摘要
介绍了钼和钼-铌单晶的制备原理、制备工艺及电子束区域熔炼炉组成结构。对熔炼室真空度、聚焦、原料棒化学成分、尺寸规格、熔炼速度,搅拌速度等对单品制备的影响进行了详细分析。
Preparing principle and preparation technology of Mo and Mo - Nb alloy single crystal and structure and component of electron beam floating zone melting are introduced. Influences of vacuum in the melting chamber, chemical composition and specifications of Mo and Mo - Nb alloy feed stock bar growing rate, rotation rate on pro- cessing Mo- Nb alloy are analyzed in detail.
