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 240Ç260C with isothermal curing at said temperature for 0.5Ç2 h. Then, die forging is performed at the rate of 510-3Ç510-2 s-1 in molds heated to 350Ç400C. ^ EFFECT: improved mechanical properties, higher quality of die forging. ^ 1 tbl, 1 ex |
