Abstract
The element concentration can be measured quickly and with high precision in situ for melts using electron beam energy. Starting from the characteristic X radiation of the elements contained in the melt, measuring phases are integrated in the melt process at specific time intervals. During this time, the melt regime is modified in order to perform an X-ray analysis of the concentration measurement. The process is applied to alloy melts.
