Available in PDF, EPUB and Kindle. Book excerpt: By thermally cycling through their transformation temperature range, coarse-grained, polymorphic materials can be deformed superplastically, owing to the emergence of transformation mismatch plasticity (or transformation superplasticity) as a deformation mechanism. This mechanism is investigated under biaxial stress conditions during thermal cycling of unalloyed titanium, Ti-6Al-4V, and their composites (Ti/10 vol.% TiC{sub p}, Ti-6Al-4V/10 vol% TiC{sub p} and Ti-6Al-4V/5 vol.% TiB{sub w}). During gas-pressure dome bulging experiments, the dome height was measured as a function of forming time. Adapting existing models of biaxial doming to the case of transformation superplasticity where the strain-rate sensitivity is unity, we verify the operation of this deformation mechanism in all experimental materials, and compare the biaxial results to uniaxial thermal cycling results on the same materials. Finally, existing thickness distribution models are compared with experimentally measured profiles.

Available in PDF, EPUB and Kindle. Book excerpt: This program was directed at the establishment of superplastic forming of Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo alloys as a production process. Forming studies were pursued to evaluate the process parameters of superplastic forming and to extend the process to forming aircraft structural components. A detailed study was carried out on the effect of forming parameter variations with the two titanium alloys and two configurations. It was found that the degree of forming was directly related to time at elevated temperatures. Optimum sealing techniques to eliminate atmospheric contamination of the titanium sheet material were established. Twenty-three parts were formed in six different configurations to assess the forming parameters needed to fabricate components of varying shapes and dimensions. The process was then extended to superplastic forming of Ti-6Al-4V and Ti-6Al-2Sn-4Zr-2Mo sheet metal alloys through the fabrication of full-scale complex structural configurations. A total of 20 full-scale formed parts was produced utilizing gas pressure forming at elevated temperatures. Structural testing was accomplished on each configuration and alloy showing the compatibility of superplastic formed parts with aircraft structural integrity requirements. Substantial cost savings were shown to be possible.

Download or read book Mechanisms and Mechanics of Transformation mismatch Plasticity in Titanium Alloys and Composites written by Christopher Schuh and published by . This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Transformation-mismatch plasticity is a deformation mechanism that occurs in polymorphic materials when a small external stress is imposed during their phase transformation. Internal mismatch, due to the density difference between polymorphs, is accommodated plastically in the weaker phase, and the accommodation strains are biased to occur in the direction of the external stress. This leads to average Newtonian flow, which can be accumulated after multiple transformations to achieve superplastic strains (i.e., transformation superplasticity).
Download or read book Superplastic Forming Diffusion Bonding Technology of Titanium Alloys written by Zhiqiang Li and published by Springer Nature. This book was released on 2023-10-26 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive illustration to the superplastic forming/diffusion bonding (SPF/DB) technology developed over decades of research on titanium alloys, process modeling, and its application. SPF/DB technology plays key roles in building aviation components with complicated structures, with highly beneficial effects when well designed. With the ever-increasing demand on components with multiple layers, there is an urgent need for an updated assessment of traditional and modern SPF/DB processing methods. Success critically depends on making the most practical and effective choice of SPF/DB method for a given application. The book introduces titanium and titanium alloys, SPF/DB processing and its modeling, and applications for building typical single or multiple layer(s) structures. Particular attention is paid to illustrating the microstructure evolution during SPF/DB processes. The information for making technical decisions about optimal choice of measurement and evaluation methods is also given in the book. Each chapter follows a focused and pragmatic format. Fully illustrated throughout, the book presents the state of the art in SPF/DB technology in a manner that makes it useful for engineers to improve the established forming processes and quality of components. This book is an essential reading material for industrial practitioners, academic researchers and postgraduates.

This book was released on 2013-03-15 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid Solidification Processing of molten metals and alloys has proved to be a reliable route for producing new and advanced materials. The Chill-Block Melt Spin (CBMS) technique is important because its simplicity, flexibility and perfection. High quality materials can be produced with lower costs, as compared to other routes, by refining the microstructure and trapping the nucleated (new) metastable phases. Melt-spun ribbons subsequently produced can then be consolidated to produce billets and sheets that can be used in many industries especially high-tech industries such as aerospace and racing automobiles. This book contains several perspectives about CBMS technology and should be a useful review for undergraduate and post-graduate metallurgy students.
