The composite processing technology of Nb-Ti superconducting materials
Superconducting materials are widely used in many fields due to their unique properties, such as zero electrical resistance, high temperature superconductivity and so on. Among them, Nb-Ti alloys are the most widely used and w......
Rolling in vacuum and protective gas
Rolling in Vacuum and Protective Atmosphere
Introduction
Rolling is the process of reducing the thickness of a metal workpiece by passing it through a pair of rotating metal rolls (rollers); when heated and subjected to amplification, it also increases its length. It is one of the most widely us......
High temperature superconductor bulk structure
High-temperature superconducting block materials (HTSB) have been widely used in a variety of applications and devices in the past several decades. Because of their superior electrical and thermal properties, HTSB materials are ideal for high-performance electronic devices and equipment. The micro......
