Abstract

In this work the SS316L + SiC Metal Matrix Composites (MMCs) was characterized. Different amount of Silicon Carbide (SiC) was added as reinforcements in a matrix of 316L Stainless Steel (SS316L): 10% in volume and 20% in volume. The composites were produced by Laser Cladding (LC). &#13;An evolution of the characteristics of the cladded deposit was observed with the change of LC process parameters, such as power, scanning speed and powders utilized. For the production of SS316L + 20% SiC deposit the powders were used in original (as-produced) and milled conditions. While for the SS316L + 10% deposit only original powders were utilized. &#13;The deposits with 10% in volume of original SiC powders and with 20% in volume of milled SiC powders exhibit a compact structure with absence of porosity and/or cracks, and good interaction with the substrate.&#13;The characterization was made by means of Optical Microscope (OM), Scanning Electron Microscope (SEM), Differential Thermal Analysis (DTA), Thermo Gravimetry Analysis (TGA), Macro-hardness tests and chemical analysis. &#13;The powders of the two different compositions and after the milling process were characterized, especially by different thermal analysis and microscope observations. Considering their characteristic, the best condition for the Additive Manufacturing (AM) process was chosen and the samples were fabricated by LC. The microstructural characterization on the deposits revealed the formation of carbides that reinforce the matrix. The morphology and the composition of phases of the different deposits were compared by using microscope observations and thermal analyses.

Abstract

Airworthiness, as a field, encompasses the technical and non-technical activities required to design, certify, produce, maintain, and safely operate an aircraft throughout its lifespan. The evolving technology, science, and engineering methods and, most importantly, aviation regulation, offer new opportunities and create, new challenges for the aviation industry. This book assembles review and research articles across a variety of topics in the field of airworthiness: aircraft maintenance, safety management, human factors, cost analysis, structures, risk assessment, unmanned aerial vehicles and regulations. This selection of papers informs the industry practitioners and researchers on important issues.

Abstract

Additive Manufacturing (AM), more popularly known as 3D printing, is transforming the industry. AM of metal components with virtually no geometric limitations has enabled new product design options and opportunities, increased product performance, shorter cycle time in part production, total cost reduction, shortened lead time, improved material efficiency, more sustainable products and processes, full circularity in the economy, and new revenue streams. This Special Issue of Metals gives an up-to-date account of the state of the art in AM.

Abstract

This book aims to summarize the latest achievements in the development and manufacturing of modern biomaterials used in modern medicine and dentistry, for example, in cases where, as a result of a traffic or sports accident, aging, resection of organs after oncological surgery, or dangerous inflammation, there is a need to replace lost organs, tissues, and parts of the human body. The essence of biomedical materials is their constant contact with living tissues, organisms, or microorganisms and, therefore, they should meet numerous requirements from various fields, including medicine, biology, chemistry, tissue engineering, and materials science. For this reason, biomaterials must be compatible with the organism, and biocompatibility issues must be addressed before using the product in a clinical setting. The production and synthesis of biomaterials require the use of various technologies and methods to obtain the appropriate material, which is then processed using advanced material processing technologies. Often, however, it is necessary to directly manufacture a specific product with individualized geometric features and properties tailored to the requirements of a particular patient. In such cases, additive manufacturing methods are increasingly used. In this sense, it can be considered that the Biomaterials 4.0 stage has been reached, and detailed information is included in the individual chapters of this book on the achievements in the development and manufacturing of modern biomaterials used in modern regenerative medicine, regenerative dentistry, and tissue engineering.
