Study on the morphology and distribution of Fe phase in solidification structure of Cu-15Fe alloy ingots
Source abstract
Abstract
Abstract The realization of high strength of copper-iron (Cu-Fe) alloy is related to its solidification structure. The morphology and distribution characteristics of Fe phase in the solidification structure of Cu-15Fe alloy ingot were analyzed, and the deformation strength of the alloy was compared. The results show that the cooling conditions can affect the size, morphology and distribution of Fe phase in the solidified structure. The average distribution uniformity in the water-cooled copper mold ingot (W-ingot) is 0.45% higher than that in the quartz mold ingot (Q-ingot). The distribution quality of Fe phase in solidification structure can be evaluated by fractal dimension and average Fe phase area. The larger the fractal dimension is, the smaller the average Fe phase area is, where Fe phase is smaller and more uniform in the corresponding region. In the experiment, the strength of the strip increased from 510 to 547 Mpa corresponds to the Q-ingot and the W-ingot.
