Selective laser melting (SLM) has established itself as the most prominent additive manufacturing (AM) process for metallic structures in aerospace, automotive and medical industries. For a reliable employment of this process, it has to conform to the demanding requirements of these industries in terms of quasistatic and, especially, fatigue performance. Shafaqat Siddique identifies the influence of SLM processing conditions on the microstructural features, and their corresponding influence on the mechanical behavior of the processed AlSi12 alloy structures. The author also gives insight into integrated manufacturing by combining conventional and SLM processes to get the synergic benefits. Requirements for fatigue-resistant designs in additive manufacturing are highlighted, and a novel method is developed for agile fatigue life prediction. About the Author Shafaqat Siddique worked as Scientific Assistant at TU Dortmund University, Department of Materials Test Engineering (WPT), headed by Prof. Dr.-Ing. Frank Walther, and completed his Ph.D. research in cooperation with Laser Zentrum Nord (LZN) in Hamburg. He continues his post-doctoral research at TU Dortmund University, Germany.

Fatigue failure of structures used in transportation, industry, medical equipment, and electronic components needs to build a link between cutting-edge experimental characterization and probabilistically grounded numerical and artificially intelligent tools. The physics involved in this process chain is computationally prohibitive to comprehend using traditional computation methods. Using machine learning and Bayesian statistics, a defect-correlated estimate of fatigue strength was developed. Fatigue, which is a random variable, is studied in a Bayesian-based machine learning algorithm. The stress-life model was used based on the compatibility condition of life and load distributions. The defect-correlated assessment of fatigue strength was established using the proposed machine learning and Bayesian statistics algorithms. It enabled the mapping of structural and process-induced fatigue characteristics into a geometry-independent load density chart across a wide range of fatigue regimes.

Philipp Wittke charakterisiert spanlos gefertigte Innengewinde aus den Aluminium- und Magnesiumlegierungen AlSi10Mg, AZ31 und AZ91. Neben der Entwicklung einer zerstörungsfreien Methode zur Beurteilung der Gewindequalität werden vom Autor grundlagenorientierte Untersuchungen durchgeführt, um den Einfluss von Prozessparametervariationen während der Gewindefertigung auf die Mikrostrukturen und somit auf die quasistatischen und zyklischen Eigenschaften der Innengewinde zu ermitteln. In diesem Zuge werden Strategien zur Abkürzung der Versuchszeiten für zyklische Untersuchungen entwickelt, bei denen mittels anwendungsoptimierter Sensorik charakteristische Kennwerte zur Lebensdauervorhersage ermittelt werden. Der Autor: Philipp Wittke arbeitete als wissenschaftlich Beschäftigter am Fachgebiet Werkstoffprüftechnik (WPT) der Technischen Universität Dortmund und schloss dort seine Promotion mit dem Fokus auf die zeiteffiziente Charakterisierung der Ermüdungseigenschaften neuartiger Gewindeverbindungen in Kooperation mit dem Institut für Spanende Fertigung (ISF) der Technischen Universität Dortmund ab.

Unter Betriebsbedingungen werden gelötete Bauteile statischen und zyklischen Beanspruchungen in aggressiven Abgaskondensaten ausgesetzt, sodass das Korrosionsermüdungsverhalten der Lötverbindungen für den zuverlässigen Betrieb entscheidend ist. Anke Schmiedt-Kalenborn charakterisiert mikrostrukturbasiert das Ermüdungs- und Korrosionsermüdungsverhalten von Lötverbindungen des metastabilen Austenits X2CrNi18‐9 (1.4307) mit Nickelbasislot Ni 620 und Goldbasislot Au 827. Dabei werden das Ermüdungsverhalten der Lötverbindungen an Luft, vor und nach einer langzeitigen Kondensatkorrosion nach VDA 230‐214, sowie in synthetischem Abgaskondensat K2.2 unter Verwendung einer neuartigen Prüfsystematik bewertet und zugrundeliegende verformungs- und korrosionsbedingte Schädigungsmechanismen separiert.

Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers, and scientists. AM has the ability to fabricate materials to produce parts with complex shapes without any theoretical restrictions combined with added functionalities. Selective laser melting (SLM), also known as laser-based powder bed processing (LPBF), is one of the main AM process that can be used to fabricate wide variety of materials that are Al-, Ti-, Fe-, Ni-, Co-, W-, Ag-, and Au-based, etc. However, several challenges need to be addressed systematically, such as development of new materials that suit the SLM process conditions so the process capabilities can be fully used to produce new properties in these materials. Other issues in the field are the lack of microstructure-property correlations, premature failure, etc. Accordingly, this Special Issue (book) focuses mainly on the microstructure-correlation in three different alloys: AlSi10Mg, Ti6Al4V, and 304L stainless steel, where six articles are presented. Hence, this Special Issue outlines microstructure-property correlations in the SLM processed materials and provides a value addition to the field of AM.

This work reviews the current state of the art in metallic microlattice structures, manufactured using the additive manufacturing processes of selective laser melting, electron beam melting, binder jetting and photopolymer wave guides. The emphasis is on structural performance (stiffness, strength and collapse). The field of additively manufactured metallic microlattice structures is fast changing and wide ranging, and is being driven by developments in manufacturing processes. This book takes a number of specific structural applications, viz. sandwich beams and panels, and energy absorbers, and a number of conventional metallic materials, and discusses the use of additive manufactured metallic microlattice structures to improve and enhance these structural performances. Structural performances considered includes such non linear effects as plasticity, material rupture, elastic and plastic instabilities, and impact loading. The specific discussions are put into the context of wider issues, such as the effects of realisation processes, the effects of structural scale, use of sophisticated analysis and synthesis methodologies, and the application of existing (conventional) structural theories. In this way, the specific discussions are put into the context of the emerging general fields of Architectured (Architected) Materials and Mechanical Metamaterials.
