Abstract
The influence of disordered and ordered body-centered cubic (BCC-β and B2-β′) secondary phases on the mechanical properties and cavitation erosion-corrosion (CE-C) behavior of BCC/B2 strengthened FeNiCrMoAl-based multi-principal element alloy (MPEA) was systematically investigated. An increased β/β′ phases content enhanced the MPEAs’ strengths while maintaining good ductility. However, this increases also led to a higher proportion of loosely bound Al2O3 within the passivation film, resulting in a slight reduction in electrochemical corrosion performance. Remarkably, in a NaCl solution, the increased β/β′ phases significantly improved the MPEAs’ resistance to CE-C, attributed to the outstanding corrosion resistance and mechanical properties which could withstand elastic strain damage and plastic deformation.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
