Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

open access: yessteel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.

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.

An Archaeometallurgical Investigation on Some Archaeological Metal Finds From the Sasanian Site of Jahāngir, Western Iran

open access: yesArchaeometry, EarlyView.
ABSTRACT Twelve metal artifacts from recent excavations at the Sasanian archaeological site of Jahāngir in western Iran have been analyzed. These items include both decorative and utilitarian artifacts. The samples were examined using micro‐X‐ray fluorescence (μ‐XRF), scanning electron microscopy with energy‐dispersive X‐ray spectroscopy (SEM‐EDS), and

A comparison between single sided friction stir welded and submerged arc welded DH36 steel thin plate [PDF]

open access: yes, 2012
The adoption of the friction stir welding (FSW) process into the shipbuilding industry is being considered as a medium term issue. Currently the data on friction stir welded mild steels tends to be fragmented, with critical areas being short on specific ...
