摘要
The invention relates to metallurgy. The aim - increase of suitable vkoda by semi predotvratesh rupture during the final stretch deformation zhet1em and stabilization of the mechanical properties. The method includes a preliminary straightening zhemshem stretching the quenched semi-finished product, prior artificial aging, final stretch deformation Jette velichk- us to tensile stress 6 udovle.t- BopmouDix condition L 6 g de desired value semifinished yield after final artificial aging; increase the minimum possible values of the yield strength in the final artificial aging and aging okonchatapnoe iskusstveinoe. . Izobretershe provides povshgoiie vghoda of suitable semifinished on Yu- 20% and allows narrow spacing variations of mechanical properties semifinished i, a- to 1.0 kgf / mm b ", - up to 1.9 KrcArMS ./ -do2,0%. 27a6p (D (LS
