Abstract
Copper-21%zinc-6%aluminum (Cu21Zn6Al) alloys were produced through induction casting and processed using various heat treatment methods to investigate their microstructure and mechanical behavior. Some samples were homogenized for different durations, heated for some duration, and quenched by four types of routes. The other samples were heated for different durations and quenched by a two-step quenching. One sample was aluminized to study the aluminization process of the alloy. The processed alloys were studied using optical microscope and scanning electron microscope to explore the microstructure. A lamellar microstructure was observed. The Vickers hardness data were obtained using a microhardness tester. The results show that the grain size increases with the increase of the homogenization duration; the sample quenched to ice directly experienced the fastest cooling rate and thus has the smallest grain size compared with the other three types of quenching routes; the sample experienced longer homogenization duration has lower hardness value and the lowering rate of hardness value levels off with the increase of homogenization duration; the increase of heating temperature from 900 to 950 °C resulted in the decrease of hardness value; and the aluminization process realized an aluminized protection layer on the sample surface.
