Macroscopic and microscopic radiation effects on glass materials
Abstract
<p indent="0mm">Glass materials are crucial in fields including nuclear industry, aerospace, and deep space exploration but can have a significant impact on the materials, leading to severe issues such as color changes, increased brittleness, and a reduction in optical performance. The fundamental challenge in designing irradiation-resistant glass is gaining an understanding of the macroscopic and microscopic physical processes involved in irradiation damage. Despite its importance, a few papers provide an in-depth and systematic discussion of this critical issue. We aim to address this gap in the literature. First, we explore the atomic-level physics of displacement and ion damages caused by irradiation. Next, we discuss the formation mechanism of color center defects in glass. Subsequently, we summarize the changes in the optical, mechanical, and thermal properties resulting from damage evolution. Furthermore, we discuss experimental monitoring methods for irradiation damage types and multiscale simulation and modeling methods for macroscopic and microscopic irradiation damage of glass material. This paper is a roadmap for the design of radiation-resistant or radiation-tolerant glass.</p>
