Abstract

The effect of neutron irradiation on the mechanical properties of commercially pure iron upon plastic deformation at elevated temperatures has been studied. The interaction of impurity atoms with radiation-induced defects has been found to suppress dynamic strain aging. A significant decrease in plasticity due to blue brittleness has not been observed in the samples irradiated by neutrons. High-energy particles have also been revealed to increase the plasticity of irradiated Armco iron and the number of microstructural deformation mechanisms during plastic flow at elevated temperatures.

中子辐照 Armco 铁在高温塑性变形时的力学性能

摘要

已经研究了中子辐照对商业纯铁在高温下塑性变形时的机械性能的影响。已发现杂质原子与辐射引起的缺陷的相互作用可抑制动态应变老化。在中子辐照的样品中没有观察到由于蓝脆性导致的塑性显着降低。还发现高能粒子可以增加辐照 Armco 铁的可塑性和高温下塑性流动过程中微观结构变形机制的数量。
