Abstract:Large-scale scanning of casting brass ZHPb59-1 was achieved with metal original position analyzer, and the distribution of additive elements in alloy including Zn, P, Mn, Al, Si, Fe, Pb, Ti and B was analyzed by original position statistic distribution analysis. It was expected to provide a rapid analysis method for surface element distribution in copper alloy industry. The intuitive distribution image, the maximum segregation degree, the maximum segregation position and statistic segregation degree of elements could be rapidly obtained by original position scanning technology. It was found that, the distribution of Zn, P and Mn and their impact on the organization obtained by original position analysis were in good agreement with those by metallography. The two dimensional and three dimensional distribution maps showed that, the distribution of Al, Si and Fe was more uniform. It could be inferred from original position statistic distribution that, there were a large number of inclusion phases of Pb, while P was dispersed in whole alloy; as main alterant, there was obvious segregation for Ti and B. Moreover, the original position statistic results of Cu and P were accordant with those obtained by scanning electron microscope and energy spectrum analysis.
