چکیده
The archaeometallurgy of copper have been pioneer technologies in ancient Iran and goes back to about ten thousand years ago in Iranian Plateau [1, 2]. The Haft Tappeh Middle Elamite Site is located in Southwest Iran and have been an important city belonging to early phase of Middle Elamite period (14th century BCE) [3, 4]. Based on various metallurgical evidences found in archaeological excavations, such as metalworking workshop, slag, smelted copper as well as numerous copper alloy artefacts, extensive metallurgical activities have done in Haft Tappeh and it has been an important center in smelting and manufacturing copper alloys in second millennium BC [4, 5]. To identify metallurgical process of metallic artefacts in Haft Tappeh including alloying composition, inclusions and phases as well as manufacturing and shaping, seven metallic fragments have studied by Scanning Electron Microscopy with Energy Dispersive X-ray Spectrometry (SEM-EDS) and optical microscopy.

The study of cultural heritage artifacts and the research of a protection and restoration intervention create with - and are often limited to - a complete characterization of their surface. This is not only factual for museum objects, but also for archaeological artifacts, because the object as it was discovered may contain precious unknown information that could be lost by too much aggressive ...

Background: A microscopic study on ancient metals was established to identify chemical composition and microstructure of archaeological tin bronze objects. For this purpose, ten small bronze pieces from Baba Jilan Iron Age site, western Iran, were selected and studied by optical microscopy (OM) and scanning electron microscopy–energy dispersive X-ray spectroscopy (SEM–EDS) methods. Results: The...

Nowadays, equal channel angular pressing, known as the ECAP process, is one of the most popular methods for manufacturing ultra-fine grained (UFG) materials. In this paper, Ecap process has been carried out on pure copper and 6012 aluminum alloy up to six passes by route . Principal attention was paid to the influence of parameters such as diameter, material, and the height of billet on mechani...
