Abstract

Hot compression tests were carried out to study the deformation behaviors of a lead-free machinable brass using Gleeble-1500 thermal simulator in the temperature range of 823–973K and the strain rate range of 0.01–10 s−1. The results show that the flow behavior of the lead-free machinable brass is strongly influenced by strain rate and temperature, and the flow stress increases with increasing strain rate and decreasing temperature. The constitutive equations incorporating the effects of strain rate and temperature have been established to model the hot deformation behavior of this alloy. The reliability of the developed constitutive model was demonstrated by the mean percentage error of 10.82 % and the correlation coefficient of 0.98. Moreover, the flow stability/instability of the lead-free machinable brass was carefully investigated on the basis of dynamic material modeling approach. It was found that plastic deformation was stable for processing conditions in which the strain rate range was 1–10 s−1 within the temperature range of 823–923 K.
