The intellectual challenge addressed in this proposal involves the establishment of a sciencebased protocol for optimizing processing and heat treatment routes to produce a new class of MEMS materials (electrodeposited Ni-base superalloys) that will dramatically improve the functionality and expand the temperature capability of electrodeposited LIGA materials. A collaborative international research team is prepared to undertake this task. Overarching scientific issues to be addressed by this team include: (i) control and optimization of electrodeposition parameters to uniformly entrain Al nano-particles in ED Ni micro-components, (ii) development of heat treat schedules required to transform the as-deposited green composites into γ-γ’ superalloy microstructures, and (iii) characterization of the resultant microstructures and attendant mechanical properties. Close interaction of the research groups will allow for optimization of the process flow and result in the creation of novel high temperature LIGA ED Ni-base superalloys for MEMS applications. Close collaboration between the two institutions will be required to fulfill the scientific mission of the proposal, and integrated exchanges of graduate students and senior researcher scientists will create the vehicle for this collaboration and provide a unique educational experience for the students.
