查询词典 sintering

The challenges of these material are screen printing and sintering process.

It has been found that during the spark plasma sintering process, under the condition of large current, short sintering time and lower sintering temperature, the metastable icosahedron quasicrystal phase in primary powder particles is kept. And the strong discharge plasma among particles can decompose or break the oxide film on the primary powder's surface, resulting in the increment of their combination strength. So the as-prepared bulk alloy possesses high density and ultra-high strength.

The results show that the vertical sintering speed changes notably with the proceeding of sintering process. After ignition and thermal retardation the bed permeability deteriorates and the sintering speed decreases notably because of the progress of physical chemistry reaction, formation and broaden of combustion zone, and formation of overwet zone. In about 25 min, the over wet zone vanishes, so the bed permeability meliorates and the speed arises rapidly.

结果表明：垂直烧结速度并非固定不变，而是随着烧结过程的逐步进行发生显著变化；点火保温后，随烧结物理化学反应的进行，燃烧带逐渐形成并变宽且产生过湿现象，导致料层的透气性显著变差，烧结速度显著下降，直至约25 min后过湿层完全消失，透气性变好，烧结速度迅速上升。

The experimental results show that microwave sintering promotes the densification of green compacts with higher heating rate and reduced sintering cycle. The sintered relative density of 99.8% can be achieved during microwave processing under appropriate conditions. In addition, microwave sintering improves the uniformity and homogenization of W grain size, and yet leads to growth of W grain. Fe sintering aid degrades the microstructure uniformity and further coarsens W grains. The present investigation demonstrates the feasibility of applying microwave sintering technique to consolidate W-Cu composites and its promising outlook in reducing production cycle and cost.
