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 first step to get nanocrystalline alloys was to obtain a master alloy in form of bars, with an optimal chemical composition.
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.
Molders say there is ready availability only of pure iron and nickel powders for both the elemental building and master alloy approaches, but there are still shortages of fully formulated stainless- or tool-steel powders (or other complex alloys) for the prealloy approach, which most molders would greatly prefer.
