摘要

材料的消耗与日俱增,这意味着我们将不得不越来越多地应对自然资源和供应问题。因此,人类不得不扩大资源基础,设法更有效地利用现有的原材料,将以前无法使用的物质转化为有用的材料,并从大量存在的物质中生产出全新的材料。制造新材料的方法之一是用带电离子照射物质。文章讨论了基于级联-概率方法的这一技术,其目的是获得级联-概率函数(CPF),并在考虑离子能量损失的情况下进行下一步使用。CPF 计算的执行取决于碰撞次数和对各种入射离子和样本的监视深度。在计算级联概率函数和空位簇的空间分布时,获得了金银合金的传导模式并找到了真正的结果区域。计算步骤和边界的选择是自动化的。计算结果以图表形式展示。

Modeling of radiation processes of defect formation in materials irradiated with ions
The consumption of materials is growing every day, which means that we will increasingly have to cope with the problems of natural resources and supply. Therefore, humanity is forced to expand its resource base finding ways to use existing raw materials more efficiently, turn previously unusable substances into useful materials and also produce completely new materials from substances that are available in abundance. One of the ways to create new materials is to irradiate a substance with charged ions. The article discusses this technique based on the cascade-probabilistic method, the purpose of which is to obtain as well as the next ensuing use of cascade-probabilistic functions (CPF) considering energy losses for ions. The CPF computations were executed depending on the number of collisions and the depth of surveillance for various incident ions and samples. When computing cascade-probabilistic functions and spatial distributions of vacancy clusters patterns of conduct and finding the real resulting region in gold and silver alloys were obtained. Selection of step and boundaries for calculation were automated. Results of the calculations performed are illustrated in the form of graphs and tables.
