Ar离子辐照导致微球玻璃机械性能的变化

为研究离子辐照导致空心玻璃微球机械性能的变化，利用Ar离子辐照与空心玻璃微球组分相同的微球玻璃薄片，结合不同温度下的等时退火处理，采用纳米压痕测试方法研究了辐照前后玻璃机械性能的变化。测试结果表明：辐照后玻璃的硬度和模量均呈下降趋势，恢复阻力明显升高；退火后的未辐照样品硬度和模量呈上升趋势，恢复阻力在误差范围内没有发生变化; 退火后的模量呈下降趋势，恢复阻力呈下降趋势；在退火温度约为300 ℃时，辐照样品退火后的恢复阻力与未辐照样品基本相同。

Mechanical property modifications of microsphere glass induced by Ar ion irradiation

In order to study the mechanical properties of ion irradiated hollow glass microspheres, the glass sample with the same composition of the hollow glass microspheres was irradiated by Ar ions. Combining with the annealing treatment, the mechanical properties of microsphere glass were studied by means of nanoindentation. The results show that the hardness and modulus of the microsphere glass are decreased after ion irradiation, and the recovery resistance is obviously increased. After annealing, the hardness and modulus of unirradiated samples showed an upward trend, and the recovery resistance did not change within the error range; the hardness of the irradiated microsphere glass is increased, while the modulus and the recovery resistance are significantly decreased. After annealing at around 300 ℃, the recovery resistance of the irradiated sample is the same as the unirradiated sample within the error range.
