| 1 | TENSILE STRENGTH AND CREEP RESISTANCE OF Mg-9Al-1Zn BASED ALLOYS WITH CALCIUM ADDITION显示文摘Small amount of calcium addition to the Mg-9A1-0.8Zn-0.2Mn (AZ91) alloy resulted in the obvious influence on mechanical properties. The yield strength of the alloys increased with the increase of Ca addition and maximum strength was obtained from the alloy containing 0.15% of Ca. The creep resistance at the temperatures between 150-200℃ was also significantly increased with Ca addition. The creep rate (at 200℃, 50MPa) of the alloy with00.15% of Ca addition was one order of magnitude lower than that of the base alloy (AZ91). Microstructural observations revealed that the addition of calcium refined the microstructure and enhanced the thermal stability of the β precipitates, which accounted for the improvement of creep resistance at high temperatures. | Y.S.

| 2 | PREPARATION STUDY OF SEMI-SOLID 60Si2Mn SPRING STEEL SLURRY显示文摘The nondendritic semi-solid slurry preparation of 60Si2Mn spring steel is studied in this paper. The experiments show that when stirred for 2 minutes under the test condition, the semi-solid slurry with 50%-60% fraction solid phase and spherical primary austenite in the size of 100-300μm can be obtained and is easy to be discharged from the little bottom hole of the stirring chamber. The more homogeneous temperature field and solute distribution of the 60Si2Mn spring steel melt appear because of the electromagnetic stirring, which restrains the formation of large primary austenitic dendrites and create a base to form spheroidized structure. The stronger temperature fluctuation in the melt with many rosette primary austenites caused by stirring and the remelting of the secondary arm roots in the same time are the most important reasons for deposition of spheroidized primary austenites. | W.M.

| 3 | EFFECT OF TOOL WEAR ON MICROSTRUCTURE, MECHANICAL PROPERTIES AND ACOUSTIC EMISSION OF FRICTION STIR WELDED 6061 Al ALLOY显示文摘工具状况是在磨擦的主要担心之一促使焊接(FSW ) ,因为包括尺寸和形状的工具大头针的几何条件强烈被连接到微观结构和焊接的机械性能。工具穿发生在 FSW 期间,特别为与大量磨料焊接金属矩阵 composites,融化的粒子,和高度削尖材料,它显著地帮助工具穿并且败坏焊接的机械表演。当察觉到的声学的排放(AE ) , metallographic sectioning,并且张力的测试被采用在各种各样的工具中评估焊接质量时,有不同大头针穿层次的工具被用来焊接 6061 艾尔合金穿条件。结构的描述证明工具穿在金块地区为虚空的形成防碍焊接质量和报道。样品的张力的测试分析证实最终的张力的力量和收益力量被虚空的形成不利地由于工具在金块影响穿。失败地点清楚地在张力的测试期间取决于工具的状态穿,它导致了在金块和工具的结构之间的关系的分析穿。在焊接期间记录的 AE 签名表明 AE 点击与增加专注于更高的振幅工具穿。结果证明察觉到的 AE 为工具的联机监视提供一个潜在地有效的方法穿。 | W.M.

| 4 | TENSILE PROPERTIES AND CREEP RESISTANCE OF AZ91 ALLOY CONTAINING ANTIMONY显示文摘Small amount Of antimony addition to the Mg-9Al-0.8Zn-0.2Mn (AZ91) alloy resulted in the obvious increase of tensile strengths at both ambient and elevated temperatures.The creep resistance at the temperatures ap to 200℃ was also improved significantly by antimony addition. Mcrostructurul observations revealed that the addition of antimony modified morphology of the α(Mg17Al12) phase and caused the formation of some rod-shaped precipitates Mg3b2 at grain boundaries. These precipitates have high thermal stability and play an important role for strengthening groin boundaries at elevated temperutures. | Yuan, G.Y. Sun, Y.S. Zhang, W.M.

| 20 | SPLITTING A CONCAVE DOMAIN TO CONVEX SUBDOMAINS显示文摘We will study the convergence property of Schwarz alternating method for concave region where the concave region is decomposed into convex subdomains. Optimality of regular preconditioner deduced from Schwarz alternating is also proved.It is shown that the convergent rate and the condition number are independent of the mesh size but dependent on the relative geometric position of subdomains.Special care is devoted to non-uniform meshes, exclusively, local properties like the shape regularity of the finite elements are utilized. | H.C.
