摘要：aluminum alloy, suitable for rapid cooling from a legierungsbestandteilensaturated melt, which is 2 to 5.5 wt.% cr, 2 to 5.5% by weight of al and v, any furtheradditions that mo, zr, ti or fe, individually or in combination, to a total value of high ns 1wt.%, contains, in such a way that the total content of all alloying elements up to 10%.-%.the simultaneous occurrence of the phases al\₁\₃cr\₂ and al\₁\₀vin solid solution and a hardening dispersoid of not more than 0.1 micrometerpartikeldurch\messer effect and thermal stability at high warmfestigkeit goodductility and toughness of the material.the comparatively lower vickers hardness of therapidly solidified alloys primarily from an average of about 130 (hv) provides goodworkability of the powder. after the heat treatment, the werk\st\ückvickersh\ärten of up to approximately 200 (hv)
