研究了一种高NbTiAl基合金两种组织状态下的热压缩性能及高温抗氧化性能。结果表明 ,片层组织合金比双态组织合金具有较高的高温抗压强度和屈服强度 ,而塑性较差。Nb的加入有效地提高了TiAl合金的抗氧化性
The hot compressive properties and high temperature oxidation resistance of a high NbTiAl-based alloy were studied. The results show that the lamellar alloy has higher high temperature compressive strength and yield strength than the binary alloy, but the plasticity is poor. The addition of Nb effectively improves the oxidation resistance of TiAl alloy
