Influence of the Different Rolling Temperatures on Microstructures and Mechanical Properties of IMI550 Alloy Bars

  • 摘要: 研究了3种轧制温度对IMI550钛合金ϕ22 mm棒材组织和力学性能的影响。实验对具有相同初始状态的原材料采用相同的轧制变形量,轧制温度分别为Tβ-60℃、Tβ-25℃、Tβ+15℃。试验结果表明:IMI550钛合金棒材经Tβ-60℃轧制后的组织为等轴组织,Tβ-25℃轧制后为双态组织,Tβ+15℃轧制后的组织为网篮组织;等轴组织、双态组织和网篮组织的室温和400℃高温拉伸强度没有明显变化,并且等轴组织和双态组织的塑性也相当,但网篮组织的塑性较差,网篮组织的蠕变性能最好,双态组织的其次,等轴组织的最差。
    Abstract: The effects of three rolling temperature on the microstructures and mechanical properties of IMI550 alloy ϕ22 mm bars were studied.Experimental raw material having the same amount of rolling deformation,but rolling temperatures were Tβ- 60℃,Tβ- 25 ℃ and Tβ+ 15 ℃.The results showed that the microstructure of IMI550 titanium bars rolling by Tβ- 60 ℃,Tβ-25 ℃ and Tβ+ 15 ℃ were equiaxed microstructure,duplex microstructure and basketweave microstructure respectively.The room temperature tensile strength and 400 ℃ high temperature tensile strength with equiaxed microstructure,duplex microstructure and basketweave microstructure did not show significant difference,and plastic of equiaxed microstructure and duplex microstructure were also similar.The plastic of basketweave microstructure is relatively poor,but the creep properties is the best,duplex microstructure is the second,equiaxed microstructure is the worst.
