ALLOY AlZn_9 CASTED IN THE PROCESS OF RAPID SOLIDIFICATION AND CONSOLIDATED IN THE PROCESS OF PLASTIC FORMING

摘要

AlZn alloys with high Zn content have good strength properties. The basic problem in the production of the classical methods of casting alloys AlZn containing Zn above 7% is cracking of the ingots during casting. One of the methods of obtaining alloys with unusually high content of components is casting method of rapid solidification and subsequent consolidation in the process of plastic forming. This paper presents the results of the structure and properties of cast alloy AlZn_9 casted in rapid solidification process on the wheel and consolidated in the process of extrusion and continuous rotary extrusion. The study was conducted using light microscopy, scanning electron microscopy and transmission electron microscopy. Property specified in the Brinell hardness test, static compression and tensile tests.
