PROSPECTIVE MODIFIERS FOR ALUMINUM-BASED ALLOYS
Abstract
Compositions of master-alloys on the basis of systems Al-Zr, Al-Cu-Zr, Al-Cu-Ni-Zr for modification of aluminium based alloys have been developed. The samples of these materials in microcrystal state in the form of powders and extruded rods have been obtained and investigated. The possibility of obtaining in their structure of metastable intermetallid Al3Zr, which is an active modifier of aluminium alloys have been shown. On the example of the modification of high-strength aluminium alloy B95 the effectiveness of the use of the developed master alloys have been demonstrated.
