- Аннотация: Phase diagram of the Al-Cu-Ce system is investigated in the region of the quasi-binary join Al-Al8CeCu4. The parameter of the eutectic reaction L -→ (Al) × CeCu4Al8 are found: T = 610°C; composition 14% Cu and 7% Ce. This eutectic has a dispersed structure, and the ternary compounds, which is involved in the eutectic, is capable to fragmentation and spheroidism in the course of heating starting from 540°C. It is shown that the region of optimal compositions of alloys based on the eutectic (Al) + CeCu4Al8 lies in narrow limits. This is caused by the fact that an abrupt decrease of the solidus and, as a consequence, significant broadening of the crystallization range occurs at a relatively small deviation from the ratio Cu: Ce = 2. © Allerton Press, Inc., 2007.
