Production of arsenical bronze using speiss on the Elephantine Island (Aswan, Egypt) during the Middle Kingdom (Middle Bronze Age) (c.2000–1650 BCE)

open access: yesArchaeometry, EarlyView.
Abstract This paper presents the first direct evidence of the slags produced during the cementation alloying process of Cu with speiss inside ceramic crucibles, thus representing Cu alloying with As in Middle Kingdom Egypt. The settlement deposits from the Middle Bronze Age were excavated on Elephantine Island, within modern Aswan.

Delineation of the reaction mechanism of Ti2AlC MAX‐phase formation during spark plasma sintering synthesis

open access: yesJournal of the American Ceramic Society, EarlyView.
Reaction mechanism governing Ti2AlC MAX‐phase formation from elemental 2Ti:Al:C powder mixture during spark plasma synthesis was delineated through in‐depth microstructural characterizations using HTDSC, XRD, SEM–EDS–EBSD and elucidated by density functional theory (DFT)‐based ab initio calculations.

Some Statistics on Intermetallic Compounds

Inorganic Chemistry, 2014
It is still largely unknown why intermetallic phases show such a large variety of crystal structures, with unit cell sizes varying between 1 and more than 20 000 atoms. The goal of our study was, therefore, to get a general overview of the symmetries, unit cell sizes, stoichiometries, most frequent structure types, and their stability fields based on ...
