Abstract

In this study, the influence of the variable content of Al, Ni, Fe on the grain refining and the change of mechanical properties of aluminium bronze cast into iron ingot mould was investigated. The ingots were tested for susceptibility to cold plastic working in the rolling process. It was shown that a small amount of iron (0,8 wt. %) influenced a significant level of grain refining and improvement of mechanical properties. For alloys with an increased content of Al, Fe and Ni, the maximum value of the true strain of 0,36 was achieved in the cold rolling process. The possibility of achieving similar mechanical properties for alloy with reduced content of alloying elements was demonstrated after applying the true strain of 0,61.
