Moreover,Al_2Er phase is face centered cubic structure,which is different with the structure of Mg(Hexagonal Close-Packed).
但是过量的Zr将与合金中的Al反应生成Al_3Zr沉淀相，消耗了合金中的Al元素，减弱了Al对镁合金的细化、强化作用，而且由于Al_3Zr与镁基体没有共格关系，不能起到细化晶粒的作用，合金组织粗化。

The modification of the Gladman's model may then be proposed by the comparison of different models of grain coarsening with assumption of uneven in convexo-concave interface along grains. The modified Gladman's expression is given as: R_o =πr/3f_v(3/-2/Z) that may fairly predict the actual grain size observed.

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.
结果表明：微波烧结升温速度快，周期短，能促进W-Cu材料的致密化；在适当条件下，微波烧结能获得相对密度达99.8%的W-Cu样品；微波烧结能改善W-Cu样品中两相分布的均匀性和W晶粒尺寸的一致性，但引起W晶粒的快速长大；Fe烧结助剂导致W-Cu材料显微组织均匀性变差，并引起晶粒进一步粗化；微波烧结技术能够应用于W-Cu材料的制备，在缩短生产周期、降低生产成本方面具有潜在优势。

Densification：致密化
因为在烧结过程中,颗粒粗化(Coarsening)、素坯致密化(Densification)、晶粒生长(Grain Growth)三者的活化能不相同,--其中QI>Qd>Q. 因此这三者的动力学过程与温度有不同的依赖关系,即颗粒粗化、素坯致密化、晶粒生长三者主要在不同的温度区间进行,
