Effects of Alloying Elements on Notch toghness of Basic Weld Metals (Reponrt 3)

Effects of Mangnmense, Nickel, Chromium, Molybdenum, and Vanadium in the Silicon Deoxidation

Abstract

The effect of five alloying elements on notch toughness of basic weldmetals were investigated. By manual are welding the all weld metals were obtained which composions were varied by systematic addition of alloy elements. Manganese and nickel decreases tramsition temperature at a rate of 20°C and 15°C per 1 percent, but vanadiam raises transition temperature 20°C per 0.1 percent.
Molybdenum does not change transition temmperature up to 0.15 percent, but by farther addition it raises transition temperature at a rate of 6°C per 0.1 percent.
Chromium raises transition temperature several degrees up to 0.4 percent, but decreases it by further addition of chromium.
