Download or read book Microstructure And Properties Of Materials Vol 2 written by James C M Li and published by World Scientific Publishing Company. This book was released on 2000-10-09 with total page 454 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second volume of an advanced textbook on microstructure and properties of materials. (The first volume is on aluminum alloys, nickel-based superalloys, metal matrix composites, polymer matrix composites, ceramics matrix composites, inorganic glasses, superconducting materials and magnetic materials). It covers titanium alloys, titanium aluminides, iron aluminides, iron and steels, iron-based bulk amorphous alloys and nanocrystalline materials.There are many elementary materials science textbooks, but one can find very few advanced texts suitable for graduate school courses. The contributors to this volume are experts in the subject, and hence, together with the first volume, it is a good text for graduate microstructure courses. It is a rich source of design ideas and applications, and will provide a good understanding of how microstructure affects the properties of materials.Chapter 1, on titanium alloys, covers production, thermomechanical processing, microstructure, mechanical properties and applications. Chapter 2, on titanium aluminides, discusses phase stability, bulk and defect properties, deformation mechanisms of single phase materials and polysynthetically twinned crystals, and interfacial structures and energies between phases of different compositions. Chapter 3, on iron aluminides, reviews the physical and mechanical metallurgy of Fe3Al and FeAl, the two important structural intermetallics. Chapter 4, on iron and steels, presents methodology, microstructure at various levels, strength, ductility and strengthening, toughness and toughening, environmental cracking and design against fracture for many different kinds of steels. Chapter 5, on bulk amorphous alloys, covers the critical cooling rate and the effect of composition on glass formation and the accompanying mechanical and magnetic properties of the glasses. Chapter 6, on nanocrystalline materials, describes the preparation from vapor, liquid and solid states, microstructure including grain boundaries and their junctions, stability with respect to grain growth, particulate consolidation while maintaining the nanoscale microstructure, physical, chemical, mechanical, electric, magnetic and optical properties and applications in cutting tools, superplasticity, coatings, transformers, magnetic recordings, catalysis and hydrogen storage.

Download or read book The Effects of Annealing Treatment on Mechanical Behavior and Microstructure in Nanocrystalline Nickel written by Hsiao-Wei Yang and published by . This book was released on 2009 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocrystalline (nc) materials are characterized by a grain size in the range 1-200 nm. Because of this characteristic, these materials exhibit unique microstructures in which the volume of grain boundaries is significant. Nc-materials offer interesting possibilities related to many structural applications. In order to explore some of these possibilities, an understanding of the origin of mechanical properties such as strength, hardness, and ductility is essential. Mechanical properties in materials are very sensitive to their microstructure. One important process that can be used to manipulate the details microstructure in materials is annealing. In the present dissertation, annealing treatment was utilized to provide insight into the correlation between mechanical properties and microstructure. Primary among the mechanical properties that were selected for investigation are hardness, the elastic modulus, strength and ductility. Experiments on hardness and the modulus of elasticity were conducted at room temperature on samples of electrodeposited (ED) nc-Ni that were annealed at temperatures ranging from 323 K to 693 K. The results showed the presence of three regions: regions I, II, and III. In region I (300 K T 350 K), hardness and the elastic modulus remained essentially constant. In region II (350

Download or read book Synthesis Characterization and Mechanical Properties of Nanocrystalline NiAl written by and published by . This book was released on 1996 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanocrystalline NiAl was produced from pre-cast alloys using an electron beam inert gas condensation system. In-situ compaction was carried out at 100-300 C under vacuum conditions. Energy dispersive spectroscopy was used to determine chemical composition and homogeneity. Average grain sizes in the range 4-10 nm were found from TEM dark field analyses. A compression-cage fixture was designed to perform disk bend tests. These tests revealed substantial room temperature ductility in nanocrystalline NiAl, while coarse grained NiAl showed no measurable room temperature ductility.

Download or read book Mechanical Properties in Progressive Mechanically Processed Metallic Materials written by Radim Kocich and published by MDPI. This book was released on 2021-02-24 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The demands on innovative materials given by the ever-increasing requirements of contemporary industry require the use of high-performance engineering materials. The properties of materials and alloys are a result of their structures, which can primarily be affected by the preparation/production process. However, the production of materials featuring high levels of the required properties without the necessity to use costly alloying elements or time- and money-demanding heat treatment technologies typically used to enhance the mechanical properties of metallic materials (especially specific strength) still remains a challenge. The introduction of thermomechanical treatment represented a breakthrough in grain refinement, consequently leading to significant improvement of the mechanical properties of metallic materials. Contrary to conventional production technologies, the main advantage of such treatment is the possibility to precisely control structural phenomena that affect the final mechanical and utility properties. Thermomechanical treatment can only decrease the grain size to the scale of microns. However, further research devoted to pushing materials’ performance beyond the limits led to the introduction of severe plastic deformation (SPD) methods providing producers with the ability to acquire ultra-fine-grained and nanoscaled metallic materials with superior mechanical properties. SPD methods can be performed with the help of conventional forming equipment; however, many newly designed processes have also been introduced.
