Composition and temperature influence on hydrogenation performance of TiZrHfMo_xNb_2–x high entropy alloys

Abstract

This study thoroughly investigates the influences of temperature and composition on the hydrogenation kinetic performance and discusses the hydrogen-induced phase transformation process at RT or high temperature of BCC TiZrHfMoxNb2–x (x = 0, 1, 2).

Future prospects of high-entropy alloys as next-generation industrial electrode materials

“…In general, the available and reported synthesis methods are broadly categorized as conventional, wet-chemical, and nonequilibrium synthesis methods (Table 7), which are discussed in the subsequent sections. 261–294…”

“…The annealing atmosphere, temperature, and time exhibit a significant influence on the structure of the HEA system. 277,278 Chen et al controlled the crystal structure of single-phase HEA NPs by altering the annealing temperature and inducing strain inside the lattice. 60 However, a strain within the HEA is developed that significantly improves catalytic performance.…”

Underlying factors of mega pressure hysteresis in cerium-rich CaCu5-type metal hydrides and effective modification strategies

“…6,7 Till date, hydrogen storage materials (HSMs) with varying crystal configurations have been explored, among which rare earth (RE)-based alloys with a CaCu 5 -type crystal structure stand out because of their high volumetric hydrogen storage capacity, room temperature de-/hydrogenation properties, and favorable PCT characteristics. 8–15…”
