摘要：

Three dimensional atom probe (3DAP) with field ion microscope (FIM) was used to investigate Ni4Mo ordered alloy and the effect of pulse fraction on the experimental results obtained from 3DAP was studied. Antiphase boundary was observed in the alloy by FIM. An accurate chemical composition of Ni and Mo within a nano-space and a three dimensional atom position map with higher resolution were obtained at 20% pulse fraction. However, with the pulse fraction below 20%, the disparity between measured composition and academic composition grew larger as descending of the pulse fraction. No effect of pulse fraction was found on isotopic ratio and ionized electrovalence measuring.
