AL LM6 hollow cylinder fabricated using centrifugal casting

The main purpose of this study was to investigate the silicon (Si) particles distribution of Al LM6 cylinder produced by centrifugal casting method. Al LM6 cylinder fabrication started by melting Al LM6 ingots. The melt is then poured into a rotating mould with constant speed of 1700 rpm (100 times...
