Influence of electrodeposited Cu-Ni layer on interfacial reaction and mechanical properties of laser welded-brazed Mg/Ti lap joints
(
Elsevier
, 2019 , Article)
A fiber laser welding-brazing procedure has been developed for joining AZ31B magnesium alloy to Cu-Ni coated Ti-6Al-4V titanium sheet using AZ92D filler wire. The effect of the interlayer arrangements (AZ31B/Ni-Cu/Ti-6Al-4V ...
Soffit and U-Wrap fabric-reinforced cementitious matrix strengthening for reinforced concrete beams
(
American Concrete Institute
, 2019 , Article)
The structural performance of reinforced concrete (RC) beams strengthened with fabric-reinforced cementitious matrix (FRCM) was investigated. Fourteen unstrengthened and strengthened beams were tested in flexure under ...
