        摘要：The compactness of ZL101 and ZL102 alloys has been studied, and the effects of some modifiers, such as Na,Sr,Sb and P, on the compactness of alloys have been tested. Experimental results show that Na and Sr make the alloy compactness reduce, but P proves the contrary. The compactness of alloys is related to effects of the modifiers on the solidification temperature range of alloys.

        摘要：The friction and wear properties of 2 kinds of high strength Zn Al alloys and 3 kinds of Cu alloys are demonstrated. Under different lood and rotative velocity, the friction factor and abrasion wear of the alloys and their coupling samples are given. The results show that the Zn Al alloy is an excellent anti friction meterial applied to heavy load and low rotation.

        摘要：The mechanism of forming the gas hole defect in the M17F superalloy investment casting for turbine blade was studied. The main affecting factors are that: C left on ceramic core after prefiring shell, Ta, a alloying element, increased the chemical activity of the liquid alloy, and the amorphous SiO 2, a zircon resolvent, helped to bring about the action produced gasses.

        摘要：Using pore free die casting, the castings with porosity free, heat treatable and weldable features are given. Mechanical properties of Al casting are improved significantly: Tensile strength and elongation as cast are increased by 30% and 150%￣200% separately. Tensile strength, yield strength and impact toughness by heat treatment are increased by 30%, 100% and more than 100% separately. Many Al or Mg alloy die castings, such as the auto wheel, the brake cylinder, the hydraulic valve, the actuator body and the heat exchanger, have been produced. Being made in pore free die casting and heat treated by T6, Al Si12CuFe alloy wheel has follow properties: σ b=276 MPa, σ s=221 MPa, δ =7.0% and a similar fatigue characteristic to the rolled 5454 Al wheel.

        摘要：The dimension stability of eutectic and hyper eutectic Al Si alloy pistons in aging at 200 ℃ over a long period is investigated. It is found that the diameter in the piston crown is increased non reversibely with prolonging of aging time. The dimension stability of hyper eutectic Al Si alloy piston is higher than that of eutectic Al Si alloy piston. The crown diameter of eutectic Al Si alloy piston has increased suddenly in twice, but the hyper eutectic Al Si alloy piston only once.
