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 ...

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Prehistoric copper production and technological reproduction in the Khao Wong Prachan Valley of central Thailand [PDF]

, 2009
Employing a technological approach derived from the ‘Anthropology of Technology’ theoretical literature, this thesis concerns the identification and explanation of change in prehistoric extractive metallurgical behaviour in the Khao Wong Prachan Valley

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Effect of Casting Speed on Solidification Behavior and Porosity Defects in Low-Oxygen Copper Casting Rods Using SCR Technology

Journal of Manufacturing and Materials Processing
The Southwire Continuous Rod (SCR) process is widely used for producing low-oxygen copper rods, yet pore defects remain a significant challenge, affecting the performance and drawability of copper wire.

The Significance of the Rhetorical Ambiguity in Isaiah 54:16

Old Testament Essays, 2018
: The ambiguity in Isa 54:16a concerning the identity of the subject (YHWH or the smith) of the two verbs evoking a metallurgical action (to blow and to cast) is identified here as a rhetorical device intending to conceal the essential relation of YHWH ...

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.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
