研究了掺杂不同量的磷和硫对IN718合金持久和保变性能的影响．结果发现，磷与硫之间存在有害的交互作用．这种交互作用削弱了磷的有益作用，增加了IN718合金对硫有害作用的敏感性．
The effects of doping different amounts of phosphorus and sulfur on the long-lasting and property-changeability of IN718 alloy were investigated. It was found that there was a detrimental interaction between phosphorus and sulfur. This interaction weakens the beneficial effect of phosphorus and increases the sensitivity of the IN718 alloy to the detrimental effects of sulfur.
