IMPROVEMENT IN MICROSTRUCTURE PERFORMANCE OF THE NiCrBSi REINFORCED COATING ON TA15 TITANIUM ALLOY

PENG, LI - In: Surface Review and Letters (SRL) 19 (2012) 05, pp. 1250047-1

This work is based on the dry sliding wear of NiCrBSi reinforced coating deposited on TA15 titanium alloy using the laser cladding technique, the parameters of which were such as to provide almost crack-free coatings with minimum dilution and very low porosity. SEM results indicated that a laser...

A STUDY ON MICROSTRUCTURE CHARACTERISTICS OF IN SITU FORMED TiC REINFORCED COMPOSITE COATINGS

LIU, PENG; GUO, WEI; LUO, HUI - In: Surface Review and Letters (SRL) 19 (2012) 02, pp. 1250016-1

In situ synthesized TiC reinforced composite coating was fabricated by laser cladding of Al-Ni-Cr-C powders on titanium alloys, which can greatly improve the surface performance of the substrate. In this study, the Al-Ni-Cr-C laser-cladded composite coatings have been researched by means of...

Statistical mechanics of nucleation in solids: a kinetics driven morphological transition

Sengupta, Surajit; Rao, Madan - In: Physica A: Statistical Mechanics and its Applications 318 (2003) 1, pp. 251-261

We examine in detail, through extensive molecular dynamics simulations, the process of nucleation of a triangular phase in a model two-dimensional square crystal consisting of particles interacting via a pair and three-body potentials. We find that at high temperatures, the critical nucleus of...

Atomistic simulation of matter under stress: crossover from hard to soft materials

Romano, Antonino; Li, Ju; Yip, Sidney - In: Physica A: Statistical Mechanics and its Applications 304 (2002) 1, pp. 11-22

Atomistic simulation can give insights to the mechanical behavior of stressed crystalline hard materials. Theoretical strength, defined in the long wavelength limit through elastic stability criteria, or more generally in terms of soft vibrational modes in the deformed lattice, can be studied by...
