Abstract

This paper characterized a fracture brass sample that underwent tensile testing. The aim of the case study is to characterized the brass sample with unknown microstructural arrangement and unknown elements composition. Tests were conducted based on the SEM imaging technique, EDX chemical analysis and XRD microstructural spatial analysis to indentify and correlate evidence on the sample. Examinations by morphological SEM analysis of tensile fracture surface shows that the brass sample exhibit a typical ductile like material fracture. XRD analysis confirmed the crystal arrangement of the brass sample is of a single FCC??-phase crystal arrangement. The brass composition is confirmed as 63Cu:37Zn wt% from the test conducted by the XRD analysis. The sample is suspected to undergone annealing for process history from the evidence on twinning on the cross-sectional SEM imaging. Thus it can be confirmed that material is a brass sample with 63Cu:37Zn wt% elemental composition with single FCC-phase crystal arrangement.
