Hot Deformation Processing in Hybrid Metal Additive Manufacturing using Gleeble 563 +Simu-Mat 1.0

Presented by: Clodualdo Aranas Jr., PhD, PEng Associate Professor, Mechanical Engineering Department, University of New Brunswick Abstract: This webinar demonstrates the application of thermomechanical processing and material constitutive modeling to assess the mechanical performance of the additively manufactured M789-N709 hybrid alloy system for tool and die application. The hybrid material was fabricated by depositing M789 steel on wrought N709 steel by means of the laser powder bed fusion (LPBF) technique. Extensive heat treatment and microstructural analysis were carried out to analyze the compatibility of the alloy combination. To model the high-temperature response of the material, hot compression tests were performed on both M789 and N709 steels using the Gleeble 563. Then, phenomenological-, physical-, and artificial neural network-based constitutive material models were then established utilizing Simu-Mat 1.0. The material models established in this work can now be employed to estimate the response of the hybrid alloy system at elevated temperatures.
