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.

激光增材制造中的原位多金属合金化：简要综述

增材制造（AM）越来越多地用于原位合金化，促进了多金属部件的生产，通常称为多金属AM （MMAM）。这种方法能够设计出复杂的、功能性的、高度定制的、具有优越机械性能的产品。尽管MMAM原位合金化的进展落后于单金属AM，但在这一新兴领域取得了显着进展。本文简要回顾了过去十年中激光增材制造合金的原位合金化，特别关注钛（Ti）基MMAM和其他金属系统。它系统地综合了当前的见解，解决了预处理准备（例如，粉末原料的制备和改性），过程中的调整（例如，合金化学和参数优化的改变）和数值模拟。这些因素共同对MMAM产品的显微组织特征和力学性能产生深远的影响。

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.
