4.1. Volume Fraction of Complex Compounds Precipitated during Solution Treatment
Reports are available on the presence of the complex precipitates in several HSLA steels,like Nb-V,V-Ti and Nb-Ti bearing steels and on the thermodynamic analysis of the complex compounds. However there are few research on the complex precipitates from the viewpoint of comparison between experimental results and theoretical analysls on both chemistry and volume fraction of precipitates.
An example of complex precipitates formed in O.028%Nb-0.048%Ti steel (A1) which was reheated to 1250'C for 5h is shown in FIG.5 . The energy dispersive X-ray (EDX) from the particle (indicated by an arrow) shown in FIG.5 indicates the sharp peaks of both Nb and Ti, while the electron diffraction pattern of the particle shown in FIG.5 indicates the single crystal of B1 rock salt structure. This suggests that Nb and Ti were mutually significantly soluble in the precipitates, as previously reported.FIGURE,6 shows the calculated and microanalyzed composition for the precipitate particles in 0.028%Nb-0.048%Ti (A1)and O.027%Nt-0.063%Ti steel (A2) reheated at a temperature between 900 and 1250'C. The experirnental data of composition (Nb/(Nb+Ti) ratio) in precipitates were mesured from 8 to 10 particles for each specimen by EDX microanalysis and denoted by error bars in the figure. The calculated results of microalloys (Nb/(Nb +Ti)) and interstitial elements (C/(C+N)) by the present model are denoted by solid line and broken line, respectlvely. It is shown that the measured value of Nb/(Nb+Ti) ratio varied from 0.1 to 0.3 with the peak at about 1100'C in both steels. The calculation predicts the complete mixing of Nb and Ti in precipitates and the tendency to form a TiN-rich compoundat higher temperature. The calculated Nb/(Nb+Tl) ratio by the present model is good agreement with the measured one, especially on the presence of the peak at about 1100'C in both steels.

这个太专业了,我大致帮你翻译了一下,仅供参考:
在解答治疗报告期间被沉淀的复杂化合物的体积分数
是可利用的在复杂沉淀物的出现在几HSLA钢，像Nb-V，V钛和Nb钛轴承钢和在对复杂化合物的热力学分析。 有对复杂沉淀物的少量研究从比较观点在实验性结果和理论分析之间在化学和沉淀物的体积分数。
复合体沉淀物的例子在被重新加热对1250年' C为5h的O.028%Nb-0.048%Ti钢形成的(A1)显示在。 能量分散性X-射线(EDX)从微粒(表示由箭头)显示在表明Nb和钛锋利的峰顶， 当微粒的电子绕射图显示在时表明B1岩盐结构单晶。 这建议Nb和钛是相互显著可溶解的在沉淀物， 如早先报告。图， 6个展示计算并且显微镜分析其构成为沉淀物微粒在0.028%Nb-0.048%Ti (A1)，并且O.027%Nt-0.063%Ti钢(A2)重新了加热在一个温度在900和1250年' C之间。 构成(Nb/实验数据 (Nb+Ti)比率)在沉淀物是由EDX微量分析测量从8个到10个微粒为每个标本并且因失误表示了酒吧在图。 微合金(Nb/的故意的结果(Nb +Ti)) 并且细胞间的元素(C/(C+N)) 由当前模型由实线和断线表示个别的。 它显示Nb/的测量值(Nb+Ti)比率在两钢变化了从0.1到0.3与峰顶在大约1100年' C。 演算在沉淀物预言完全混合Nb和钛和倾向形成一个富有锡的混合物更高的温度。 故意的Nb/(Nb+Tl)比率由当前模型是与被测量的一个的利益协定， 特别是在峰顶的出现在大约1100年' C在两钢。
