Effect of Inoculant Alloy Selection and Particle Size on …

The process of isomorphic inoculation relies on precise selection of inoculant alloys for a given system. Three alloys, Ti-10Al-25Nb, Ti-25Al-10Ta, and Ti-47Ta (at %) were selected as potential isomorphic inoculants for a Ti-46Al alloy.

Crucible - Wikipedia

This process involves the coination of a metal and a gas to produce an alloy (Zwicker et al. 1985: p107). Brass is made by mixing solid copper metal with zinc oxide or carbonate which comes in the form of calamine or smithsonite (Rehren 2003: p209).

20/9/2018· Often, late inoculation is used like a patch in the process to solve anomalies previously created and restoring acceptable nucleation levels.

Inoculations | Article about inoculations by The Free …

Inoculation is used in the production of cast iron and silumin ingots. Inoculation is distinct from microalloying, in which an increase in the quantity of additive leads to ordinary alloying (without a clear boundary between the effects produced).
