Metallurgical techniques, such as metallographic examination, are seldom reported as being used in forensic science investigations. In these cases, most findings related to the metal's nature rely on visual and chemical examinations. The potential of applying metallurgical techniques to forensic science investigations is illustrated by means of two case histories. The information needed to establish a link between different pieces of metal is obtained from a metallographic examination of the metal's microstructure which reflects its thermomechanical history. It is shown that this kind of information is unique and cannot be obtained by applying conventional techniques such as chemical analysis. It is therefore concluded that metallurgical techniques can successfully complement other scientific techniques commonly employed in the forensic science context.
