| description | •We study of the Al-10 at.% Y alloy structure during rapid cooling at pressure of 9 GPa.•Using high pressure, we have provided a dense homogeneous alloy structure.•We obtained abnormally Al(Y)-supersaturated solid solution and metastable eutectic.
Using the methods of durametry, X-ray structural analysis, optical and electronic microscopy, we have compared the structures of the Al90Y10 hypereutectic alloy (hereinafter at.% is given) obtained at the atmospheric pressure and that produced with quick cooling under pressure of 9 GPa. It has been demonstrated that, in both cases, the crystalline phases of α-Al and Al3Y get formed.11Low-temperature Al3Y phase – at the atmospheric pressure; high-temperature metastable Al3Y* phase – hardening under high pressure. Using high pressure, we have provided a dense homogeneous alloy structure with abnormally α-Al-supersaturated solid solution and finely divided aluminides in metastable eutectics with high hardness. |
