CAST SECTION FROM BRASS FOR MANUFACTURING OF RINGS OF SYNCHRONISER Russian patent published in 2010 - IPC C22C9/04 

FIELD: metallurgy.

SUBSTANCE: there is proposed cast section from brass for manufacturing of rings of synchronisers. Brass contains additions of manganese, aluminium, iron, silicon, lead and titanium. Structure consists of α-phase, biphase areas (α+β')-mixture of phases and silicides of manganese and iron (Fe,Mn)₅Si₃. Content of titanium in brass is 0.01 - 0.07 wt % at content of titanium in biphase areas (α+β')- mixture of phases 0.04 - 0.18 wt %, and in silicides of manganese and iron (Fe,Mn)₅Si₃ - 0.06 - 0.26 wt %.

EFFECT: increased production strength and plasticity of cast sections.
