annealed nanotwinned sample exhibits a high tensile yield strength of 771 MPa and a considerate uniform elongation of 8%.TEM observations showed that accommodating more dislocations and secondary twinning inside the nanotwins contribute to the enhanced ductility and work hardening rate of the annealed nanotwinned sample.

	4	Annealing-induced Hardening in a Nanostructured Low-carbon Steel Prepared by Using Dynamic Plastic Deformation显示文摘Lamellar nanostructures were induced in a plain martensitic low-carbon steel by using dynamic plastic deformation at room temperature.The nanostructured steel was hardened after annealing at 673 K for20 min,with a tensile strength increased from 1.2 GPa to 1.6 GPa.Both the remained nanostructures and annealing-induced precipitates in nano-scale play key roles in the hardening.

	5	Orientation dependence of deformation twinning in Cu single crystals显示文摘Cu single crystals were subjected to dynamic compression plastic deformation to investigate orientationdependent twinning.The experimental results showed that twinning is closely related to the ratio of the maximum Schmid factor for twinning partial(m_T)to the maximum Schmid factor for perfect dislocation(m_S),i.e.,m_T/m_S,rather than m_T.The twin volume fraction V_Tincreases with the m_T/m_Svalue and the most favorable orientation for twinning has the maximum m_T/m_Svalue(1.15).The relationships of m_T/m_Swith both effective stacking fault energy γ_(eff)and threshold stress for twinning τ_Twere established for understanding orientation-dependent twinning.Further insights into the orientation-dependent twinning and guidance for developing bulk high density nanotwinned materials are provided.
