Abstract
The invention discloses a Sr-containing Al-42Si alloy and a preparation process thereof. The Sr-containing Al-42Si aluminum alloy is formed by smelting Al-Si-Sr aluminum alloy ingots in a vacuum consumable arc furnace in a vacuum environment and sucking aluminum alloy melt into a water-cooling copper mold through a vacuum suction casting method. A preparation method of an Al-Si-Sr alloy sample comprises the steps that an appropriate number of Al-Si-Sr aluminum alloy ingots are put into a copper crucible of the vacuum consumable arc furnace; a furnace chamber is vacuumized to 1*10<4>Pa, and high-purity argon is introduced into the furnace chamber to enable the internal pressure of the furnace chamber to reach up to 40 Pa; and Al-Si-Sr alloy is molten, and alloy melt is sucked into the water-cooling copper mold. Chemical components of the Al-Si alloy comprise 0.2-0.8 wt% of Sr, 42 wt% of Si, and the balance Al. The compressive strength of the Al-Si alloy is 405-450 MPa, the hardness of the Al-Si alloy is 75-90 HBW, and the resistivity of the Al-Si alloy is 0.09-0.12 mu omega m.
