METHOD TO PROCESS ITEMS FROM TITANIUM OF BT1-0 GRADE

摘要

FIELD: metallurgy.;SUBSTANCE: soaking is done at heating temperature for 10-15 minutes, and cooling is done in a coolant with speed of 300°C/s, afterwards ageing is done under load at 18-25°C, stress not exceeding yield point at ageing temperature, and time required to achieve stable speed of relaxation process.;EFFECT: increased strength of titanium of BT1-0 grade in combination and higher plasticity during treatment of items from titanium BT1-0, including heating, is carried out to temperature exceeding temperature of polymorphous transformation.;1 tbl, 1 ex
