Simultaneous Measurement of Continuum Strain Field and Intermittent Martensite Band Nucleation in Single Crystal Ni-Mn-Ga Foils
Abstract (englisch):
A method is presented for the simultaneous measurement of a macroscopic continuum strain field and microscopic intermittent martensite band nucleation behavior arising in single-crystal Ni-Mn-Ga foils under deformation. The continuum strain field was measured using Digital Image Correlation. The intermittent martensite band nucleation was measured using Stress Drop Analysis in a stress-strain curve. Comparison of the results reveals a phenomenological correlation. This method is extremely useful for investigation of deformation mechanisms in single-crystal shape memory alloys.
