TITANIUM 2012 Aerospace Materials & Processes

Aerospace Materials and Processes, a speaker panel at TITANIUM 2012, the 28th annual conference and exhibition, will examine titanium manufacturing techniques and alloy selection, both of which are critical for demanding aerospace applications. Titanium Metals Corp. (TIMET), Dallas, will sponsor the panel, which will be moderated by Dr. Yoji Kosaka, senior manager, U.S. research, at TIMET's Henderson Technical Laboratory, Henderson NV.

A paper by Dr. Daniel G. Sanders, senior technical fellow, Boeing Research and Technology for Chicago-based Boeing Co., will examine promising new titanium alloys and production methods now under development at Boeing, which may offer advantages over the existing alloy options. With the recent launch of the Boeing's 787 jetliner as a backdrop to his remarks, Sanders will note the ongoing interest in novel titanium alloys, as they are compatible with composite materials because of their similar galvanic properties and coefficient of thermal expansion.

Matthieu Pachoutinsky, metallic material and processes engineer at Dassault Aviation of France, will provide an overview of titanium applications in Dassault airframes. He will focus on structures using forged cast parts, superplastic forming and diffusion bonding. "Whereas landing gear or engines manufacturers take the benefit of the wide range and high quality of material manufacturer's portfolio, Dassault chooses mainly the Ti-6-4 workhorse," Pachoutinsky stated in a preview of his remarks. "This allows us to rationalize our sources and to minimize qualification costs. Though our material portfolio is narrow, we can target a large range of structural parts, with appropriate optimized processes."

Dr. Michael Glavicic, senior materials engineer for international aerospace engine manufacturer Rolls Royce, will review a summary of the progress achieved in the company's "Advanced Titanium Microstructure Modeling" program, which is funded under the Metals Affordability Initiative (MAI). Glavicic states the goal of this program is to develop computational models that predict location specific microstructure and mechanical properties for wrought titanium alloys through the integration of phase field, crystal plasticity, variant selection, thermodynamic and neural net models into the commercially available finite-element software DEFORM®, supported by Scientific Forming Technologies Corp., Columbus, OH.

Dr. Daira Legzdina, principal product design engineer at Phoenix-based Honeywell Aerospace, will present "Additive Manufacturing of Titanium Alloys".  Additive manufacturing is a layer-by-layer technique of producing three-dimensional objects directly from a digital model without the need for hard tooling. Legzdina will spotlight three technologies are being considered for the production of titanium parts: Direct Laser Metal Sintering (DMLS); Electron Beam Melting (EBM); and Ion Fusion Formation (IFF). Legzdina's presentation will review the various technologies and discuss titanium alloy applications at Honeywell Aerospace.  Additive manufacturing, according to Legzdina, has the potential for major cost savings in the aerospace industry, offering the ability to produce prototypes quickly and inexpensively, ability to produce end of life parts where tooling is no longer available.

Eric J. Fodran, Ph.D., materials and process engineer, Northrop Grumman, Advanced Materials and Processes, Falls Church, VA will discuss Electron Beam (E-Beam) metallic Additive Manufacturing (AM) of Ti-6Al-4V alloy providing a unique opportunity to meet the demands of accelerating production needs by supplying a rapid, cost-effective means of fabricating metallic components that are otherwise cycle time intensive and costly to fabricate.

It's not too late to register for TITANIUM 2012 in Atlanta October 7-10th.
