Download or read book Stability and Optimization of P Phase Precipitates in Nickel titanium palladium Shape Memory Alloys written by Anne Catherine Coppa and published by . This book was released on 2015 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The motivation for this research is the understanding of phase transformations that lead to an increase in the shape memory effect (SME) transformation temperature in a Ni-Ti-Pd shape memory alloy (SMA). The research addressed three major parts of this transformation - (1) The phase stability of the P-phase precipitate previously discovered with an emphasis on its stoichiometric limits by changing the Ni and Pd content with the Ti11(Ni, Pd)13 ratio; (2) The effects of P-phase precipitation on the martensitic transformation temperature in near-equiatomic Ti(Ni, Pd) alloys; and (3) The effects of dilute additions of Hf (0.1-1 at.%) to the precipitation and shape memory transformation temperature in Ni-Ti-Pd. P-phase stabilization: The compositional limits of the P-phase have been systematically studied by varying the Pd and Ni content in the P-phase's Ti11(Ni+Pd)13 stoichiometry. Each alloy was solutionized at 1050oC followed by water quenching, and aging at 400oC for 100 hours. Four distinct phases were identified - Ti2Pd3, B2 Ni-Ti, P- and P1-phases dependent on alloy composition - by electron and x-ray diffraction. The latter precipitate phases become more stable with increasing Ni at the expense of Pd content. Atom probe tomography revealed the P-phase composition to be 45.8Ti-29.2Ni-25Pd (at.%) or Ti11(Ni7Pd6) as compared to the P1-phase 44.7Ti- 45.8Ni-9.4Pd (at.%) or Ti5Ni5Pd. Optimization of P-phase precipitation: The effect of aging time and temperature on precipitation and subsequent martensitic transformation temperatures for a series of Ni-(50.5-49.2)Ti-32Pd (at.%) shape memory alloys has been studied. Structure-property relationships were developed through detailed microstructural characterization involving transmission electron microscopy, diffraction analysis, and atom probe tomography with links to microhardness measurements and transformation temperatures established by differential scanning calorimetry. The Ti-rich alloy contained relatively coarse Ti2Ni in a B19 matrix and had the highest martensitic transformation temperatures (Ms ~ 280°C) independent of aging condition. After aging, the two Ti-lean alloys contained P-phase precipitates in a B19 matrix. The increase in transformation temperature was associated with a near 50 at.% Ti composition in the matrix phase. Quaternary alloys addition to P-phase: The effect of Hf (0 - 1 at. %) additions in a Ni-Ti-Pd alloy on P-phase precipitation and martensitic transformations were studied. The addition of hafnium promoted an increase in strain within the matrix which resulted in the refinement of precipitates upon precipitation with a corresponding increase in number density. The overlapping strain fields of the precipitates created from the decrease in inter-precipitate spacing reduced the matrix volume to be less than the critical free volume size required for the martensitic transformation over the temperature range studied (183 K to 573 K), hence a deleterious suppression of the transformation temperature. Hafnium was also noted to delay the aging time to achieve peak hardness, suggesting a reduction in growth and coarsening kinetics.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a working knowledge of the modeling and engineering applications of shape memory alloys (SMAs), beginning with a rigorous introduction to continuum mechanics and continuum thermodynamics as they relate to the development of SMA modeling.Modern SMAs can recover from large amounts of bending and deformation, and millions of repetitions within recoverable ranges. SMAs are used in the medical industry to create stents, in the dental industry to create dental and orthodontic archwires, and in the aerospace industry to create fluid fittings. The text presents a unified approach to the constitutive modeling of SMAs, including modeling of magnetic and high temperature SMAs.
Download or read book Design of Shape Memory Alloy SMA Actuators written by Ashwin Rao and published by Springer. This book was released on 2015-05-08 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: This short monograph presents an analysis and design methodology for shape memory alloy (SMA) components such as wires, beams, and springs for different applications. The solid-solid, diffusionless phase transformations in thermally responsive SMA allows them to demonstrate unique characteristics like superelasticity and shape memory effects. The combined sensing and actuating capabilities of such materials allows them to provide a system level response by combining multiple functions in a single material system. In SMA, the combined mechanical and thermal loading effects influence the functionality of such materials. The aim of this book is to make the analysis of these materials accessible to designers by developing a "strength of materials" approach to the analysis and design of such SMA components inspired from their various applications with a review of various factors influencing the design process for such materials.
Download or read book Engineering Aspects of Shape Memory Alloys written by T W Duerig and published by Butterworth-Heinemann. This book was released on 2013-10-22 with total page 512 pages. Available in PDF, EPUB and Kindle. Book excerpt: Engineering Aspects of Shape Memory Alloys provides an understanding of shape memory by defining terms, properties, and applications. It includes tutorials, overviews, and specific design examples—all written with the intention of minimizing the science and maximizing the engineering aspects. Although the individual chapters have been written by many different authors, each one of the best in their fields, the overall tone and intent of the book is not that of a proceedings, but that of a textbook. The book consists of five parts. Part I deals with the mechanism of shape memory and the alloys that exhibit the effect. It also defines many essential terms that will be used in later parts. Part II deals primarily with constrained recovery, but to some extent with free recovery. There is an introductory paper which defines terms and principles, then several specific examples of products based on constrained recovery. Both Parts III and IV deal with actuators. Part III introduces engineering principles while Part IV presents several of the specific examples. Finally, Part V deals with superelasticity, with an introductory paper and then several specific examples of product engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic approach to realizing NiTi shape memory alloy actuation, and is aimed at science and engineering students who would like to develop a better understanding of the behaviors of SMAs, and learn to design, simulate, control, and fabricate these actuators in a systematic approach. Several innovative biomedical applications of SMAs are discussed. These include orthopedic, rehabilitation, assistive, cardiovascular, and surgery devices and tools. To this end unique actuation mechanisms are discussed. These include antagonistic bi-stable shape memory-superelastic actuation, shape memory spring actuation, and multi axial tension-torsion actuation. These actuation mechanisms open new possibilities for creating adaptive structures and biomedical devices by using SMAs.
