径迹显微照相技术是利用硼的同位素(~(10)B)所特有的中子核反应,以塑料等固体径迹探测器加以检测,而发展起来的一项近代试验方法。它能定量测定材料中微量硼的分布状态及其在各种加工、热处理条件下的变化。它与金属物理的其它试验技术相配合,是深入研究硼的作用机理,硼钢组织,结构与性能之间关系的重要手段。发展含硼材料系列是发展我国自己材料体系的一个重要方面。但硼在钢中的作用很复杂,研究硼在钢中作用规律方面,人们虽已进行了大量工作。但是,长期以来,由于实验技术的限制,一直未能很好解决。由于微量硼的作用不仅与其含量,更主要的是其在钢中的显微分布状态有密切关系,因此迫切要求有一种能直接观察的有效手段来加以研究。
Trajectomic micrography is a modern test developed by using neutron nuclear reactions characteristic of boron isotopes (~ (10) B) and detected by solid track detectors such as plastics. It can quantitatively determine the distribution of trace boron in materials and its changes under various processing and heat treatment conditions. It cooperates with other experimental techniques of metal physics and is an important means to deeply study the mechanism of action of boron and the relationship between structure and properties of boron steel. The development of a series of boron-containing materials is an important aspect of developing our own material system. However, the role of boron in steel is very complex. Although many studies have been conducted on the law of boron in steel, a great deal of work has been done. However, due to the limitation of experimental techniques, it has not been solved well for a long time. Since the role of trace boron is not only closely related to its content, but also its microscopic distribution in steel, there is an urgent need for an effective means of direct observation to be studied.
