对Co-11.0Ge-5.7W （at.%）三元合金进行了显微组织研究。在1173 K退火后，合金中有细小的立方相析出，析出相的晶体结构为L1(2)组织，成分为Co-12.6Ge-8.2W （at.%）。该相的溶剂温度约为1180k。由于在Co-W和Co-Ge二元体系中尚未发现稳定的L1(2)相，因此该三元化合物是一种新的L1(2)相，命名为γ′-Co-3（Ge，W）。(c) 2006材料学报Elsevier Ltd.出版。版权所有。
Microstructural investigation of the Co-11.0Ge-5.7W (at.%) ternary alloy was conducted. Fine cuboidal precipitates were observed in this alloy annealed at 1173 K and the crystal structure of the precipitate phase was identified as an L1(2) structure with a composition of Co-12.6Ge-8.2W (at.%). The solvus temperature of this phase was about 1180 K. Since a stable L1(2) phase has not been reported in the Co-W and Co-Ge binary systems, this ternary compound is a new L1(2) phase designated as gamma'-Co-3(Ge,W). (c) 2006 Acta Materialia Inc.
