Mechanical Properties of Al-Al4C3 Composite Produced by Mechanical Alloying

Popis výsledku v původním jazyce

The aim of this paper was to study the influence of different input materials and methods of treatment on the microstructure, mechanical properties and fracture of dispersion strengthened aluminium alloys in the Al-Al4C3 system. It was proved that the transformation efficiency of carbon to Al4C3 by heat treatment of aluminium with the porous furnace black and electrographite is higher than that of the hard cracked graphite. The size of Al4C3 dispersed phase was measured by TEM on thin foil and it was constant and as small as 30 nm. Subgrain size measured in the range of 100 grains in thin foils depended on the carbon type, as well. It ranged from 0.3 to 0.7 ?m. The temperature dependence of ductility, and reduction of area in the temperature range of 623 ? 723 K and strain rate of 10-1 s-1, indicated a considerable increase of properties. In a case when the volume fraction of Al4C3 changes from lower to higher, the grain rotation mechanism dominates instead of the grain boundary slidin
