摘要：

The effects of 100 keV He ion irradiation on the mechanical properties of molybdenum single crystals were studied by examining the temperature- and dose-dependence of tensile behavior at 77 and 293 K. The yield stress of single crystals increased with increasing dose and the fracture stress decreased with increasing dose at 77 K. A ductility loss occurred in irradiated crystals at 293 K. These results show that the surface damage layer about 200 nm thick causes embrittlement at low temperatures and ductility loss at higher temperatures.
