Abstract
This article reviews the phase diagrams, alloy with third element additions, layer growth, critical current density, and matrix materials of A15 superconductors. It describes the production methods of tape conductors (chloride deposition, and surface diffusion) and multifilamentary wires (rod process, modified jelly roll process, niobium tube process, in-situ process, powder metallurgy process, and jelly roll method). The article focuses on reaction heat treatment, which is required at the end of wire processing to convert the ductile components to the desired, but brittle, superconductor. Finally, it discusses the applications of A15 superconductors in commercial magnets, power generation, power transmission, high-energy physics, and fusion.
