铜稳定多芯铌三锡超导材料是由无氧铜-铌-磷青铜-青铜-铌芯等多层金属组成的一种新型的复合材料,它应用于高能物理、受控热核聚变反应、磁流体发电、电机、输电、磁浮列车、舰船推进等各个领域。为了研究它的微观结构,必须进行金相观察,由于这些金属的加工硬化特性不同,给制备金相试样带来了一定困难。经过摸索,我们认为采用下述工艺可以制备出较为满意的金相样品。一镶样先取φ10×1mm的铜管车成10mm高的镶样套管。将套管放在平面玻璃板上,中间用一层描图纸隔
Copper stabilized multi-core niobium tin tin superconducting material is a new composite material composed of multi-layer metal such as oxygen-free copper-niobium-phosphor bronze-bronze-niobium core, which is applied to high energy physics, controlled thermonuclear fusion reaction , Magnetic fluid power generation, motor, transmission, maglev train, ship propulsion and other fields. In order to study its microstructure, the metallographic observation must be carried out. Due to the different work hardening properties of these metals, certain difficulties are brought about in the preparation of metallographic samples. After exploration, we believe that the following process can be used to prepare more satisfactory metallographic samples. A sample of the first take φ10 × 1mm copper tube into a 10mm high mounted casing. The casing on the flat glass, the middle with a layer of tracing paper
