对经过中子辐照至注量6.6×10 23 n/m 2 (E>1 MeV)的钼单晶进行室温至600℃的拉伸试验。单晶通过二次重结晶制备并且具有接近<011>方向的轴向取向。与多晶样品相比，单晶样品因辐照而导致的屈服强度和脆化程度的增加更为明显。然而，渗碳单晶试样在辐照后的 DBTT 最低。
Tensile tests at room temperature to 600° C were performed on molybdenum single crystals which had been neutron irradiated to a fluence of 6.6× 10 23 n/m 2 (E> 1 MeV). The single crystals were prepared by means of secondary recrystallization and had axial orientations that were near to the< 011>-direction. The increase in yield strength and the degree of embrittlement that resulted from the irradiation was more pronounced for the single crystalline specimens than for the polycrystalline specimens. However, the carburized single-crystalline specimens had the lowest DBTT after irradiation.
