微量硼在钢中的作用与其在钢中存在的形式、结构及微观分布有着极其密切的关系。但是,由于硼的原子序数很小,钢中含量又极微(约几十ppm),因此难以观察和测试。α粒子显微径迹照像技术较圆满地解决了这一问题。我们在研究硼在钢中的作用时利用了这一实验技术并结合我们的具体情况进行了改进,特别是在使α粒子径迹像与显微组织的结合方面作了一些工作并取得了一些新的结果,为深入探索硼在钢中的作用机制提供了新的手段。
The role of trace boron in steel is closely related to its form, structure and microscopic distribution in steel. However, due to the small atomic number of boron, the content of the steel is very small (about a few dozen ppm), so it is difficult to observe and test. Alpha particle microscopic track imaging technology to more satisfactorily solve this problem. We used this experimental technique in our study of the role of boron in steel and improved it in the light of our specific circumstances, particularly in the area of binding of α-particle trajectories to microstructures and achieved some The new results provide new tools for further exploring the mechanism of boron in steel.
