Stasis or stimulus? Exotic materials and social display in Southeast Asia: Response to Pfaffenberger

Advances in Archaeomaterials, 2022
This paper assesses the relationship between metallurgy and social change in prehistoric Thailand. One model proposes that for about 15 centuries after circa 2000 BCE, peaceful village communities, being acquainted with copper-base metallurgy through ...

Study of hot deformation behavior of CuFe2 alloy [PDF]

, 2019
Nil strength temperature of 1062 degrees C and nil ductility temperature of 1040 degrees C were experimentally set for CuFe2 alloy. The highest formability at approx. 1020 degrees C is unusable due to massive grain coarsening.

Question of local exploitation of copper ore deposits in the Urnfield time in Poland

Frontiers in Earth Science, 2023
Despite rich deposits of copper in SW Poland, their exploitation in prehistory has not been confirmed, and in the literature it is usually argued that raw materials processed in the Bronze Age were imported.

Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

Advanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...
