Available in PDF, EPUB and Kindle. Book excerpt: In this study, the influence of ultrasonic nanocrystal surface modification (UNSM), which was applied as a post-additive manufacturing (AM), in terms of surface, tensile and tribological properties of Ti-6Al-4V alloy by selective laser melting (SLM) was investigated. Ti-6Al-4V alloy was subjected to UNSM at room and high temperatures (RT and HT). It was found that the UNSM enhanced the strength and reduced the roughness of the as-SLM sample, where both increased with increasing UNSM temperature. The UNSM bore influence on tribological properties, where the friction coefficient of the as-SLM sample reduced by about 25.8% and 305% and the wear resistance enhanced by about 41% and 246% at RT and HT, respectively. These are essentially attributed to the enhanced strength, smoothed surface and expelled pores from the surface. Based on SEM images, the damage caused by abrasive wear was the most observed in the wear track of the as-SLM sample than was caused by the highest wear rate. The UNSM temperature-dependent wear mechanisms were comprehensively investigated and elaborated based on the obtained experimental data and observed microstructural images. Indeed, a further investigation is required to improve the characteristics of as-SLM Ti-6Al-4V alloy to the wrought level due to the replacement possibility.

Download or read book Dissimilar Metal Welding written by Pierpaolo Carlone and published by MDPI. This book was released on 2019-12-12 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combination of distinct materials is a key issue in modern industry, whereas the driving concept is to design parts with the right material in the right place. In this framework, a great deal of attention is directed towards dissimilar welding and joining technologies. In the automotive sector, for instance, the concept of “tailored blanks”, introduced in the last decade, has further highlighted the necessity to weld dissimilar materials. As far as the aeronautic field is concerned, most structures are built combining very different materials and alloys, in order to match lightweight and structural performance requirements. In this framework, the application of fusion welding techniques, namely, tungsten inert gas or laser welding, is quite challenging due to the difference in physical properties, in particular the melting point, between adjoining materials. On the other hand, solid-state welding methods, such as the friction stir welding as well as linear friction welding processes, have already proved to be capable of manufacturing sound Al-Cu, Al-Ti, Al-SS, and Al-Mg joints, to cite but a few. Recently, promising results have also been obtained using hybrid methods. Considering the novelty of the topic, many relevant issues are still open, and many research groups are continuously publishing valuable results. The aim of this book is to finalize the latest contributions on this topic.

Download or read book Influence of Strain Rate Sensitivity SRS of Additive Manufactured Ti 6Al 4V on Nanoscale Wear Resistance written by Angelo Pelini and published by . This book was released on 2017 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread use of titanium alloys such as Ti-6Al-4V and the expense of manufacturing it, leads to a need of new manufacturing processes such as the innovative additive manufacturing technology of today. Ti-6Al-4V was studied in a series of experiments to determine the strain rate sensitivity of the material that was manufactured by conventional, mill-annealing, and additive manufacturing processes of electron beam melting and selective laser melting. Due to the high thermal cycles required in the hatching processes involved in building each layer of the part, and the rapid cooling, the grain size of dual phase titanium becomes very fine. Grain structure of each manufacturing process was studied and compared with the results. Constant rate of loading tests were performed on all three samples. Then the samples were tested in a multiple loading test where it was loaded at increasing maximum peak loads four times. The application of run-in wear can cause high friction where single asperity contact causes wear. Because of this, progressive scratch tests were performed at different loading rates and sliding speeds to compare to the indentation tests. Results show that grain size and structure influence the strain rate sensitivity as well as the scratch loading rate sensitivity. The results also show that the strain rate was affected by the fatigue induced by the multiple peak loads involved in the second test.

The strict relationship among process parameters, microstructure, and mechanical properties is a matter of interest in different areas, such as foundry, plastic forming, sintering, welding, etc., and regards both well-established and innovative processes. Nowadays, circular economy and sustainable technological development are dominant paradigms and impose an optimized use of resources, a lower energetic impact of industrial processes and new tasks for materials and products.

Download or read book Introduction to Unified Mechanics Theory with Applications written by Cemal Basaran and published by Springer Nature. This book was released on 2021-02-02 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text describes the mathematical formulation and proof of the unified mechanics theory (UMT) which is based on the unification of Newton’s laws and the laws of thermodynamics. It also presents formulations and experimental verifications of the theory for thermal, mechanical, electrical, corrosion, chemical and fatigue loads, and it discusses why the original universal laws of motion proposed by Isaac Newton in 1687 are incomplete. The author provides concrete examples, such as how Newton’s second law, F = ma, gives the initial acceleration of a soccer ball kicked by a player, but does not tell us how and when the ball would come to a stop. Over the course of Introduction to Unified Mechanics Theory, Dr. Basaran illustrates that Newtonian mechanics does not account for the thermodynamic changes happening in a system over its usable lifetime. And in this context, this book explains how to design a system to perform its intended functions safely over its usable life time and predicts the expected lifetime of the system without using empirical models, a process currently done using Newtonian mechanics and empirical degradation/failure/fatigue models which are curve-fit to test data. Written as a textbook suitable for upper-level undergraduate mechanics courses, as well as first year graduate level courses, this book is the result of over 25 years of scientific activity with the contribution of dozens of scientists from around the world including USA, Russia, Ukraine, Belarus, Spain, China, India and U.K.
