Grain Refinement after Various Thermo-Mechanical Treatments in AZ80 and ZK60 Magnesium Alloys

Original language description

The effect of thermal processing prior to severe plastic deformation by extrusion and swaging on grain refinement in ZK60 and AZ80 alloys was studied. The alloys received in direct-chill cast condition were homogenized at 415 degrees C and annealed (over-aged) at temperatures from 200 to 380 degrees C. Both the direct-hill cast and over-aged conditions were extruded at T = 300 degrees C using an extrusion ratio of ER = 19. Hot extrusion resulted in substantial grain refinement in both cases, the effectbeing stronger in the over-aged material. The extruded bars were severe plastically deformed at 250 degrees C by swaging. Swaging refined further the grain size depending on the deformation ratio (number of passes). At optimal processing conditions the grain size was 450 nm and 570 nm for the AZ80 and ZK60 alloys, respectively.
