FeMnSiCrNi shape memory alloy
bending creep
creep rate
multifractal model - Opis:
- FeMnSiCrNi alloys represent a promising class of FeMnSi-based shape memory alloys (SMAs) characterized by excellent characteristics of formability and corrosion resistance. The present paper is focused on a 68Fe-18Mn-3Si-7Cr-4Ni (mass. %) SMA, produced by powder metallurgy routine, which was tested to creep, using a dual cantilever specimen holder, and analyzed by means of the dedicated software of a dynamic mechanical analyzer. The specimens were tested at five temperatures by applying, at each of them, four bending force values, during 2000 s. The variation of bending creep deflection with time, temperature and force was discussed both from the point of instant value and 1000 s-value. These results enabled plotting a space diagram of stabilized creep rate variation with both applied force and test temperature. In such context, a theoretical model in a multifractal paradigm of motion was built, considering that FeMnSiCrNi shape memory alloy can be assimilated, both structurally and functionally, with a multifractal object. Finally, this model was validated by means of experimental data.
