“…As can be seen from Fig. 6, the electrical resistivity values are between 8.85 -45.86 · 10 -8 X m. These are close to the resistivity values 7.53 -33.2 · 10 -8 X m and 7.58 -29.4 · 10 -8 X m obtained by Ikeda et al [35] and Çadırlı [36], respectively. the evaluation of the alloy design, so characterization of these properties is needed.…”

Influences of high temperature on the microstructural, electrical and mechanical properties of Ni-23 wt.% Al alloyThe microstructural, electrical and mechanical characteristics of conventionally and rapidly solidified Ni-23 wt.% Al alloys after heat treatments were investigated. The microstructures of Ni-23Al alloys were examined by means of scanning electron microscopy and the phase composition was identified using X-ray diffraction analysis. The phase transitions during the solidification process were investigated using differential thermal analysis under an Ar atmosphere. X-ray diffraction analysis indicated that the Ni-23Al samples showed an intermetallic c'-Ni 3 Al phase, and we observed the intermetallic c'-Ni 3 Al phase together with the b-NiAl phase after heat treatment at 700 -900 8C for 24 h. We performed electrical resistivity measurements by using the four-point probe technique in the temperature range 100 -900 8C. The resistivity of Ni-23 wt.% Al samples increases linearly with temperature. Vickers microindentation tests were carried out on the heat-treated samples with loads ranging from 392.26 mN to 1 174.86 mN at room temperature. We found that the microhardness and effective elastic modulus values increased with increasing temperature and these values showed peak load dependence. The tensile and compressive stress values of the Ni-Al alloys also decreased with increasing temperature. E. Karaköse, M.

“…Rapid solidification (RS) techniques provide significant microstructural and constitutional changes [10,12,13] in many alloys. Some of the unique properties achieved by RS techniques consist of solid solubility extension, grain size refinement, formation of metastable phases and in some cases formation of amorphous and quasicrystalline phases, with many of these effects improving the mechanical properties of alloys, especially lightweight metals [10,14] .…”
