摘　　要：通过在室温下进行摆锤冲击试验,测量了Ti13Nb13Zr合金在冲击能量作用下的能量吸收与变形情况。通过使用不同形状缺口的试件与改变冲击能量,确定这两个因素对试验结果的影响。结果表明,在冲击能量相同的情况下,不同形状缺口仅对试件冲击力和吸收功数值有影响,相同缺口的试件随着冲击能量的不断增加,冲击力和吸收功也不断增加,但增加幅度较小。在所述试验条件下,所有的试件都发生脆性断裂,侧膨胀值很小。Through pendulum impact tests at room temperature, the energy absorption and deformation of Ti13Nb13Zr alloy under the action of impact energy are measured. By using samples with different notch shapes and varying the impact energy, the influence of these two factors on the test results is determined. The results show that, under the same impact energy, different shapes of notches only have an effect on the values of impact force and absorbed energy of the samples, and for the samples with the same notch, the impact force and absorbed energy increase with the continuous increase of the impact energy, but with a small amplitude. Under the specified test conditions, all samples experience brittle fracture with small lateral expansion.
