This is the final progress report of activities at Texas Engineering Experiment Station TEESTexas AM University TAMU on work related to the AFOSR Defense University Research Instrumentation Program DURIP Project titled, Acquisition of Mechanically Assisted Spark Plasma Sintering System for Advanced Research and Education on Functionally Graded Hybrid Materials . The effective beginning date of Contract No. FA9550-10-1-0398 was September 15, 2010. The project was aimed at developing facilities for pressure-assisted fabrication of hybrid materials by spark plasma sintering SPS of metallic and ceramic powders to support a wide range of research AFOSR activities that cannot be easily achieved using existing facilities at Texas AM University, including MURI project entitled Synthesis, Characterization, and Prognostic Modeling of Functionally Graded Hybrid Composites for Extreme Environments . Several different components were acquiring, installed and tested the proposed systems have been successfully installed at Texas AM University. Different MAX phases, as well as their composites with the Shape Memory Alloys SMA have been fabricated and they demonstrated unprecedented mechanical damping due to residual stresses in MAX phases induced by the shape memory effect. In addition, the SPS was used to join ceramics MAX phases to the SMA NiTi and study the kinetics of the interfacial reactions. The acquired SPS fabrication system is one of the most powerful in the academia and will allows us to systematically fabricate and study structural, physical and mechanical properties of these hybrid materials.
