In this review paper, studies involving process combinations between metal additive manufacturing (MAM) and post-MAM metal forming are reviewed to provide a summary of recent trends, applications, and challenges involved in hybrid (a combination of MAM and metal forming) manufacturing. Unlimited design flexibility, mass customization, reduction of expensive forming steps and material waste, production of dense metal parts at reduced manufacturing costs and time are the significant benefits offered by hybrid manufacturing (additive + conventional). Applicable thermomechanical processing (TMP), e.g. isothermal forging, hot rolling, hot extrusion, how and when they should be performed, and their impact on the evolution of structure and property of the additively manufactured parts is focused particularly. Extensive discussions on the microstructure and mechanical properties of additive manufactured preforms upon the application of TMP are carried out which impact the application ranges of these parts in the first place. Overall, this paper provides an attentive overview of the characterization of the material and process relationship combining material and manufacturing knowledge to optimize the right process for the right application that will serve as a benchmark for future research and development in manufacturing of metallic components with the combined effort of MAM and metal forming.

在这篇评论论文中，回顾了涉及金属增材制造 (MAM) 和后 MAM 金属成形之间工艺组合的研究，以总结混合（MAM 和金属成形的组合）制造中涉及的最新趋势、应用和挑战。无限的设计灵活性、大规模定制、减少昂贵的成型步骤和材料浪费、以降低的制造成本和时间生产高密度金属零件是混合制造（增材制造 + 传统制造）提供的显着优势。适用的热机械加工 (TMP)，例如等温锻造、热轧、热挤压、应如何以及何时执行，以及它们对增材制造零件的结构和性能演变的影响是特别关注的。对应用 TMP 的增材制造预制件的微观结构和机械性能进行了广泛的讨论，这首先影响了这些部件的应用范围。总体而言，本文对材料和工艺关系的表征进行了细致的概述，结合材料和制造知识，为正确的应用优化了正确的工艺，这将作为未来金属部件制造研究和开发的基准。 MAM 和金属成型的努力。
