Abstract
Effects of aging and solution annealing treatment on the
super elastic respond of the cold-worked Ni50.9%-Ti thin
wire was studied in nano-scale utilizing instrumented
nanoindentation. The nanoindentation results were coupled
with the tensile test results to provide better insight
to the governing deformation mechanisms. The first
applied heat treatment heat treatment the cold-worked
wire tensile test and nanoindentation results showed
better super elastic behavior for the wire subjected to
second treatment. Indentation displacement bursts were
observed in loading course after both treatments.
However, slope changes in unloading course of indents
were recorded after second heat treatment which might be
due to reverse phase transformation. Surface asperities
on the post-indented surface after first treatment were
observed far away from indentation stress field by atomic
force microscopy.
