This book was released on 2007 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: A powder metallurgy route based on hot isostatic pressing (HIPing) of tape-cast monotapes was used for the direct fabrication of dense thin sheets of gamma titanium aluminide. Polarized light microscopy revealed a fine-grained microstructure but a few isolated larger grains were also present. The primarily metastable alpha2 microstructure of the rapidly solidified starting powder transformed to the equilibrium near-gamma microstructure during HIPing. Chemical analysis revealed that the dense sheet had a carbon content of 0.13 wt.%, which was only 0.04 wt.% higher than that of the starting powder, but the oxygen content was significantly higher, presumably introduced during the decanning step. The hardness measured using Vickers microindentation technique was 384 +/- 9 HV. Manipulation of the as-HIPed microstructure was performed by heating for up to 1 hour in flowing argon at temperatures below and above the alpha transus. Below 1250 deg C, limited grain growth and no discernable change in the as-HIPed (near-gamma) microstructure occurred.

Book Synopsis Gamma Titanium Aluminides 1999 by : Young-Won Kim
Download or read book Gamma Titanium Aluminides 1999 written by Young-Won Kim and published by Minerals, Metals, & Materials Society. This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 106 papers were selected from the presentations and have undergone stringent peer review. They consider nearly every aspect of current gamma-alloy technology, such as fundamental science, alloy development and design, process development, flow and fracture, creep behavior, microstructure and property evaluation, environmental behavior, and applications. The specific topics include powder metallurgy structures for use in various high-temperature aerospace applications, experiments and atomistic simulations of the deformation of polysynthetically twinned single crystals with near-hard orientations, the interplay of thermodynamics and transformation kinetics on microstructure development, solid solution strengthening mechanisms, studying localized strain at notches using displacement mapping and microstructural characterization, and the influence of gaseous species on the oxidation behavior at high temperature. The illustrations tend to be of high quality.

Book Synopsis Characterization of LENS TM Deposited Gamma Titanium Aluminides by : David Wanton Mahaffey
Download or read book Characterization of LENS TM Deposited Gamma Titanium Aluminides written by David Wanton Mahaffey and published by . This book was released on 2001 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Laser Engineered Net Shaping (LENSTM) process is a laser-based, direct metal manufacturing process that produces a near-net shape product. In the LENS process, metallic powder is delivered in a gas jet to a weld pool, which is produced by a 750W Continuous Wave Nd-YAG laser. Solidification takes place when the laser no longer heats the weld pool, and this process (when coupled to an X-Y mechanical stage) can be used to produce a large, dense, free-standing metal deposit. To date, the LENS process has been used to deposit primarily conventional alloy systems such as Ti 6-4 and stainless steels. In this study, we examine the micro structure and mechanical properties of LENS processed [gamma]-TiA1, an important emerging aerospace alloy. The LENS system was used to fabricate test coupons from Ti-46.5Al-2Cr-3Nb-0.2W-0.2C-0.15B (at%) powder, which were subsequently heat treated to produce a variety of micro structures. The as-deposited and heat treated coupons were characterized using Scanning Electron Microscopy and Transmission Electron Microscopy, in an attempt to correlate microstructural features to the measured mechanical properties. The LENS process was also used to fabricate near-net shape tensile bars, and the mechanical properties of the heat-treated material were measured in tension at room temperature. The mechanical property measurements show that this LENS-processed material has poor strength and limited ductility that is due to porosity that developed during fabrication.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes, interprets and comparatively discusses the results of research and development performed on the joining of gamma titanium aluminides during the past two decades. Although organized and presented by joining process, many of the observations made and relationships developed, particularly those regarding the weldability and welding metallurgy of gamma titanium aluminides, are broadly applicable. Generally, the basic welding processes and techniques utilized in the fusion and solid -state friction welding of conventional titanium alloys can also be applied to the welding of gamma titanium aluminides. However, the welding process parameters must be optimized, and in some instances the welding system significantly modified, to provide a comparatively slow weld cooling rate that minimize the potential for solid-state weld cracking, and that promotes the formation of a weld zone micro structure that exhibits suitable mechanical properties. Control of the weld cooling rate and the application of a postweld heat treatment can be used to generate a wide range of crack-free weld zone microstructures that correspondingly offer a range of mechanical property combinations. Gamma titanium aluminides can also be effectively joined using diffusion welding and conventional and diffusion brazing techniques.
