“…A significant reduction in the HV microhardness values could be expected with the increase in the load related to the stress induction of martensite. Our results corroborate with that one reported by Mahtab et al [31]. The results show a linear correlation between microhardness and stress induction stress, where an increase in microhardness with increasing induction stress in NiTi alloys is presented.…”

The influence of simultaneous doping of Ti and B on the thermomechanical, structural, and magnetic properties of CuAlMn Heusler alloys was evaluated in this study. The samples were prepared via induction casting, and they were characterized by X-ray diffraction, differential thermal analysis, optical microscopy, scanning electron microscopy, mechanical microhardness tests, and magnetometry. The alloys presented the austenite phase with L2 1 ? DO 3 structures. It was found that the doping of TiB reduced the average grain size and increased the amount of second-phase precipitates, which was attributed to the low Ti solubility in the austenitic matrix. A reduction in the values of Curie temperature, melting temperature, melting enthalpy, and HV microhardness was observed with the doping of TiB to the CuAlMn ternary system. It was also verified that the simultaneous doping of Ti and B changed the magnetic behavior of the CuAlMn system from paramagnetic (with weak ferromagnetic contribution) to ferromagnetic order. Our results bring to light a new alternative to doping CuAlMn alloy, and improve the structural and magnetic properties, interesting parameters for technological applications.
