説明
In order to understand a genetic trend of the microsegregation quantitatively measured by EPMA in transformation of titanium alloys, experiments on the effect of cooling rate from β phase and contents of the alloying element such as Fe and Cr were carried out on Ti-Fe and Ti-Cr binary alloys and on Ti-5Al-2Cr-1Fe alloy.<BR>As a result of the experiment and the examination with parameters such as the segregation index, the effective distribution coefficient and the β stabilizing rate, the genetic trend of the segregation for Fe was larger than Cr and there was a sort of a critical cooling rate under the effect of cooling rate from the β phase.<BR>Electron absorption images showed that this kind of segregation had a certain small area and distributed and scattered around. It was found that the less contents of β stabilizing elements, the larger the genetic trend of the microsegregation, and the trend was reduced with increasing degree of the β stabilizing in the alloys. It was also shown that the genetic trend of the microsegregation on 1 wt%Fe in Ti-5Al-2Cr-1Fe alloy was smaller than that on 1 wt%Fe in Ti-1Fe binary alloy, and that was in the other way on 2 wt%Cr in Ti-5Al-2Cr-1Fe and Ti-2Cr alloys.
