摘要
研究了宝鸡钛业股份有限公司生产的BT8钛合金在不同轧制工艺下棒材的组织与性能。不同显微组织的BT8轧棒的室温性能为:Rm≥1075 MPa,RP0.2≥983 MPa,A≥13%~17%,Z≥22%~45%;500℃拉伸性能:σb≥748 MPa^768 MPa,σ0.2≥595 MPa^610 MPa,δ≥19%~23%,ψ≥65%~71%。研究表明该合金具有良好的综合性能。
Microstructures and properties of BT8 titanium alloy rolled bars developed by Baoji Titanium Industry Co., Ltd. are introduced. The properties of the bars with different microstructures are shown as follows： at room temperature： Rm≥ 1075 MPa, Rp0.2≥983 MPa, A≥ 13%-17%, Z≥22%-45%; at 500℃ σb≥748 MPa≥768 MPa, σ0.2≥595 MPa-610 MPa, δ≥ 19%-23%, ψ≥65%-71%. The results show that BT8 alloy has good combined mechanical properties.
