steel research international, EarlyView.This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

Quality from Kent: Preliminary results from the analysis of fifth‐ to seventh‐century silver alloys
Archaeometry, EarlyView.Abstract This paper explores early results from the chemical and lead isotope analysis of 30 silver‐alloy objects from southeast England dating between the fifth and seventh centuries CE, presenting limited aspects of the three main analyses that were conducted. First, a comparison of the results gained from surface x‐ray fluorescence (pXRF) values and

ANTIMONY LEACHING FROM STIBNITE AND COMPLEX ORE
Journal American Society of Mining and Reclamation, 2006 To shed light on the leaching of Sb from mine wastes containing stibnite, two series of experiments were conducted. In one experiment, polished slabs of a museum-grade stibnite and a mixed-sulfide ore sample containing 28% Sb were subjected to accelerated weathering at 100% humidity and 31-35C for 37-44 days.

The Provenance of Silver in the Viking‐Age Hoard From Bedale, North Yorkshire
Archaeometry, EarlyView.ABSTRACT The acquisition of silver was a key motive propelling the Viking expansion out of Scandinavia; identifying the sources of Viking silver during the early part of the Viking Age can provide critical insights into the relative significance of western European and eastern, Islamic wealth in the Viking expansion.

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 ...

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)
Archaeometry, EarlyView.ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...
