The influence of heat treatment modes on VT3-1 alloy structure to increase ductility before pressure operation
The influence of the chemical composition and thermal treatment regimes on the structure and properties of parts made of BT 3-1 alloy is considered in the article. It is found that an increase in the content of chromium and molybdenum to the upper limit controlled by GOST causes decrease in ductility and increase in the strength of the alloy. A correction of the resulting defect by conducting repeated annealing with a lowered temperature is proposed.
