Download or read book Severe Plastic Deformation Techniques written by Marcello Cabibbo and published by BoD – Books on Demand. This book was released on 2017-08-09 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain size is recognized as a key microstructural factor affecting mechanical and, to some extent, physical properties of metals and metallic materials. For this reason, all the means designed to control and modify the grain size are considered a proper way to design and tailor metallic materials with desired properties. In this sense, microstructure refinement through severe plastic deformation (SPD) techniques can be considered a key method for this purpose. A typical SPD process is currently defined as any method of metal forming under extensive hydrostatic pressure intended to impose a very high strain on a bulk solid without involving any significant change in the overall dimensions and having the ability to produce exceptional grain refinement. What makes SPD processing techniques so popular and attractive is the possibility of using them to enhance the strength behavior of conventional metallic materials by a factor of up to eight for pure metals such as copper and by some 30-50% for alloys. Despite the impressive property improvement achievable with SPD techniques, their uptake by industry has been rather sluggish. This book intends to give a panorama of the typical SPD techniques intended to optimize the mechanical and physical properties of metals through a significant grain size reduction process. Modeling for this purpose is also presented.

Download or read book Investigation of the Mechanical Behavior of WE43 Magnesium Alloy Modified Via Multi Directional Forging written by Camila Rita De Souza and published by . This book was released on 2017 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mechanical processing improves the mechanical behavior of modern materials, thus increasing their strength, toughness, and other physical properties. This research focuses on the mechanical properties of magnesium alloy WE43 under conditions of severe plastic deformation. The main objective of this research is to characterize structurally the magnesium alloy and analyze the formation of bulk ultrafine grains produced by two main techniques which promote the change in grain size and consequently the increase of the mechanical strength. Multi Directional Forging is a compression procedure applied to the material in all three directions, maintaining the dimensional ratio and increasing the strain produced until the cumulative strain be greater than 2.0. This was conducted at 550 °C. As magnesium alloy WE43 has good properties at higher temperatures; the cumulative plastic strain obtained was higher than 2.0. To complement the study of the strength increase via plastic deformation, Equal Channel Angular Processing was applied at three different temperatures. The required stress to push the material through the die at 550 °C was 867 MPa. The results show a moderate decrease in grain size from 18 μm to 14 [mu]m in ECAP and 12 [mu]m in Multi Directional Forging. This decrease in grain size results in an increase in the hardness. In view of the brittleness of the magnesium alloy it was not possible to increase the plastic strain as expected in Multi Directional Forging per pass; the samples fractured if the stress was increased beyond 230 MPa. The yield stress at 1.6 x 10-2 s-1 increased from 87 MPa for the initial condition, to 115 MPa for the specimens subjected to a strained. In dynamic compression test, experiments were conducted at a strain rate of 2.5x103 s-1 and the yield stress increased to 246 MPa. This shows that magnesium has a high strain-rate sensitivity.
