Multi principal element alloy (MPEA) corrosion database

Nick Birbilis,


The dataset includes information regarding the corrosion of MPEAs. It was compiled for a critical review paper submitted to Metallurgical and Materials Transactions A. Contributors to the database are different to the review paper authors, with the contributors to the database including those involved in data mining. The dataset has been processed to allow machine learning operations. This includes encoding the phases present in each alloy, and also parsing of alloy names/compositions into their individual elemental makeup (in atomic fraction). Input data includes alloy composition, phases, processing, test electrolyte type, test electrolyte concentration. Output data includes corrosion potential, pitting potential, corrosion current density, and calculated passive window.


Steps to reproduce

The data was gathered from the open literature. Each entry in the MPEA corrosion database has a corresponding link to the source paper/study. Empty cells in the database correspond to the data required for that cell not being provided in the associated study. The contributors have endeavoured to ensure the database is free of any errors.
