CSP - Beyond Nickel-Based Superalloys II Conference
Abstract
Beyond Nickel-Based Superalloys II Conference.The conference will address the multi-disciplinary nature of high temperature alloy research and development and will attempt to bring together those who have expertise in specific aspects of these alloys. Depending on the system, its manufacturing route and application, a variety of questions have to be answered through experimental investigations as well as by simulation and modeling. Presentations will cover:~ alloy development for creep behavior and oxidation resistance~ mechanical behavior including ductility from RT up to application temperature, fatigue behavior and resistance to crack propagation~ microstructure observations (dislocation structures, phase changes) and correlation to mechanical behavior~ experimental approaches including "exotic" experimental setups (alloy development on a small scale, in-situ testing and characterization)Nickel-based superalloys aree widely used in elevated temperature structural applications that demand high strength, damage tolerance and environmental resistance.A key application of these materials is in the turbine engines used in surface ships, Naval aviation and electrical power generation. The demand for increased performance, reliability and efficiency from such engines necessitates future engine designs that willsubject key engine components to even higher temperatures and stresses than are currently experienced. New alloy systems with potential to supersede nickel-based superalloys are beingextensively studied by many research groups worldwide. This meeting provides a single venue to review technical progress of this international research community and provide guidance to the NRE, particularly ONR 30, 33 and 35, of the development in the area of structural material and mechanics systems and its use for designing and implementing advanced platforms with superior performance over current systems using materials that are much stronger, and with greater endurance in harsh environment than those currently available. This has been coordinated with Dave Shifler in ONR332. This conference supports an integral part of his research program and will provide valuable insights and emerging science that can be leveraged in his development of high temperature/harsh environmental tolerant materials for next generation Naval turbine engines.
