FIELD: metallurgy.
SUBSTANCE: work pieces out of lead alpha+beta brass are heated above temperature of transition of alpha+beta structure into a beta-phase, but 100°C below solidus temperature; further work-pieces are transferred into container of press and are pressed.
EFFECT: increased homogeneity of metal structure and distribution of mechanical properties along length of item, reduced wastes of production.
