在熟化过程中，反应溶液的pH值和反应温度的升高均加快熟化过程溶解-再结晶速度，使熟化过程进行得更充分。

The activation effect is proper when the Cu component is low, but it becomes weaker as Cu increases. This is probably due to that there is not dissolution and reprecipitation of W in liquid Cu during the process of liquid phase sintering.

含Cu量较少的粉末烧结W—Cu合金有一定的活化效果，但在含Cu量较高时，活化效果不十分明显，可能与烧结过程W不能在液相Cu中产生溶解—析出有关。

From the research, it is concluded that the sintering mechanism of AlN with Y 2O 3 is the solution reprecipitation process controlled by the rate of boundary reaction.

用最小二乘法回归分析实验数据，依据现有的烧结理论研究后表明，添加Y2O3的AlN材料的中后期烧结机理为相界反应速率控制的溶解—淀析过

It was observed in the Cr-Ni-Mo steels that the intergranular ductile fracture is caused by the reprecipitation of MnS particles in the steel with ordinary S content, and the overheating is also performed by the repreeipitation of AlN or VC particles along the prior austenite grain boundaries in one containing low S. Thus, a proposal seems to be made that the mechanism of overheating of Cr-Ni-Mo steels is related to the solution and reprecipitation of MnS, AlN or VC particles along the prior austenite grain boundaries.

MnS粒子的重新析出使普通硫含量的Cr-Ni-Mo钢发生沿晶延性破断，而AlN或VC粒子在高温奥氏体晶界的重新析出也能使低硫的Cr-Ni-Mo钢过热。

The sample which has retrogressive phenomenon precipitates the secondary phase during re-ageing treatment subsequently, and the reprecipitation sequence is due to the grain size caused by severe plastic deformation. There is a critical grain size below which the reprecipitation sequence changes, the heterogeneous precipitation of phase at grain boundaries would suppress precipitation of metastable phases such as GP zones and η′ phase.

强变形导致回归后的合金在再时效处理时可再次沉淀析出第二相粒子，但析出相的析出顺序与强变形后合金的晶粒尺有相关，当晶粒细化到某一临界尺寸以下时，析出顺序发生改变，非均匀形核的平衡相可抑制GP区、η′亚稳相等前期粒子的析出。
