Multi principal element alloy (MPEA) corrosion database

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.本数据集涵盖多主元合金（Multi-Principal Element Alloys, MPEAs）的腐蚀相关数据。其构建初衷是为提交至《冶金与材料汇刊A辑》（Metallurgical and Materials Transactions A）的一篇专题综述论文提供支撑。本数据集的贡献者与该综述论文的作者并非同一群体，其中包含参与数据挖掘工作的相关人员。 本数据集已完成预处理以适配机器学习操作，具体包括对各合金中存在的相进行编码，以及将合金名称或成分解析为各元素的原子分数组成。输入数据包含合金成分、相组成、制备工艺、试验用电解液类型以及试验用电解液浓度。输出数据则涵盖腐蚀电位、点蚀电位、腐蚀电流密度以及计算得到的钝化区间。
