ABSTRACT The effect of sintering variables on the zinc loss during sintering of brass was investigated. Zinc loss, evident through mass change, starts during heating of the powder at approximately 700°C. By supersolidus liquid phase sintering of the cold-pressed brass powder, the maximum amount of zinc loss occurred at lower temperatures and prolonged sintering times. At higher temperatures, especially near the zinc boiling point, the rate of zinc loss from the surface is surprisingly moderate since closing of the pores causes zinc to be trapped in the samples. At lower temperatures, in contrast, when the pores in the surface are open and there is also a lower volume fraction of liquid phase, zinc can easily escape from the samples. Generally, it was thus concluded that during sintering, zinc loss depends more strongly on the pore connectivity and the specific surface than just on the nominal vapour pressure.

α黄铜超固相液相烧结过程中孔隙粗化与质量损失的关系

摘要研究了烧结变量对黄铜烧结过程中锌损失的影响。在粉末加热至 700°C 的过程中，锌损失（通过质量变化明显）开始。通过冷压黄铜粉末的超固相液相烧结，在较低温度和较长烧结时间下发生最大量的锌损失。在更高的温度下，尤其是在锌沸点附近，锌从表面流失的速度出人意料地适中，因为孔的关闭导致锌被困在样品中。相反，在较低的温度下，当表面的孔是开放的并且液相的体积分数也较低时，锌很容易从样品中逸出。总的来说，由此得出的结论是，在烧结过程中，
