The effects of iron, phosphorus, titanium and zirconium as the added elements on the grain growth in high purity brass have been reported in our previous papers. In the present paper, the effects of a small amount of manganese, magnesium and chromium were investigated after annealing for 1 hour at various temperatures or rapid short time heating at higher temperatures above 700°C. In the case of the ordinary annealing, manganese and magnesium are not much effective for grain-size control of brass when present in quantities less than 0.5%, but at higher annealing temperatures they have a restrictive effect on the grain growth. On the other hand, a small amount of chromium is very effective in retarding the grain growth at ordinary annealing when present 0.009% or more, but at higher annealing temperatures, the restrictive effect of chromium was found to be reduced.
