摘要
MGH956合金为国内仿MA956合金研制的一种氧化物弥散强化高温合金,对MGH956合金板材进行了埃里克森杯突、拉深、扩孔、弯曲、锥杯和成形极限图等试验。通过试验,对于MGH956合金板材,建议采用具有拉深、胀形或拉胀复合成形特征零件的热成形,减少或避免用于具有较多翻边特征的零件加工。
MGH956 alloy is a kind of ODS superalloy that simulates MA956. MGH956 alloy pos- sesses many advantages： excellent higher temperature strength, antioxidation and anticorrosion. On the other while, the formability of this superalloy is bad. Some tests about formability of MGH956 alloy sheets are introduced. Through the experiment, hot forming is conformably form- ing process for MGH956 alloy sheets.
