METHOD FOR PRODUCTION OF BIMETAL STRIPS, SHEETS AND BANDS MADE OF METAL POWDERS

摘要

The invention relates to powder metallurgy. A method for production of bimetal strips, sheets and bands of metal powders includes rolling powders of different composition in rolls of the same diameters, sintering the resulting product and further compacting rolling the product, and compacting rolling is carried out in the rolling rolls of different diameters with a ratio of the diameter of greater roll to the diameter of smaller roll 1.1-1.3 with relative reduction rate 0.45-0.5. Effect: increased quality of products due to lowering nonflatness thereof.
