Available in PDF, EPUB and Kindle. Book excerpt: This project has as its focus microstructure control for improving fracture resistance of advanced aluminum alloys. Our progress report is divided into two major parts: Part I which is concerned with the quench sensitivity of the Al-Li-Cu-Mg alloy 2090 and the effect of quench rate on fracture behavior, and Part II which is concerned with the recovery and recrystallization mechanisms that occur in an alloy having a high density of dispersoid particles. The grain size of aluminum alloys can affect both strength and deformation behavior and often controls the degree of superplasticity during elevated temperature deformation. (jes).

Book Synopsis On the Influence of Dispersoids on the Particle Stimulated Nucleation of Recrystallization in an Al-Fe-Si Model Alloy by :
Download or read book On the Influence of Dispersoids on the Particle Stimulated Nucleation of Recrystallization in an Al-Fe-Si Model Alloy written by and published by . This book was released on 1997 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recrystallization of Al-alloys is controlled by precipitates. Whereas large particles generally promote recrystallization by particle stimulated nucleation, finely dispersed precipitates - either already present in the as-deformed state or precipitating during the recrystallization anneal - are known to strongly retard recrystallization. It was the aim of the present study to elucidate these concurring effects of large particles and small dispersoids on recrystallization in a ternary Al-Fe-Si model alloy. For that purpose, samples were prepared according to different pre-annealing treatments so as to comprise different states of precipitation and supersaturation. The evolution of microstructure and texture during rolling and recrystallization was characterized by metallography and by conventional X-ray texture analysis. EBSD-local texture investigations were employed to yield information on the efficiency of nucleation at the various nucleation sites and, consequently, on the influence of dispersoids on recrystallization.

Book Synopsis Metallurgy and Design of Alloys with Hierarchical Microstructures by : Krishnan K. Sankaran
Download or read book Metallurgy and Design of Alloys with Hierarchical Microstructures written by Krishnan K. Sankaran and published by Elsevier. This book was released on 2017-06-14 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metallurgy and Design of Alloys with Hierarchical Microstructures covers the fundamentals of processing-microstructure-property relationships and how multiple properties are balanced and optimized in materials with hierarchical microstructures widely used in critical applications. The discussion is based principally on metallic materials used in aircraft structures; however, because they have sufficiently diverse microstructures, the underlying principles can easily be extended to other materials systems. With the increasing microstructural complexity of structural materials, it is important for students, academic researchers and practicing engineers to possess the knowledge of how materials are optimized and how they will behave in service. The book integrates aspects of computational materials science, physical metallurgy, alloy design, process design, and structure-properties relationships, in a manner not done before. It fills a knowledge gap in the interrelationships of multiple microstructural and deformation mechanisms by applying the concepts and tools of designing microstructures for achieving combinations of engineering properties—such as strength, corrosion resistance, durability and damage tolerance in multi-component materials—used for critical structural applications. Discusses the science behind the properties and performance of advanced metallic materials Provides for the efficient design of materials and processes to satisfy targeted performance in materials and structures Enables the selection and development of new alloys for specific applications based upon evaluation of their microstructure as illustrated in this work

Download or read book On the Influence of Dispersoids on the Particle Stimulated Nucleation of Recrystallization written by and published by . This book was released on 1996 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recrystallization of Al alloys is controlled by precipitates. Whereas large particles are generally assumed to promote recrystallization by particle stimulated nucleation, finely dispersed precipitates, either already present in the as-deformed state or precipitating during the recrystallization anneal, are known to strongly retard the progress of recrystallization. It was the aim of this study to elucidate these concurring effects of large particles, and small dispersoids as well as of a supersaturation of solutes on recrystallization in a ternary Al-Fe-Si model alloy. Samples were prepared with different pre-annealing treatments to produce different states of precipitation and supersaturation. Evolution of the microstructure and of the crystallographic texture was followed during cold rolling and recrystallization. Conclusions were drawn on the efficiency of recrystallization nucleation at the various nucleation sites and, especially, on the influence of dispersoids on recrystallization.

Book Synopsis ANALYZING VARIATION IN DISPERSOID FORMATION IN ALUMINUM ALLOYS BY MINOR CHANGES IN HOMOGENIZATION TEMPERATURE by :
Download or read book ANALYZING VARIATION IN DISPERSOID FORMATION IN ALUMINUM ALLOYS BY MINOR CHANGES IN HOMOGENIZATION TEMPERATURE written by and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The homogenization of billets in the aluminum extrusion industry is a critical step that removes chemical segregation from casting, dissolves low melting point phases, forms nanoscale dispersoid phases, and promotes the beta to alpha transformation of iron particles in the matrix. With ever increasing use of aluminum extrusion in the automotive industry there is a constant need for increased efficiency and consistency in processing of extruded aluminum. The work in this thesis explores the effects of 10℗ʻC differences in the homogenization temperature on the formation of dispersoids in 6082 alloys used in the automotive industry. The role of dispersoids is to prevent the recrystallization of grains during extrusion giving a more uniform grain structure, improved mechanical properties, and improved corrosion resistance when compared to dispersoid-free alloys. This work found a 10°C increase in homogenization temperature resulted in a 5-15% decrease in dispersoid density, 5-10% increase in dispersoid size, and noticeable effect on mechanical and chemical properties. This effect was maintained regardless of the holding time, temperature, or ramp rate used for homogenization. Additional studies on the effects of two-step homogenizations found similar results on the variation in dispersoid density but had improved properties when compared to one-step homogenization cycles currently used in industry, shedding light on the importance of dispersoid nucleation mechanism in developing improved thermal processing of billets.
