Effects of Zinc and Calcium Concentration on the Microstructure and Mechanical Properties of Hot-Rolled Mg-Zn-Ca Sheets

Jun Luo , Hong Yan , Nan Zheng , Rong-Shi Chen

金属学报(英文版) doi:10.1007/s40195-016-0378-1

Four kinds of Mg alloys with different Zn and Ca concentration were selected to analyze the effect of Zn and Ca concentration on the microstructure and the mechanical properties of Mg-Zn-Ca alloys. It was found that Zn and Ca concentration has a great influence on the volume fraction, the morphology...

Influence of Microstructures and Textures on the Torsional Behavior of Pearlitic Wires

Y , ong LIU

材料科学技术(英文)

The microstructure, texture characteristics and torsion ability of two kinds of steel wires were investigated. The eutectoid steel wires were produced by hot and cold drawing with severe deformation. The torsinability of steel wires was measured under two cases, i.e. there exists either fiber textur...

Formation of Copper Type Texture in Cold Rolled Aluminum Sheet

Weimin MAO

材料科学技术(英文)

The formation process of copper type rolling texture in f.c.c. metals was simulated based on a deformation model considering internal reaction stresses induced by the neighboring matrix as well as external shear stress induced by rollers. It is indicated that the external shear stress will reduce th...

炭材料中的组织

稻垣道夫

新型炭材料 doi:10.3969/j.issn.1007-8827.1999.02.001

炭材料的基本结构单元是各向异性碳六角层面.基于择优取向的图型,炭材料中的纳米大小的组织(纳米组织)可分为沿面、轴和点的取向以及任意取向.从这种纳米组织的分类可以容易地了解到为什么炭材料能有如此多的形态:层片、纤维、球和不规则的粒子,以及为什么有如此宽广的性质.文中还简要地介绍了表征这些纳米组织的主要...
