采用多级快速凝固制粉装置制各ＲＳＰＡｌ－Ｆｅ－Ｖ－ＳｉＦＶＳ０８１２合金粉，运用ＴＥＭ，ＸＲＤ对合金冷轧板高温稳定性进行了研究．结果表明；在５５０℃下长时间退火，合金仍保持相当高的硬度；在６００℃下退火１２ｈ，可观察到再结晶发生，并伴随有｛１１０｝再结晶织构出现．合金中大量的第２相粒子延缓了再结晶的发生，提高了组织与性能的稳定性
The RSPAl-Fe-V-SiFVS0812 alloy powder was prepared by multi-stage rapid solidification pulverizing equipment, and the high temperature stability of cold-rolled alloy sheet was studied by TEM and XRD. The results show that the alloy retains a relatively high hardness after annealing at 550 ℃ for a long time. The recrystallization occurs with annealing at 600 ℃ for 12h, accompanied by the {110} recrystallization texture. A large number of second phase particles in the alloy delay recrystallization and improve the stability of the microstructure and properties
