Аннотация
Superplasticity characteristics of two-component and multicomponent brasses in the temperature range 525–600°C have been investigated at tension tests under the conditions of stepwise enhancement in the strain rate and when maintaining a constant strain rate of 1 × 10–3 s–1. The effective energy for activating superplastic deformation has been determined. It has been shown that brass alloyed with aluminum, tin, and iron exhibits large elongations and less porosity due to superplastic deformation. Changes in the granular structure and sample surfaces have been analyzed after deformation, and signs of grain-boundary sliding and intragrain deformation have been revealed in the alloys studied.
