An initial rapidly solidified powder alloy was prepared by the pressure nitrogen melt atomisation. Subsequently, the granulometric powder fraction of less than 45 lm was hot-extruded. According to X-ray diffraction and transmission electron microscopy observation, the compact material is composed of a-Al grains and spheroids of intermetallic phases. The a-Al grains of the compacted material are recrystallized and neither residual stress nor texture were observed. The values of ultimate tensile strength and yield strength of the investigated material were similar to the values for conventional Al-based alloys. Dependences of ultimate tensile strength and yield strength on temperature were also measured. Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2011
