In situ formed AIN particles reinforced magnesium alloy matrix composites was successfully fabricated by bubbling nitrogen gas method.The composites obtained was characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM) equipped with an energy dispersive spectroscope (EDS) and transmission electron microscopy (TEM).The results showed that it is feasible to synthesize AIN particles in AZ91 alloy.The size of AIN particles ranges from submicron to several micron.The phase of Mg17Al12 was greatly refined due to the formation of AIN particles.The micro-hardness of AIN/ AZ91 composites is 88HV.Compared with matrix AZ91 alloy, the micro-hardness increased by 37.5%.

在自然环境中经常出现大气波导和海洋声波导现象,其对船载雷达和声纳超视距探测和探测盲区分布有着绝定性作用.电磁波和声波在波导中能否全部被陷获或部分被陷获以及被陷获能量多少,取决于波导界面波的反射临界角的大小.针对界面较弱时反射临界角过小无法计算问题,给出了相应的计算方法.两个新方法对所有界面反射波临界角的计算都有良好的效果.文章所提及的内容是一个发现,是对经典Snell理论的补充.Snell定理只揭

本工作对TiA1合金进行了模壳热等静压成型,并对成形样件的尺寸收缩、合金的化学成分、微观组织、拉伸性能,以及合金/模壳界面微观结构进行了分析.结果表明:采用陶瓷模热等静压成型制备出了高125mm的复杂样件,粉末致密化过程中,从外径向内、内径向外及高度三个方向发生尺寸收缩;成型过程中合金中氧含升高了130ppm;合金组织为均匀细小的双态组织,片层团及等轴晶尺寸为20μm左右;合金的室温延伸率达到1.
使用碳化钨和高碳铬铁为主要增强相,采用铸造方法制备出了三种不同成分的表面复合材料,研究了增强相成分对所制备表面复合材料组织和性能的影响.结果表明:碳化钨的加入改变了表面复合层组织中碳化物的形态和相对数量,适量的碳化钨可显著提高表面复合材料的硬度和耐磨性,但含量过多时会使表面复合材料的耐磨性有所降低.

建立复合铝合金高频焊管有限元模型,求解得到不同焊接参数下焊管不同位置的应力-时间变化曲线,分析表明焊管焊缝区部位的残余拉应力最大.通过焊缝拉伸试验和静水压爆破试验,结果表明焊管焊缝区部位的残余拉应力数值越大,其所能承受的爆破压力值越小,并且开口位置往往处于焊管焊缝区部位.一定程度上说明了通过有限元分析法能够较准确地反映焊接过程热应力的变化和冷却过程残余应力的变化情况.
