Abstract

The aim of this research is to investigate INTERFACE evolution during CENTRIFUGAL CASTING of Al-Cu bimetal composite. In this work, 100 grams aluminum melt was cast into a 150°C preheated Cu cylindrical bush rotating at 700, 900, 1500, and 3000 rotation per minute (rpm) inserted in a vertical CENTRIFUGAL CASTING (VCC) machine. Obtained samples were studied using optical microscope (OM) and scanning electron microscopy (SEM) equipped with EDS system and also microhardness test on various available phases. Centrifugal force, due to the rotational speed, leads to increase in the cooling rate. Cooling rate increment not only causes thinning the INTERFACE but also with increasing nucleation sites leads to modify the resulted microstructure. EDS results showed that the achieved INTERFACE consisted of four discrete layers from the Cu side, including Cu2Al, AlCu, Al2Cu continuous layers, Al2Cu precipitates scattering in anomalous eutectic structures and finally a-Al/Al3Cu anomalous eutectic structure near the Al side. Micro hardness measurements showed that hardness of various presented phases decreases in both Al and Cu side but have a maximum pick, more than 500 Vickers, near to Cu bush as a result of INTERMETALLIC COMPOUND formation.
