焊合

Through using second diffluence with protruding die, improving the metal flow equably and jointed sufficiently, the extrusion dies for these kinds of industrial aluminium profiles are designed possibly.

对上模采取二次分流的形式来改善金属均匀流动和充分焊合，从而合理地设计出这类型材的模具。

The restraining effect of Si decreases with decreasing temperature. Fe reduces the chemical potential gradient of the dissolution of iron into molten Al and the driving force of the diffusion of Al into die.

Fe的作用主要是降低模具钢向铝熔体中溶解的化学位梯度和铝向模具中扩散的驱动力，因而，合金中的Si、Fe元素可以降低合金的焊合倾向性。

The results show that a sound bonded interface is obtained without sheet inclusion, pore and unbinding. The microstructure consists of bulk α-Mg phase and needle compound in the weld metal, element Al diffuses along the grain boundary of the substrate into the welding line. A little Y diffuses into the base metal. A little Mn and Cu segregate and element Ni distributes homogeneously and no segregation appears in weld area.

结果表明：界面接合良好，未观察到片状夹杂物、气孔及未焊合等缺陷；焊缝区由块状α-Mg相和针状化合物组成，基体中的Al元素通过晶界扩散偏聚到焊缝中，微量Y元素扩散到基体中，有少量的Mn和Cu元素发生偏聚，Ni元素分布均匀，没有发生偏聚现象。

The effects of Si and Fe in aluminum alloy on the soldering tendencies had been studied by hot dip aluminizing.

通过热浸铝试验，分析了铝合金中的Si、Fe元素对铝合金熔体与模具钢间的相互作用及焊合倾向性的影响。

The experiment of hot dip aluminizing had been carried out in order to study the interaction between die casting die and aluminum alloy and the effect of Si on soldering tendency between die and aluminum alloy casting.

为了研究压铸模与铝合金的相互作用，探讨Si对压铸模与铝铸件焊合倾向性的影响，进行了热浸铝试验。

About 35,000 pages survived the war, buried in milk churns and tin boxes.

一些包装的焊缝焊合的非常密实，而一些包装的焊缝开裂了。

This kind of quartz stone cutting tool is a technological innovation product, the design structure is novel, it change the use of sole grade grinding compound which is already a traditional manufacture method, it simultaneously used the rough and fine grain grinding compound in the cutting tool different part, ie, by the electricity chromium welded skill, weld the large grain diamond grinding compound on the tool bit top (4050 #) and weld the tool bit both sides the metal polish fine grain grinding compound which the nominal grade value is one level up smaller than large grain grinding compound 100-120

这种石材切具属一项技术创新产品，设计结构新颖，这在于它改变了使用单一粒级磨料的传统制作方法，而是在切具刀头不同部位同时使用粗细粒磨料，也就是在刀头顶面和刀头两侧由电铬焊合艺分别同定粗粒金刚石磨料(4050目)和标称粒级值小于粗粒磨料一级以上的金属抛光用细粒磨料100-120目
