via solid solution hardening and precipitation hardening of a face-centered cubic (fcc) Ni matrix phase. The size, morphology and distribution of precipitates determine the properties of the material.... Coarsening and dissolution mechanisms at 1120°C are discussed. Precipitates are found to grow up to a critical size in coherent and cubical morphology, beyond which dissolution sets in. 关键词:precipitation......
during homogenization. Furthermore, the Ce addition introduces changes in the precipitation process and consequently in the age-hardening behavior of the alloy. Microstructural measurements reveal..., it can be concluded that Mg(Zn,Cu,Al)2 may transform into Al2CuMg phase during homogenization, which is in agreement with the results in Refs. [12-13]. 3.2 Hardness curves The precipitation hardening......
