Download or read book Austenitic TRIP TWIP Steels and Steel Zirconia Composites written by Horst Biermann and published by Springer Nature. This book was released on 2020-05-29 with total page 841 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents a collection of the most up-to-date research results in the field of steel development with a focus on pioneering alloy concepts that result in previously unattainable materials properties. Specifically, it gives a detailed overview of the marriage of high-performance steels of the highest strength and form-ability with damage-tolerant zirconia ceramics by innovative manufacturing technologies, thereby yielding a new class of high-performance composite materials. This book describes how new high-alloy stainless TRIP/TWIP steels (TRIP: TRansformation-Induced Plasticity, TWIP: TWinning-induced Plasticity) are combined with zirconium dioxide ceramics in powder metallurgical routes and via melt infiltration to form novel TRIP-matrix composites. This work also provides a timely perspective on new compact and damage-tolerant composite materials, filigree light-weight structures as well as gradient materials, and a close understanding of the mechanisms of the phase transformations. With a detailed application analysis of state-of-the-art methods in spatial and temporal high-resolution structural analysis, in combination with advanced simulation and modelling, this edited volume is ideal for researchers and engineers working in modern steel development, as well as for graduate students of metallurgy and materials science and engineering.

Download or read book On the Impact of Non Optimal Parameters in Additive Manufacturing written by Julia Richter and published by BoD – Books on Demand. This book was released on 2024-01-01 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Die additive Fertigung mit ihrem schichtweisen Aufbau bietet eine Vielzahl attraktiver Eigenschaften wie eine noch nie dagewesene Gestaltungsfreiheit und maßgeschneiderte mechanische Eigenschaften. Unter anderem erlaubt das pulverbettbasierte Laserstrahlschmelzen von Metallen (PBF-LB/M) die Herstellung hochkomplexer Teile mit einem Minimum an Nachbearbeitungsaufwand. Da die additiven Fertigungsverfahren jedoch vergleichsweise neu sind, gibt es noch einige offene Fragen bezüglich der Prozess-Mikrostruktur-Eigenschafts-Beziehung zu klären. In der vorliegenden Arbeit wurde der Einfluss verschiedener Prozessabweichungen, die einen nicht-idealen Prozesszustand darstellen, auf die Mikrostruktur und die mechanischen Eigenschaften von Eisen- und Aluminiumbasislegierungen untersucht. Aufgrund der großen Anzahl unterschiedlicher Prozessabweichungen konzentrierte sich diese Arbeit auf drei exemplarische, nicht-ideale Prozesse, d.h. Prozessunterbrechungen, die Verwendung von nicht-sphärischen Pulvern und einen variierenden Prozessgasstrom. Durch den Einsatz hochauflösender elektronenmikroskopischer Analysemethoden sowie der Röntgentomographie konnten tiefe Einblicke in die Mikrostruktur und die Defektbildungsmechanismen gewonnen werden. Der Einfluss von Mikrostruktur und Defekten auf die Schädigungsentwicklung unter mechanischer Belastung wurde analysiert und eine Modellidee für eine robuste Produktion abgeleitet und mit bestehenden Konzepten diskutiert.

Download or read book Rolling of Advanced High Strength Steels written by Jingwei Zhao and published by CRC Press. This book was released on 2017-07-12 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: Advanced high strength steels (AHSSs) for auto-making are primarily produced by rolling, plus heat treatment technologies if necessary. However, due to the metallurgical complexity of AHSSs, it is impossible to roll all of the AHSS grades in a rolling mill with the same rolling technology. Each of AHSSs has unique applications in vehicles, and specified rolling technologies are required to produce high quality AHSS products where they might be the best employed to meet performance demands of the automotive parts. Such background has prompted the publication of this scholarly book in the area of rolling of AHSSs with a purpose of providing readers with a valuable technical document that can be used in the research and development of AHSSs for automotive and other manufacturing industries. With contributors from USA, Germany, Poland, Italy, Spain, Austria, Australia, China, India and Iran, the book highlights the latest advances in rolling technologies of AHSSs. It focuses on the theory, simulation and practice of the rolling of AHSSs: The book introduces the history, types and advances of AHSSs and their processes; proposes new theory that is applicable to the rolling of AHSSs, presents mathematical and numerical modelling of AHSSs in rolling; covers thermomechanical processing technologies of AHSSs; provides case studies on the rolling practice of the most popular AHSSs and includes other rolling-related technologies of AHSSs. The book will be useful for both theoretical and applied research aimed at AHSSs rolling technologies, and will be a scientific and valuable literature for the metallurgists, engineers, materials scientists, academics and graduate students who are studying and working with AHSSs and their rolling technologies worldwide.
