Book Description
Tests were undertaken to evaluate the significance of performing equal-channel angular pressing using a die having an angle of 60 between the two channels. The tests were conducted using samples of pure aluminum arid an Al-1% Mg-O.2% Sc alloy. The results lead to the conclusion that the mechanical properties of samples in the as-pressed condition are similar for both 60 and 90 dies provided the data are compared at the same equivalent strains.

Book Description
Materials strengthened by conventional methods such as strain hardening, solute additions, precipitation and grain size refinement are often adopted in industrial processes. But there is limitation to the amount of deformation that these conventional methods can impact to a material. This study focused on the review of major mechanical properties of aluminum alloys in the presence of an ultrafine grain size into polycrystalline materials by subjecting the metal to an intense plastic straining through simple shear without any corresponding change in the cross-sectional dimensions of the sample. The effect of the heavy strain rate on the microstructure of aluminum alloys was in refinement of the coarse grains into ultrafine grain size by introducing a high density of dislocations and subsequently re-arranging the dislocations to form an array of grain boundaries. Hence, this investigation is aimed at gathering contributions on the influence of equal channel angular extrusion toward improving the mechanical properties of the aluminum alloys through intense plastic strain.

Book Description
ABSTRACT: Industry standard 6061 and 6063 Aluminum alloys were processed by equal channel angular extrusion (ECAE) at room temperature using a Bc route with a constant feed rate of 0.25 mm/s through a die angle of 90° between the die channels. The influence of ECAE processing on the evolution of the microstructure, microtexture and microhardness in the material was studied using orientation imaging microscopy (OIM), X-ray diffractometry, and Vickers microhardness testing. Detailed analysis was carried out on samples of the as-received, one, two, four and eight pass conditions.

Book Description
Thermo-Mechanical Processing of Metallic Materials describes the science and technology behind modern thermo-mechanical processing (TMP), including detailed descriptions of successful examples of its application in the industry. This graduate-level introductory resource aims to fill the gap between two scientific approaches and illustrate their successful linkage by the use of suitable modern case studies. The book is divided into three key sections focusing on the basics of metallic materials processing. The first section covers the microstructural science base of the subject, including the microstructure determined mechanical properties of metals. The second section deals with the current mechanical technology of plastic forming of metals. The concluding section demonstrates the interaction of the first two disciplines in a series of case studies of successful current TMP processing and looks ahead to possible new developments in the field. This text is designed for use by graduate students coming into the field, for a graduate course textbook, and for Materials and Mechanical Engineers working in this area in the industry. * Covers both physical metallurgy and metals processing* Links basic science to real everyday applications* Written by four internationally-known experts in the field

Book Description
Severe Plastic Deformation: Methods, Processing and Properties examines all severe plastic deformation techniques developed over the past two decades, exploring the appropriate severe plastic deformation method for a particular case. The book offers an overview of these methods, introduces ultrafine-grained and nano-grained metals and methods for various bulk, sheet, tubular and large size samples, reviews effective parameters to make a severe plastic deformation method better, from property (mechanical) and processing (cost, time, load, etc.) viewpoints, discusses mechanical, physical and chemical properties of UFG and NS metals, and concludes with various applications for these methods. Over the last several decades, a large number of severe plastic deformation methods have been developed for processing a wide array of metals for superior properties, making this a timely resource. Collects all severe plastic deformation methods in a unique reference Compares severe plastic deformation methods from several viewpoints, including processing and final property Classifies severe plastic deformation methods based on the sample shape and mechanics, as well as the properties achieved in the processed metal Introduces ultrafine-grained and nano-grained metals and methods for various bulk, sheet, tubular and large size samples

Book Description
A promising way to increase the strength of aluminum alloys is by grain refinement. Therefore the production of so-called ultra-fine grained (UFG) microstructures by severe plastic deformation (SPD) is a very interesting topic. One of the most common SPD processes is Equal Channel Angular Pressing (ECAP), which was compared to Confined Channel Die Pressing (CCDP) and cold rolling.In the focus of this work lays on the one hand the influence of different precipitation states on the formation of UFG structures and their influence on the mechanical properties and on the other hand it was examined if the thermal stability of these structures can be improved either by supersaturated solid solution(by impurity drag) or by precipitates (by grain boundary pinning).With a better understanding of the ongoing softening mechanisms a good combination of high strength and good ductility can be achievedby alternating SPD and heat treatment.

Book Description
Additive and Traditionally Manufactured Components: A Comparative Analysis of Mechanical Properties looks at the mechanical properties of materials produced by additive manufacturing (AM) and compares them with conventional methods. Since the production of objects by AM techniques can used in a broad array of materials, the alloys presented are the ones most commonly produced by AM - Al alloys, Ti alloys and steel. The book explores the six main types of techniques: Fused Deposition Method (FDM), Powder Bed Fusion (PBF), Inkjet Printing, Stereolithography (SLA), Direct Energy Deposition (DED) and Laminated Object Manufacturing (LOM), and follows with the techniques being utilized for fabrication. Testing of AM fabricated specimens, including tension, compression and hardness is included, along with a comparison of those results to specimens obtained by conventional fabrication methods. Topics covered include static deformation, time dependent deformation (creep), cyclic deformation (fatigue) and fracture in specimens. The book concludes with a review of the mechanical properties of nanoscale specimens obtained by AM. Thoroughly explores AM processes that can be utilized for experimental design Includes a review of dislocations observed in specimens obtained by AM Compares the impact of both additive and traditional manufacturing techniques on the mechanical properties of materials
