真空感应熔炼用石墨坩埚对Ni47Ti44Nb9形状记忆合金质量的影响
The Influence of Crucible Graphite on the Quality of Ni47Ti44Nb9 Shape Memory Alloys During the Vacuum Induction Melting Process
摘要
Abstract
The performance of three different kinds of crucible graphite materials used during vacuum inductive melting of Ni47Ti44Nb9 shape memory alloys (SMAs) was explored. One low-density extruded graphite and two isostatically pressed graphite-materials with different porosity and purity were used for melting NL47Ti44Nb9-SMAs from pure Ni,Ti and Nb raw materials. The use of a low grade, lower density graphite crucible led to a high carbon contamination of the alloy ingot. Much better results were obtained using graphite crucibles with higher density and higher purity.关键词
