Recycling, melting and casting high quality metals

Advanced foundry

Improving liquid metal processes is fundamental to increase the performance of metallic products while decreasing their environmental impact.

IRT M2P works on multiple aspects of liquid metallurgy and pyrometallurgy: melting and casting under a protective atmosphere of recycled materials and new alloys while maintaining high purity ; analysis and characterization of as-cast semi-products ; various forming techniques such as forging, rolling and also gas atomization ; near-net-shape processes in order to reduce material consumption. Through an improved understanding at semi-industrial scale of the links between process parameters and product properties, industry can deploy new and improved materials and processes more quickly and efficiently.


Expertise & Services

Improving the recycling of metallic materials

  • Link between scrap properties and as-cast metal quality
  • Development of pyrometallurgical recycling processes that maintain metal quality

Melting, casting and atomization of any alloy under a protective atmosphere to ensure quality: Al, Fe, Ni, Cu, superalloys and reactive or refractory metals (Ti, Nb, Ta, etc.)

  • Chemical analysis during melting
  • Liquid metal/slag equilibrium measurements
  • Studies on the kinetics of inclusion dissolution, metal cleanliness and inclusion/fatigue relationships

Wide variety of casting platforms: ingot, near-net-shape by sand or investment casting

Refractory/liquid metal corrosion studies

Access to various forming techniques such as forging, thixoforging, rolling or gas atomization

Small series or prototype production

Technical support for evaluating the industrial relevance of new melting and forming techniques

Analysis and characterization of liquid metal, as-cast or formed products and final products



Our processes allow the production of any type of alloy in various forms and quantities between 5 and 350 kg. In addition to the quality of the metals produced, the processes are 100% electric, allow the use of recycled materials and do not release pollutants into the atmosphere.

Induction melting
Melting under vacuum or protective atmosphere in refractory or cold-hearth crucibles
Various semi-products: ingots, bars and complex shapes including near-net-shape
Sensors in the furnace and moulds for data collection and modeling
High purity and low inclusion metals

Plasma arc melting
Cold-hearth refiner for melting/remelting refractory or reactive metals
Multi-parts crucible in order to better eliminate inclusions and improve final ingot cleanliness
Controlled atmosphere melting (He or Ar) at near-atmospheric pressure in order to avoid evaporation of volatile alloying elements and better control final chemistry
Flexible charging system that allows the remelting or recycling of ingots, various revert/turnings, virgin raw materials and/or metallic powders
