通过X射线(XRD)、示差扫描量热分析(DSC)和电阻率的变化研究了质子辐射照对Zr41.5Ti14.9Cu12.6Ni10.5Be20.4大块非晶合金结构弛豫的影响。结果表明,在203K时,以质子的能量为160keV、剂量为1.65×1016粒子/cm2辐照后,Zr41.5Ti14.9Cu12.6Ni10.5Be20.4大块非晶合金发生了明显的结构弛豫;而经质子能量为160keV、剂量为1.1×1015粒子/cm2和能量为120 keV、剂量为6.5×1015粒子/cm2辐照后,Zr41.5Ti14.9Cu12.6Ni10.5Be20.4大块非晶合金形成了更稳定的玻璃态。
The effect of proton radiation on the structure relaxation of Zr41.5Ti14.9Cu12.6Ni10.5Be20.4 bulk amorphous alloy was studied by X-ray diffraction (XRD), differential scanning calorimetry (DSC) and resistivity. The results show that significant structural relaxation of Zr41.5Ti14.9Cu12.6Ni10.5Be20.4 bulk amorphous alloy occurs at 203K with proton energy of 160keV and irradiation dose of 1.65 × 1016 particles / cm2. However, the formation of Zr41.5Ti14.9Cu12.6Ni10.5Be20.4 bulk amorphous alloy with proton energy of 160 keV, dose of 1.1 × 10 15 particles / cm 2 and energy of 120 keV at a dose of 6.5 × 10 15 particles / cm 2 A more stable glassy state.
