Oxide dispersion strengthened (ODS) alloys are characterized by nanoscale oxide particles homogeneously dispersed in a metallic matrix. They have been developed driven by technological applications such as gas turbines that require increased material strength and creep properties at elevated temperatures, as well as increased resistance to high-energy neutron atmospheres as needed in modern nuclear reactors. Additive manufacturing (AM) offers the possibility to sustainably shorten the conventional sinter-based process chain of ODS materials and is additionally capable of the direct production of complex components. This work aims to critically review the current state of additive manufacturing of ODS alloys, which is mainly based on singular studies and the deduction of influence factors. Challenges in production are emphasized such as the production of suitable powder materials and consolidation techniques including in-situ manufacturing techniques. A main emphasis of this review are process-related influences on the final ODS material and its microstructural features as well as mechanical performance. Different classes of ODS alloys are presented and discussed along with their fields of use. Current drawbacks of ODS alloys are highlighted, enabling a focused development required for the widespread application of this class of materials.

氧化物弥散强化 (ODS) 合金的特征在于纳米级氧化物颗粒均匀分散在金属基体中。它们是在技术应用的推动下开发的，例如需要在高温下提高材料强度和蠕变性能的燃气轮机，以及现代核反应堆所需的提高对高能中子大气的抵抗力。增材制造 (AM) 提供了可持续缩短 ODS 材料传统烧结工艺链的可能性，并且还能够直接生产复杂部件。这项工作旨在批判性地回顾 ODS 合金增材制造的现状，这主要基于单一研究和影响因素的推导。强调了生产中的挑战，例如合适的粉末材料的生产和包括原位制造技术在内的固结技术。本次审查的主要重点是与工艺相关的对最终 ODS 材料及其微观结构特征以及机械性能的影响。介绍和讨论了不同类别的 ODS 合金及其使用领域。强调了 ODS 合金的当前缺点，从而实现了广泛应用此类材料所需的重点开发。介绍和讨论了不同类别的 ODS 合金及其使用领域。强调了 ODS 合金的当前缺点，从而实现了广泛应用此类材料所需的重点开发。介绍和讨论了不同类别的 ODS 合金及其使用领域。强调了 ODS 合金的当前缺点，从而实现了广泛应用此类材料所需的重点开发。
