... of nanocomposite dispersion and morphology on the dynamic behavior, another nanocomposite was prepared by melt mixing of polypropylene and a modified montmorillonite (dellite) (PP dellite). The dynamic property results for PP-nanocor show an increase of both Young’s modulus and yield stress with the increasing...

... spectroscopy, microindentation, and nanomechanical tester. The dendrite structure exists at the fusion zone. The partially melted zone is found near the fusion line. The tensile tests show that the welded alloy exhibits lower strength and ductility than the base alloy, and failure occurs at the partially...

...Stuart Barnes; Michael J. Nash; Y. K. Kwok A 1200 W diode laser was used to modify the surface properties of a fully-sintered ferrous PM material. Two modifications were investigated; transformation hardening of selected areas and sealing of surface porosity by re-melting. The diode laser was used...
