本文利用透射电镜观察了HR-2及SS321不锈钢注入He~+并在T<1023K不同温度退火后的He泡结构,发现T=0.45T_m是一个转变点,当0.3T_m0.45T_m时,He泡主要通过迁移和合并而长大,长大激活能的实验值分别为0.41e...

Ta and C ions extracted from a MEVVA ion source were implanted into Cr12 steel, with an implantation dose of (1-5)x1017cm-2, extraction acceleration 42kV, and average ion beam flux about 20-50μA·cm-2. Rutherford backscattering spectrum (RBS) was used to measure the surface composition after Ta and T...
