摘要
This paper present the hot deformation behavior of the commercial 2014-T6 aluminum alloy. The alloy was thermomechanical processed for grains refining in order to improve deformation characteristics. The characteristics of deformation was investigated by using a uniaxial tensile testing at different temperatures (450, 475, 500 degrees C) and constant strain rates (5x10(-4), 1x10(-3) s(-1)). The research included determinations of flow curves characteristics, the maximum elongation to failure, ultimate tensile strength and the microstructure of the alloy. The results showed that the flow stress increased with deformation temperature decreasing and strain rate increasing and it obtained an increase in the deformation degree of the alloy. A maximum elongation to failure of 188.5 % was obtained at strain rate of 1x10(-3) s(-1) and temperature of 475 degrees C. The deformation characteristics were correlated with the results of the microstructure analysis.
