Friction Consolidation and Extrusion: Exploiting a New Severe Plastic Deformation Process

Abstract

Friction consolidation and friction extrusion were invented in the early 1990’s at TWI. However, these two processes have only recently gained renewed attention. The severe shear strains imparted to materials subjected to these processes may enable the creation of extrusions and other product forms with exceptional properties and potentially reduce the energy required for the manufacture of certain high value added metallic materials. In this presentation some early successes and remaining challenges in this field will be discussed.

Tony Reynolds is the Frank B. Herty Bicentennial Chair in Engineering in the Department of Mechanical Engineering at the University of South Carolina.   Professor Reynolds received his PhD in Materials Science from The University of Virginia in 1990 and for the past twenty years his research group has been working in the area of friction stir welding and processing of metals. Since 2010 the Reynolds research group has been studying and developing the friction extrusion process.

Latest advances in numerical process simulation

Abstract

The industry must demonstrate the ability to develop forming processes using increasingly diverse and complex materials, in a well-controlled manner and applicable to different economic sectors such as aerospace, nuclear, defense and energy. To meet these requirements, processes evolve and new ones appear. This serves two purposes:

  • better control of the material flow and energy and giving a global vision of the chain transformation of materials transformation (forming, heat treatment, welding,…)
  • but above all, taking into account the effects of the inheritance of properties, structures, defects from upstream to downstream processes.

Multi-physics, multi-scale and multi-phase modeling are a key driver in such actions. We will give examples of numerical challenges that have for missions to meet these metal forming industries industry needs in friction welding, additive manufacturing and heat treatment.

Elisabeth MASSONI is the director of CEMEF (Center for the Materials Forming), one of the eighteen research centers of MINES ParisTech. Approximately 160 people work at the CEMEF, of which 60 are permanent (50% are teaching researchers) and 70 PhD students. The research activities, mainly carried out in close collaboration with the industrial sector, are multidisciplinary and concern the broad field of materials science, manufacturing, materials elaboration and numerical codes development (multi-scale and multi-physics). Elisabeth MASSONI is personally interested in the numerical simulation of metal forming and heat treatment processes. She pays particular attention to the development of complex behavior models. Its activities have resulted in more than fifty publications in peer-reviewed journals and in the defense of 26 doctoral thesis conducted in close collaboration with industry in various economic sectors (automobile, aeronautics, etc.) .

Effect Of The Elongational Flow (Hot And Cold Drawing) On The Morphology And Properties Of Polymer Systems

Abstract

Polymer systems subjected to elongational flow during hot and/or cold drawing undergo relevant changes in their morphology and properties because of the orientation achieved during processing. In particular, a dramatic increase of the elastic modulus and a drastic decrease of the elongation at break is observed. These effects become more relevant for biphasic systems like polymer blends and polymer nanocomposites. A review of these effects will be presented.

Body in White evolution for Luxury Cars: trends in shapes and materials.

Abstract

 Design standards trends in automotive is more evident and some year ahead in the Luxury Cars field where Fontana Group is largely involved. The change is driven by two main aspects: the first is aesthetical: a luxury car has to amaze. The second reason is both ecological (fuel saving, C02 reduction and material recycling) and technical (performance increasing, mainly on sport cars). The result is the exponential growing of aluminum alloys usage in the automotive.
