Additive manufacturing of Ti-6Al-4 V alloy via laser powder-bed fusion leads to non-equilibrium α′ martensitic microstructures, with high strength but poor ductility and toughness. These properties may be modified by heat treatments, whereby the phase decomposes into equilibrium α+β structures, while possibly conserving microstructural features length scales lath structure. Here, we combine experimental computational methods explore kinetics martensite decomposition. Experiments rely on...
Abstract Bioresorbable Mg-based alloys with low density, elastic modulus, and excellent biocompatibility are outstanding candidates for temporary orthopedic implants. Coincidentally, metal additive manufacturing (AM) is disrupting the biomedical sector by providing fast access to patient-customized Due high cooling rates associated fusion-based AM techniques, they often described as rapid solidification processes. However, conclusive observations of in AM—attested drastic microstructural...
The development of the ausferritic transformation a ductile iron was analysed using novel cellular automaton-finite difference model, which considers geometrical details microstructure, nucleation new phase at graphite nodule surface, contact between growing phases, and carbon diffusion in austenite. role nucleation, austenite enrichment, phases different stages growth kinetics studied. Moreover, parametric study performed to investigate influences size, austenitizing austempering...
This paper presents numerical results of stress concentration factors for plates perforated by corrosion. Evidence from 25 with corrosion perforation considered show that typical shapes may be characterized as a deviation an ellipse or circle. In order to model perforations created this type corrosion, holes non-circular boundaries have been in the form cosine shape and variations it. Two load cases are investigated: uniaxial shear fields elastic plane problem. The influence amplitude...
Additive manufacturing of Ti-6Al-4V alloy via laser powder-bed fusion leads to non-equilibrium $\alpha'$ martensitic microstructures, with high strength but poor ductility and toughness. These properties may be modified by heat treatments, whereby the phase decomposes into equilibrium $\alpha+\beta$ structures, while possibly conserving microstructural features length scales lath structure. Here, we combine experimental computational methods explore kinetics martensite decomposition....

The influence of alloy element distributions on austempered ductile iron microstructure and austempering treatment was analysed by a cellular automaton model that considers the ausferritic martensitic transformations. initial is modelled as spherical graphite nodules inserted in an austenitic matrix, which elements are distributed uniform or non-uniform way. study performed for different chemical compositions nodule sizes. Delays development transformation produced increment size presence...
RESUMEN El manejo adecuado de estructuras porosas, en aplicaciones biomédicas, tiene una relevante importancia evitar la reabsorción y permitir el correcto crecimiento óseo. Estas conducen a nucleación del hueso su interior, consiguiendo óptima unión entre implante este. En consecuencia, este trabajo investiga un proceso fabricación porosas titanio obtenidas mediante técnica pulvimetalúrgica basada tanto método gel-casting como sinterización. técnicas nos permiten controlar cantidad, tamaño,...
