研究了镁对Al-Mg-Si合金熔体氧化热力学与动力学的作用,以及对Al2O3/Al-Mg-Si复合材料组织与性能的作用。热力学与动力学分析表明:镁促进了Al2O3的形核和长大,Al2O3/Al复合材料的性能改善是由于尖金石(MgAl2O4)的分解所导致的组织细化。但在合金中,镁含量太高或太低都对Al2O3的形核和长大不利。

以铜和铌作为中间夹层,真空扩散焊接Ti(C,N)/Ni,研究温度和时间等主要工艺参数对Ti(C,N)/Ni界面微观组织和性能的影响．结果表明,当扩散焊接的温度低于1273 K时,界面的夹层材料基本保持不变,界面的微观组织为Cu/Nb层状物,铜在镍中有少量扩散;而当扩散焊接的温度为1523 K时,界面微观组织在初期为Ni_8Nb的金属间化合物+离散析出的CuNi固溶体,到后期变为靠近Ti(C,N)侧为(Ti,Nb)(C,N)+Nb_7(Ni,Ti,Cu)_6+NbNi_3层,靠近Ni侧为NiCu+NbNi_8层．这表明,液态Cu为过渡液相,通过Ni的溶解而形成CuNi过渡液相,加速了Nb在CuNi过渡液相中的溶解．由此产生的NiNbCu过渡液相能浸润Ti(C,N),并在界面处形成少量的(Ti,Nb)(C,N)固溶体合金,从而提高了界面的结合性能,界面剪切强度可达到140 MPa．

本文考察了德国监事会制度生成及演进的路径。在外部环境的复杂性与不确定性不断增强的情况下,公司的经营权逐渐转移到董事会手中。为了在经营中维护投资者的利益,监事会作为一种监督制衡机制得以产生。在德国监事会制度变迁过程中,依存一定的历史路径,不同的利益主体通过不断的博弈,最终由国家主导,在监事会中确立了劳资双方代表人数均等以及银行代表、独立监事共同参与的机制,实现了监事会从机能到结构的创新发展。根据德国监事会制度演进的经验,本文提出了我国监事会制度建设的政策建议。
