| Abstract Scope |
Directed energy deposition additive manufacturing (AM) techniques allow for the fabrication of functionally graded parts. A powder fed laser AM system was used to produce a compositionally graded Ti-Cr sample with a defined wedge geometry. This sample was then resistively heated using a thermomechanical simulator Gleeble to apply a two-step heat treatment process, resulting in a sample with orthogonal compositional and thermal gradients, and spatially dependent thermal histories. A three-dimensional coupled structural-thermal-electrical finite element model for the heat treatment was developed and validated to predict/monitor thermal histories across the sample. Combined analysis of the model, microstructure and mechanical properties will be discussed to reveal correlations between processing, properties, and microstructure. |
