A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, EarlyView.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6

Advanced Engineering Materials, Volume 28, Issue 4, 18 February 2026.
The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

The capability enhancement of aluminium casting process by application of the novel CRIMSON method [PDF]

, 2011
The conventional foundry not only frequently uses batch melting, where the aluminium alloys are melted and held in a furnace for long time, sometimes as long as a complete shift, but also uses the gravity sand casting process where the molten aluminium

GATHERING THE HARVEST: THE COLLECTION AND TRANSPORTATION OF AGRICULTURAL PRODUCE IN ROMAN CAMBRIDGESHIRE AND PETERBOROUGH

Oxford Journal of Archaeology, Volume 45, Issue 1, Page 68-92, February 2026.
Summary When Rome colonized Britain, it created a transport network spanning the province. This transformed the Iron Age economy, creating large new markets which in turn supported specialized manufacturing. This article explores the impact of transportation on Roman agriculture – the core of the Romano‐British economy.
