Assessment of Hardness in As-Cast and Homogenized Zn-Al-Cu Alloys

Abstract: A study of the effect of chemical composition on microstructure and hardness of the as-cast and homogenized Zn-Al-Cu alloys was carried out. Five different composition alloys were prepared and they were homogenized at 623 K for 648 ks in order to eliminate the dendritic structure. Rockwell ''B'' hardness was determined in the as-cast and homogenized alloys. XRD diffraction analysis of the as-cast and homogenized alloys indicated the presence of the , , ", , 0 and phases and , , ", , and 0 phases, respectively.… Show more

“…Replacing zinc with aluminium in the alloy system causes the formation of the stable θ (CuAl 2 ) with a tetragonal crystalline structure instead of the metastable ε phase, promoting a considerably higher ductility. Therefore, the purpose of this work was to investigate the effect of change in chemical composition on the microstructure, mechanical properties and hardness, in order to establish a relationship which enables us to assess the hardness in the as-cast and homogenized alloys" [9].…”
