Tungsten hardening element

Cobalt in small amounts is an essential element associated with vitamin B12, but at high levels can be toxic. There are no daily recommended intake levels for cobalt. Intestinal bacteria use cobalt to produce cobalamin, which in turn is an essential component of vitamin B12. Industrially, cobalt is used in pigments, permanent magnets, and as an alloy to harden metals as in tungsten carbide blades or drills. [Pg.127]

By shifting the eutectoid point to lower carbon concentrations, tungsten increases the amount of undissolved and excess carbide in the hardened steel. Tungsten is a carbideforming element and binds the carbon to form straight tungsten carbide or combines with... [Pg.307]

Alloys are prepared by mechanical alloying by seahng powdered elemental components in a hardened steel or tungsten carbide vial with several hardened steel balls. The impact of the balls, when shaken by a high energy ball mill. [Pg.208]

Solid solution hardening of the y matrix resulting from the coherency strains or stiffening effect or larger atom elements such as chromium, molybdenum, and tungsten. [Pg.494]
