摘　　要：摘要:通过HZB串列加速器用18MeV质子研究了ZrSnNb合金的辐照效应。结果表明,经1.53×1014cm-2注量的质子辐照后,辐照产生的缺陷使样品的显微硬度升高导致辐照硬化;断口分析发现辐照后在样品的一端韧窝明显变小出现脆化现象,被认为是由于质子辐照离子化损伤产生在其射程的末端——与TRIM96程序计算的结果一致。The Zr-Sn-Nb alloy specimens were irradiated using a tandem accelerator by 18 MeV proton at room temperature to total proton fluence of 1.53×1014 cm-2 at 1 mm depth. It was observed that microscopic hardness was increased by proton irradiation. The results of tension test and fractograph showed that the proton irradiation induces a hardening and a ductile reduction. The increasing imperfection by proton irradiation was thought to be major reason of these phenomena.
