高温钛合金Ti150是能在600 ℃环境下长期服役的新型高温钛合金,TC19钛合金是一种富β的α+β两相钛合金,具有高强度、高韧性的特点。采用Ti-21Cu-13Zr-9Ni(,wt,.%)非晶合金箔带作为钎料,进行了Ti150高温钛合金与TC19钛合金的真空钎焊连接工艺研究。通过扫描电镜分析接头组织,利用万能试验机测试接头室温和高温拉伸强度。结果表明:在930 ℃/35 min钎焊条件下,接头室温抗拉强度955.3 MPa,500 ℃高温抗拉强度达到540.0 MPa,550 ℃高温抗拉强度达到505.6 MPa,接头室温拉伸试样断裂于焊缝,断口总体为脆性断裂,接头高温500 ℃、550 ℃拉伸试样均断于Ti150基体上或近Ti150端面上,Ti150基体端断口有明显的延伸塑性变形。
High temperature titanium alloy Ti150 was developed for the aero-engines with high thrust-weight ratio and with long-term service temperature of 600 ℃. TC19 is a two-phase (α+β) titanium alloy with high strength and toughness. The vacuum brazing process of the two titanium alloys was conducted using Ti-21Cu-13Zr-9Ni(,wt,.%)as filler metal. The joint microstructure and element distribution of joint were analyzed by means of SEM and EDS, meanwhile the tensile strength of the joint was measured at the room temperature and high temperatures by universal testing machine. The results showed that under the brazing condition of 930 ℃/35 min, the joint tensile strength at room temperature reached up to 955.3 MPa, and the strength of 540.0 MPa and 505.6 was maintained at 500 ℃ and 550 ℃, respectively. The tensile specimens at room temperature fractured within the brazed seam and the fractured surface exhibited brittle characteristics. The tensile specimens fractured within the Ti150 metal substrate when tested at 500 ℃ and 550 ℃, and plastic deformation was observed at the fractured surface.
