Description
We submitted a proposal to CINT to conduct research on “Microstructural Investigation of High
Temperature and Strength Shape Memory Alloys” and it was accepted.
We plan to conduct in-situ TEM nano-indentation experiments on homogenized (precipitation free)
and 500°C-3h aged (precipitation size of 20 nm) NiTiHfPd single crystals along [111] and [100]
orientations to determine characteristics of the stress-induced martensite reorientation of two
samples with different martensite morphologies.
We would utilize the CINT Focused Ion Beam (FIB) to fabricate samples and in-situ TEM nanoindentation
capabilities at CINT-SNL in collaboration with K. L. Jungjohann (CINT-SNL).
O.Anderoglu (LANL) is also a trained user of both the TEM and FIB, and will help H. Tobe in an
effort to minimize ramp-up time to conduct meaningful experiments.
This study is highly important in order to gain the fundamental knowledge on the effects of
precipitates and orientation on the martensite morphology and deformation mechanisms; and to
control the shape memory and material properties of NiTiHfPd alloys by tailoring their
microstructure. The findings will be compared with nano and micro-indentation and compression
tests done at bulk samples. The research findings will be published in journals and presented in
conferences to promote the research conducted at University of Kentucky and establish international
collaborations. Furthermore, we plan on submitting new proposals to NSF and DOE on high
strength shape memory alloys to establish their processing-microstructure-property relationships.
