FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used in hot die forging of articles from, primarily, aluminium-magnesium alloys. Workpiece is heated to 240…260°C with isothermal curing at said temperature for 0.5…2 h. Then, die forging is performed at the rate of 5·10-3…5·10-2 s-1 in molds heated to 350…400°C.
EFFECT: improved mechanical properties, higher quality of die forging.
