Abstract
Additive manufacturing (AM) has increasingly been employed for in situ alloying, facilitating the production of multi-metallic components, often referred to as multi-metal AM (MMAM). This approach enables the design of intricate, functional, and highly customized products with superior mechanical performance. Although the advancements in MMAM in-situ alloying have lagged behind those in single-metal AM, notable progress has been achieved in this emerging field. This concise review examines in situ alloying in laser-based AM alloys over the past decade, with a particular focus on titanium (Ti)-based MMAM and other metal systems. It systematically synthesizes current insights, addressing pre-processing preparations (e.g., powder feedstock preparation and modification), in-process adjustments (e.g., alternations in alloy chemistry and parameters optimization), and numerical simulations. These elements collectively exert a profound influence on the microstructural characteristics and mechanical performance of MMAM products.
期刊介绍:
Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development.
The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
