Aqueous corrosion of additively manufactured multi principal element alloys: a critical review
This review explores the aqueous corrosion of multi-principal element alloys (MPEAs) that have been prepared using additive manufacturing (AM), inclusive of laser powder bed fusion, directed energy deposition and electron beam melting. The impact of additive manufacturing techniques upon the microstructural features of MPEAs may influence corrosion resistance, through inducing an influence on grain size, phase distribution, and local nano-chemistry. Emphasis is placed on the comparative performance of MPEAs in various corrosive environments, highlighting key findings. The review aims to provide insights into the influence of AM as a processing method for MPEA production – in the context of impact upon corrosion.
