Modeling the micro-indentation of metal matrix composites
(Elsevier Science Sa, 2007-08)
A finite element model is developed to quantify the effect of the depth and diameter of the reinforcement in the hardness number of metal matrix composite. The model includes a spherical indenter pressed against a metal ...
Influence of silicon on wear behaviour of "silal" cast irons
(Universidad Nacional de Colombia Sede Medellín, 2014-12-16)
The tribological and mechanical properties of various cast irons with different contents of carbon and silicon are studied. The Brinell hardness or every cast iron was measured and their wear resistance was calculated ...
Modelado de la microdureza de materiales compuestos
(Asociación Física Argentina, 2006-12)
La microdureza de los materiales compuestos de matriz metálica está afectada por la presencia de partículas de refuerzo en la subsuperficie del material. La microdureza está directamente relacionada a las propiedades de ...
