Use of pure vanadium and niobium/copper inserts for laser welding of titanium to stainless steel

open access: yesJournal of Advanced Joining Processes, 2020
Niobium and vanadium have high metallurgical compatibility with titanium and therefore can be used as inserts to avoid the accumulation of brittle intermetallic phases such as Fe2Ti during the fusion welding of titanium alloys with steels. In the present

Effect of hydrogen implantation at high temperature on the microstructural evolution of vanadium alloys

open access: yes工程科学学报, 2016
The microstructure evolution of V-4Cr,V-4Ti and V-4Cr-4Ti alloys was studied before and after hydrogen implantation at 500℃. Before hydrogen implantation the matrix of V-4Cr alloy is clean,while parallel and vertical needle-like precipitates exist in the

LEAD: Literature Enhanced Ab Initio Discovery of Nitride Dusting Layers for Enhanced Tunnel Magnetoresistance and Lower Resistance Magnetic Tunnel Junctions

open access: yesAdvanced Materials, EarlyView.
Magnetic tunnel junctions (MTJs) using MgO tunnel barriers face challenges of high resistance‐area product and low tunnel magnetoresistance (TMR). To discover alternative materials, Literature Enhanced Ab initio Discovery (LEAD) is developed. The LEAD‐predicted materials are theoretically evaluated, showing that MTJs with dusting of ScN or TiN on ...

A Colloidal Quantum Dot Thermistor and Bolometer

open access: yesAdvanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...
