Microstructure evolution during warm deformation of low carbon steel with dispersed cementite
(2007-12-01)
The microstructure evolution and mechanical behavior during large strain of a 0.16%C-Mn steel has been investigated by warm torsion tests. These experiments were carried out at 685°C at equivalent strain rate of 0.1 s . ...

Rationalizing the effect of accelerated carbonation and accelerated ageing on transition zone of cellulose fibers in cement based composites
(2015-01-01)
The objective of the present work is to show the effect of accelerated carbonation on the transition zone of cellulose fibers in cement based composites. Accelerated carbonation increased the content of calcium carbonate ...
Ion Beam Optimized Mechanical Characteristics of Glassy Polymeric Carbon for Medical Applications
(2003-08-26)
Glassy Polymeric Carbon (GPC) has medical applications owing to its inertness and biocompatible characteristics. Commercial GPC prosthetics include mitral, aortic and hydrocephalic valves. Surface treatment of GPC increases ...
