Abstract

During structural alloy development, the initial microstructure design is mainly considered in the context of achieving a balance of mechanical properties, with corrosion resistance often considered much later in the process. This perspective uses illustrations from degradation mechanisms in 3D-printed alloys and in-service microstructure evolution-driven mechanisms to show the importance of microstructure design for corrosion resistance and mechanical properties simultaneously, to improve the reliability of critical infrastructure.

结构合金设计中的抗腐蚀微结构工程

在结构合金开发过程中，最初的微观结构设计主要是在实现机械性能平衡的背景下考虑的，而耐腐蚀性往往是在开发过程的后期才考虑的。本视角从三维打印合金的降解机制和在役微结构演化驱动机制两方面进行说明，以显示微结构设计同时兼顾耐腐蚀性和机械性能的重要性，从而提高关键基础设施的可靠性。

期刊介绍： npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
