This inside-outside electrode consists of a metal sheath surrounding a core of fluxing and alloying compounds. |
Nevertheless, alloying can make changes in the atmospheric-corrosion rate of carbon steel. |
The corresponding loss in yield strength is compensated by alloying with vanadium, nitrogen, chromium, molybdenum, and titanium. |
As described in the previous section, alloying must be sufficient to ensure that a pearlite-free microstructure is obtained in heat treatment. |
Over two millennia these Mesopotamian cities developed the art of copper smelting, alloying bronze and, most importantly, writing. |
This is because some of the alloying elements form oxides and other compounds at the grain boundaries, embrittling the material. |
