摘要	The hot deformation behavior of a new Al-Mn-Sc alloy was investigated by hot compression conducted at temperatures from 330 to 490 degrees C and strain rates from 0.01 to 10 s(-1). The hot deformation behavior and microstructure of the alloy were significantly affected by the deformation temperatures and strain rates. The peak flow stress decreased with increasing deformation temperatures and decreasing strain rates. According to the hot deformation behavior, the constitutive equation was established to describe the steady flow stress, and a hot processing map at 0.4 strain was obtained based on the dynamic material model and the Prasad instability standard, which can be used to evaluate the hot workability of the alloy. The developed hot processing diagram showed that the instability was more likely to occur in the higher Zener-Hollomon parameter region, and the optimal processing range was determined as 420-475 degrees C and 0.01-0.022 s(-1), in which a stable flow and a higher power dissipation were achieved.
