Hardened Aluminium with Discontinuous Copper Threads
Zusammenfassung
The paper presents the influence of the quantity of discontinuous reinforced
threads on the mechanical characteristics of some samples obtained through
deformation from composite material with metallic matrix.
As a raw material for obtaining the matrix it was used aluminum powder and as
a reinforcing phase, short and long copper threads with different volumetric
percentages. The products have been plastically deformed at a final diameter of
3mm.
The presence of the copper threads dispersed in the aluminum matrix in
quantities of up to 16% copper (volumetric percentages), determines the hardening
of the composite material. Above this limit the increase in the quantity of copper is
no longer justified as it begins fragilizing the aluminum matrix.
