For experimental validation we chose materials that were lying on or near the Pareto front, similar to previous successful HEA hydrides, and/or had a high ratio of predicted H/M to formula weight (i.e., high gravimetric capacity for its H/M ratio). The materials selected for experimental testing in this study include MgTiVZrNbHf, MgTiVCrNb, and MgAl-TiVCr. Another interesting Pareto front material is the low-cost, low-weight MgTiCrMn.
