The model of metal Half-Ball proposed in this paper was aimed to study the material transport mechanism of solid metal powders during HP (hot pressing) and HIP (hot isostatic pressing). In this investigation theory of creep deformation mechanism, the so-called Nabarro-Herring diffusion mechanism and plastic deformation mechanism by dislocation movement, were considered and applied to calculate the relation between absolute shrinkage(h+h0)and time t at constant temperature and under constant pressure: The relation was given as; (h+h0)n =At. Where A is constant, the exponent n is applied to determine the material transport mechanism of sintering neck(n=1 for diffusion, n=4.5 for plastic deformation by dislocation climb). The sintering experiments of Cu, Ni, Ag Half Ball under pressure supported that this method for determining material transport mechanism is rational and simple to serve. It is shown that at T=700℃, σ≥1.2×108 dyn/cm2 or T=800℃, σ≥7×107 dyn/cm2 the material transport mechanism may be mainly considered as plastic deformation controlled by dislocation climp.

本文为研究热压和热等静压过程中烧结颈部的物质迁移机构,建立了金属半球对模型。应用Nabarro-Herring,Weertman等人对蠕变变形机构研究的成果,从理论上导出了恒温恒压下半球对的绝对收缩量(h+h_0)随时间t变化关系:(h+h_0)~n=At。并用式中指数n的取值来判断颈部物质迁移机构。(当n=1时为扩散,n=4.5为位错攀移)。Cu、Ni、Ag半球的实验表明,该方法合理且简便易行。并得出Cu在700℃、,在800℃、开始转换成以位错攀移控制的塑性变形机构为主要物质迁移机构。

The optimum technological conditions of the air sintering of aluminiumpowder were determined by sintering experiments. The experimentalinvestigation on the liquid sintering mechanisms of the Al-based mixedpowder was carried out by means of metallographic and SEM examination,etc., and the theoretical kinetic analyses were made. It was found that theeffect of magnesium-activation included 3 aspects: 1. accelerating the rateof the solution of solid into liquid; 2. reducing and destroying the surfaceoxide film of aluminium powder so as to increase the reacting areabetween solid and liquid; 3. decreasing the interface energy between thesolid and liquid, so increasing the infiltration of liquid into the interpar-ticle boundaries.

In this paper, the effect of mixed rare earth metals on the shrinkage characteristics of the ferro-based friction material is studied. The results show that during sintering, the temperature, at which the material begins to shrink, rises with the increase of the mixed rare earth content, the effect of which agrees with the formula T=αC~(1/2)+β. By means of a series of sintering experiments, the relationship between the shrinkage and time is obtained under certain sintering temperature. The...

In this paper, the effect of mixed rare earth metals on the shrinkage characteristics of the ferro-based friction material is studied. The results show that during sintering, the temperature, at which the material begins to shrink, rises with the increase of the mixed rare earth content, the effect of which agrees with the formula T=αC~(1/2)+β. By means of a series of sintering experiments, the relationship between the shrinkage and time is obtained under certain sintering temperature. The shrinkage equation of the material during sintering is suggested as ε=ε_0(1-e~(-t/τ)). It is also pointed out that before the noticeable shrinkage in the sintering, the maximum expansion of the material increases with the increasing content of the mixed rare earth.

本文研究了混合稀土金属对铁基摩擦材料烧结性质的影响。结果表明:随着混合稀土含量的增加,材料烧结时的起始收缩温度增高,其影响规律符合T=C~(a/2)+β公式。通过一系列的烧结实验,获得了保温条件下这些材料的收缩一时间曲线,并建立了材料的烧结收缩方程ε=ε_0(1-e~(-(t/τ)))。同时指出,在烧结的明显收缩前,材料的最大膨胀量随混合稀土含量成线性增大。
