Zr alloys have been broadly used as cladding materials in fission reactors since 1950s [1, 2]. A universal degradation issue in this field is the oxidation of Zr cladding materials, which has been widely investigated in the past decades [3-5], but there is insufficient understanding of hydrogen ingress process during corrosion due to the fundamental difficulties in hydrogen detection. Atom...
In the burgeoning field of hydrogen energy, compositionally complex alloys promise unprecedented solid-state hydrogen storage applications. However, compositionally complex alloys are facing one main challenge: reducing alloy density and increasing hydrogen storage capacity. Here, we report TiMgLi-based compositionally complex alloys with ultralow alloy density and significant room-temperature...
Martensitic advanced high strength steel (MS-AHSS), specifically MS1500, is an identified steel for various applications in the automotive industry to reduce the car weight improving fuel economy without compromising structural integrity. Nevertheless, hydrogen embrittlement (HE) is an issue with MS-AHSS. The HE susceptibility is affected by a number of the steel’s characteristics including...
