为研究稀土在09CuPTi(RE)钢中的作用机理,首先需研究稀土分别与铜、磷、钛的相互作用。本文用固体电解质电池定氧、低温无水电解及等离子发射光谱等测试手段,研究了Fe-Cu-Ce,Fe-P-Ce,Fe-Ti-Ce溶液体系在1600℃平衡时溶质元素的相互作用规律。得到1600℃铁液中铈分别与铜、磷、钛相互作用系数e_(ce)~(cm),e_(ce)~P,e_(ce)~(Ti);观察到铈不与铜、磷、钛生成金属间化合物,而与微量氧、硫生成
In order to study the mechanism of rare earth in 09CuPTi (RE) steel, we first need to study the interaction of rare earth with copper, phosphorus and titanium respectively. In this paper, solid electrolyte battery oxygen, low temperature anhydrous electrolysis and plasma emission spectroscopy and other testing methods to study the Fe-Cu-Ce, Fe-P-Ce, Fe-Ti-Ce solution system at 1600 ℃ equilibrium of solute elements The law of action. The e_ (ce) ~ (cm), e_ (ce) ~ P, e_ (ce) ~ (Ti) of the interaction between cerium and copper, phosphorus and titanium in molten iron at 1600 ℃ were obtained. Titanium generates intermetallic compounds, with traces of oxygen and sulfur
