The res lts show: p nch sq eeze casting res lts in converse flow of alloy liq id, which improves solidification condition of ZA43 alloy and avails to eliminate porosity, and makes less press re loss d ring the process, w hile pl nger sq eeze cast- ing also enhances flow of alloy liq id, b t there is no macro-flow , and press re loss is higher. To achieve ZA43 alloy castings with high plasticity , specific press re of pl nger sq eeze casting is m ch higher than that of p nch sq eez casting Key Wor s: Squeeze Casting, ZA43 Alloy, Mechanical Properties, Specific Pressure [1] 　　,,。 。, [2] , 。 ,,。 ,、、, ZA43, 。 , , 。 * 　,, 1945,,, 58( 110023)　　: 1999- 09- 05 。,, 。 ;,。 , , 。 , 150℃。 ,、 4　结　论 。,, 、, ,。, ,,, 。 。 720～ 740℃ ,, 。 。 、 ( 7) 　, , 。 、。 , 5% 200～ 300 95% , 　　　 。 , 1　..: , 1981. 70
