Cold crucible levitation melting of biomedical Ti-30 wt%Ta alloy.
Recently, titanium-tantalum alloys have been studied as implant materials for dental and orthopedic surgery. However, titanium and tantalum are difficult to mix by common arc melting and induction melting, because of their high melting point and the marked difference between their densities (Ti: 1,680 degrees C, 4.5 g/cm3, Ta: 2,990 degrees C, 16.6 g/cm3). Thus, the Cold Crucible Levitation Mel...
متن کاملEvolution of Continuous Melting and Decontamination Technology for Dismantled Metal by an Induction Cold Crucible
An induction cold crucible melting is one of the most promising technologies for the reuse and decontamination of the radioactively contaminated metallic materials generated during the dismantling of nuclear facilities, because the crucible ensures a long life operation without generating secondary wastes. Fundamental equipment of the Melting and Recycling of Metals by Cold Crucible (MERC) proc...
متن کامل0 ” Cold Melting ” of Invar Alloys
An anomalously strong volume magnetostriction in Invars may lead to a situation when at low temperatures the dislocation free energy becomes negative and a multiple generation of dislocations becomes possible. This generation induces a first order phase transition from the FCC crystalline to an amorphous state, and may be called " cold melting ". The possibility of the cold melting in Invars is...
متن کاملA 2-D FINITE ELEMENT MODEL SIMULATION OF THE MELTING PROCESS OF Al-Ti ALLOY IN VACUUM INDUCTION FURNACE WITH COLD CRUCIBLE (VIFCC)
The development of a numerical model for the melting process of Al-Ti alloy target material in vacuum induction furnace with cold crucible (VIFCC) was described. It is a two-dimensional computational methodology to calculate electromagnetic field, heat transfer field and fluid flow field . Based on the aid of the finite element method with the commercial software—ANSYS, a superimposition method...
متن کاملVitrification of Hlw Produced by Uranium/molybdenum Fuel Reprocessing in Cogema’s Cold Crucible Melter
The performance of the vitrification process currently used in the La Hague commercial reprocessing plants has been continuously improved during more than ten years of operation. In parallel COGEMA (industrial Operator), the French Atomic Energy Commission (CEA) and SGN (respectively COGEMA’s R&D provider and Engineering) have developed the cold crucible melter vitrification technology to obtai...
