Abstract:
The hypereuteclie Al-Si alloys were modified with Al-P master alloy and evaluation of machinabilitby comparing the tool life and surface quality at room temperature. The experimental results show that after AlP master alloy modilication, primary silieon becomes small, seattered and round passivation, the tool life is1.75 times than before , frietion-time curve becomes smooth and weight loss becomes small, and those resultsshow that materials hard particles for tool wear beeome smaller and modifieation improves machinability.
