Abstract
Titanium stiffness has been reduced producing porous specimens by means of microsphere sintering. Mathematical models are not suitable to model the sintering process of the present study, as they are based in parameters such as density, shrinkage or porosity, which vary very little in the porous samples developed. The Zero-Order Reaction Rate Model (ZORR) and Transition State Theory (TST) were therefore used as an alternative method to model the sintering process and estimate bending strength of porous Ti6Al4V obtained by microsphere sintering. Although the model parameters have been obtained only for the microsphere sizes analysed, the strength of intermediate sizes could be easily estimated following this model.
