Wear-resistant sintered aluminum alloy and method for producing the same |
摘要 |
<p>The Al-Si sintered alloy having good mechanical strength and elongation and is especially excellent in wear resistance, and a method for producing the same. The sintered alloy consists of 2.4-23.5% Si, 2-5% Cu, 0.2-1.5% Mg, 0.01-1% of transition metals and the balance of aluminum and unavoidable impurities, and has a dapple grain structure of an Al-solid solution phase and an Al-Si alloy phase containing dispersed pro-eutectic Si crystals having a maximum diameter of 5-60 mu m either in the whole body or in the surface contact portion, and the area ratio of the Al-solid solution phase in the grain structure is in the range of 20-80%.</p> |
