The warm and hot deformation behavior of a 6060 aluminum alloy was investigated through compression tests conducted at temperatures ranging from 100 °C to 400 °C (homologous temperature range of 0.41–0.75) and strain rates of 0.001 and 0.1 s−1. The flow stresses were correlated with strain rate and temperature using a hyperbolic sine equation, and the activation energy was calculated for both deformation regimes. The modeling parameters were linked to the active plastic deformation mechanisms: strain hardening in the warm regime and dynamic recrystallization in the hot regime. A strong correlation between the experimental and calculated data was observed when the equation was applied separately to the stresses measured in the warm and hot temperature ranges.

Abstract
The warm and hot deformation behavior of a 6060 aluminum alloy was investigated through compression tests conducted at temperatures ranging from 100 °C to 400 °C (homologous temperature range of 0.41–0.75) and strain rates of 0.001 and 0.1 s−1. The flow stresses were correlated with strain rate and temperature using a hyperbolic sine equation, and the activation energy was calculated for both deformation regimes. The modeling parameters were linked to the active plastic deformation mechanisms: strain hardening in the warm regime and dynamic recrystallization in the hot regime. A strong correlation between the experimental and calculated data was observed when the equation was applied separately to the stresses measured in the warm and hot temperature ranges.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
