TL;DR: In this paper, the authors evaluated the use of activated flux TIG (ATIG) welding for the austenitic stainless steels with fluxes of only one major component and found that even the very simple flux that was used can greatly increase the penetration of the weld bead.

TL;DR: In this article, four different coatings were deposited onto an AISI 1020 steel substrate: (i) WC-12%Co, (ii) as-sprayed (AS) 50%(WC 12%Co)+50%(NiCr), (iii) post-melted (PM) and (iv) a duplex system comprising a WC 12% Co top layer and a NiCrAl interlayer.

TL;DR: In this article, the authors analyzed low-cycle fatigue life under strain control (ea-Nf curve) of NiTi wires in bending-rotation tests, with strain amplitudes from 0.6% to 12% on stable austenite, superelastic, and stable martensite wires.

TL;DR: In this paper, the indentation toughness of high velocity oxy-fuel thermally sprayed WC-12%Co coatings has been evaluated using a standard metallographic procedure, and two crack regimes were found to occur in such coatings, depending on their indentation load.

TL;DR: In this paper, a numerical model was developed to calculate temperature distribution along the electrode during welding, and the results from this procedure were compared to data from the literature and used with high speed video image recording of the arc region to explain the anomaly in the melting rate curve that is observed when welding is performed with constant current power supplies.
