| 摘 要： | 以高纯氮化硼（BN）作为坩埚材料，对其应用于TiNi系合金熔炼时的界面反应进行研究.研究BN在不同温度下（1 450 ℃，1 520 ℃），保持一定时间（90s,180 s,270 s,360 s）与TiNi系合金熔体的相互作用情况，得到了不同反应时间、反应温度下的界面层，并用扫描电子显微镜（scanning electron microscopy, SEM）、X射线衍射（X ray diffraction, XRD）和电子探针显微分析(electron probe microanalysis, EPMA)对界面进行形貌、物相和成分的分析，对反应机理作了讨论.研究结果表明，BN与熔体作用的产物在试验条件下不与熔体继续反应，从而保护了熔体不受到进一步污染.

| Abstract: | Interaction between high-purity boron nitride (BN) and melted TiNi alloy was studied to determine if BN could be used as crucible material for melting TiNi alloy. A series of interface actions between them were performed for differentmelt temperatures (1 450 °C, 1 520 °C) and different holding times (90 s, 180 s, 270 s, 360 s). These interfaces were then investigated with scanning electron microscopy (SEM), X-ray diffraction, and electron probe microanalysis. The results showed that TiNi melt was slightly contaminated due to the limited reaction between BN and Ti under the conditions. |
