Cold welding of Ag nanowires by large plastic deformation

Scripta Materialia, 2016
Abstract The conventional cold welding concept was extended to nanoscale, in which silver nanowires were welded together by large plastic deformation. A nanoindenter was employed as a cold welding tool to visualize and conduct welding. The MD simulation shows that unlike single crystal nanowire, sufficient plastic deformation is key to realize ...

Effect of cold rolling on plastic deformation and microstructure of bearing ring

Materials Science and Technology, 2017
Bearing ring blanks of the high-speed rail bearings, machine tool spindle bearings and wind power bearings have been manufactured through the ring rolling technology. Yet, the microstructure evolution of bearing ring in cold ring rolling remains unclear. In this work, the plastic strain distribution of the rolled ring is first simulated.

Deformation Behavior of Finely-Lamellar Pearlite During Multiple Cold Plastic Deformation of Eutectoid Steel

Metal Science and Heat Treatment, 2019
Deformation behavior of finely-lamellar pearlite in steel with 0.78% C during multiple cold plastic deformation by drawing is considered. It is revealed that during deformation apart from ferrite platelet thinning with an increase in overall reduction cementite phase behavior starts to play a more important role. The change in distance between pearlite
