Structure and mechanical behavior of Al-[Al.sub.4][C.sub.3] composites

Results obtained from an x-ray phase analysis and mechanical tests on compression of hot-pressed Al-[Al.sub.4][C.sub.3] composites with 5 or 10 wt.% C added to the initial powder mixture are presented. It is shown that the higher is the amount of aluminum carbide formed under hot pressing, the highe...

Zusammenfassung:Results obtained from an x-ray phase analysis and mechanical tests on compression of hot-pressed Al-[Al.sub.4][C.sub.3] composites with 5 or 10 wt.% C added to the initial powder mixture are presented. It is shown that the higher is the amount of aluminum carbide formed under hot pressing, the higher are the yield stress and the effective elastic modulus of the composite. Keywords: composite material, hot pressing, aluminum, carbon, aluminum carbide, strength.
