STUDY TROUGH METALLOGRAPHICAL METHOD AND X-RAY FLUORESCENCE<br /> TECHNIQUE, ON THE SOME ROMAN BROOCHES DISCOVERED AT TOMIS-CONSTANTA
Journal Title: Journal of Science And Arts - Year 2008, Vol 9, Issue 2
Abstract
XRF method was used at the same time with a metallographic study in order to determine the concentration of the main compounds of raw materials and, in the same time, of the alloy types used in the ancient period. It was also tried a quality classification of these alloy types in the attempt of watching a development of processing and implicitly, of these objects making techniques.
