Microstructure and electrochemical properties of Ti- containing AB2 type hydrogen storage electrode alloy
The microstructure and electrochemical properties variation of alloy Zr(MnVNi)2 after Ti substitution for Zr was investigated. The microstructures of Zr1ÿxTix (MnVNi)2 (x = 0, 0.5) alloys were determined with X-ray diraction (XRD), transmission electron microscopy (TEM), high resolution electron microscopy (HREM) and energy dispersive spectrum (EDS) analysis. The systematic structural analysis...
متن کاملPERFORMANCE OF AB, ALLOYS FOR HYDROGEN STORAGE AND HYDRIDE ELECTRODES
Two types of hydride electxodes are potential candidates to replace the Cd elecsode in NilCd batteries, One is of the A type where A is a rare earth metal or mixture thereof, and B is the transition metal. The other is commonly referred to as A type. A , type alloys with partial substitution of the B element in A type hydride material (Ovonic) with Co, Mn, Al, and Fe were studied (A compo...
متن کاملEFFECT OF MISH METAL TYPE ON THE MICROSTRUCTURE AND ABSORPTION/DESORPTION CHARACTERISTICS OF MMNI5 HYDROGEN STORAGE ALLOY
In this article, the effects of Pr and Nd were investigated on the microstructure and absorption/desorption characteristics of MmNi5 hydrogen storage alloy. The alloys were prepared in Vacuum induction furnace and the microstructures and phases were analyzed using scanning electron microscopy (SEM) equipped with energy dispersive X-ray analysis (EDS) and X-ray diffraction (XRD). Hydrogen absorp...

متن کاملHydrogen-enabled microstructure and fatigue strength engineering of titanium alloys
Traditionally, titanium alloys with satisfactory mechanical properties can only be produced via energy-intensive and costly wrought processes, while titanium alloys produced using low-cost powder metallurgy methods consistently result in inferior mechanical properties, especially low fatigue strength. Herein, we demonstrate a new microstructural engineering approach for producing low-cost titan...
