Investigation of the thermal effect of thermal effici-ency in Fe-%27Ni-%4Mn-%1Zn alloy

In this study, phase transformations of Fe- 27% Ni- 4% Mn- 1% Zn alloy with ther-mal effect were investigated. Some physical properties of the martensitic transforma-tion as a result of the heat transfer effect on the alloy and the martensitic phase trans-formation formed in the alloy with the effect of heat treatment on the alloy, were investigated by scanning electron microscope (SEM), Vibrating sample magnetometer (VSM) techniques. From the scanning electron microscope (SEM) investigations, Fe-%27 Ni-%4 Mn-%1 Zn alloy was observed in the martensitic conversion. Fe-%27 Ni-%4 Mn-%1 Zn alloy was formed by the thermal effect of martensite structure Z lath martensite termal morphology was observed to show the structure. Magnetization-Applied Area (M-H) curve showed a ferromagnetic behavior. The saturation magnetization value of the sample was about 21 emug-1. In addition, for example the compelling field value ob-tained from the M-H curve was obtained as about 36 Oe
