master alloy

master alloy

[′mas·tər ′al‚ȯi]
(metallurgy)
An alloy of selected elements that can be added to a charge of molten metal to provide a desired composition or texture or to deoxidize the material. Also known as foundry alloy.

Electron beam melting can also be used to produce ingots of complexly alloyed titanium alloys by remelting the primary charge in the form of titanium sponge and master alloy (1).
The elaboration of the master alloy was done by melting induction in argon atmosphere of the raw materials: iron based alloys Fe-P, Fe-C, Fe-Si and high purity powders of Cr and Ga.
The key to LCB's lower cost (about 60 percent less in finished-wire form than Beta-C) is its use of an iron-molybdenum (ferromoly) master alloy. It is directly derived from the ore, which helps save cost over the pure aerospace alloys, claims Faller.
There are three approaches to formulating the basic metal powder: elemental building, master alloy, and prealloy.
It was shown in [19] that chamber electroslag remelting as the metallurgical process makes it possible, by additional alloying with an oxygen-containing master alloy, to introduce the required concentration of oxygen into titanium and ensure chemical homogeneity of the metal of the ingot.
Master alloy of the nominal composition of [Fe.sub.40.5][Co.sub.40.5][Nb.sub.7][B.sub.12] have been prepared by arc-melting from elements of 99.95% purity and amorphous ribbon 6 mm wide and about 20 [micro]m thick was produced by planar flow casting technique in vacuum at the Institute of Physics, Slovak Academy of Sciences in Bratislava.
