  The general objective
  The main project objective is the development and homologation of a refractory austenitic steel brand, high alloyed with 32% Cr and 20% Ni and stabilized with titanium and of a casting technology in order to obtain parts with applications in various fields of the industry niche.
  
  Project Summary
  The "Corrosion resistant X10 NiCrAlTi 32 20 refractory alloy" project, proposed by an inter-disciplinary team composed of Coordinator IMA SC METAV (SMEs) and P1 - UPB (CD), aims to achieve a new steel brand of refractory austenitic alloys grade, X10NiCrAlTi 32-20, with high corrosion resistance and high temperatures resistance, similar with high alloyed nickel alloys (INCOLOY 800).
  
  

  The new alloy is intended for semi-products, components or spare parts execution with high resistance at high temperatures and corrosion in areas such as chemical, gas and petrochemical, aeronautics, food and pharmaceutical industries.

  The development of the elaboration-casting technology for this high alloyed alloy with 32% Cr and 20% Ni stabilized with titanium, will bring economic benefits and prestige for the applicant (IMA METAV), one of the few special alloy casting parts producer in Romania, with a necessary production infrastructure (VIM + VAR).

  Since the alloy machining main problem is the microstructural stability loss by hot-cracking, the project foresees original elements for the microstructural consolidation, respectively Ti, Al and lanthanides (Ce) microalloying for granulation finishing and chromium carbides precipitation constraint, which determine the alloy brittleness at elevated temperatures. To avoid additional hardening and to keep the metal matrix stiffness, the cumulated microalloying elements will be up to 0.8% (Al+Ti+Ce).

  The ownership right distribution on the results will be established and agree between partners in the collaboration agreement, at the project start-up. The obtained scientific and technical results through the project deployment will be disseminated on a large scale by participating at scientific and technical manifestations, publications and web page.
  
  Project implementation period: 24 months
