Özet
Bu çalışmada, Fe-%25Ni-%3V alaşımında deformasyon etkisi ile oluşan Martensitik dönüşümün mikro yapısı ve termal özellikleri araştırıldı. Zor etkili martensitelerin mikro yapıları Taramalı Elektron Mikroskobu (SEM) ile incelendi ve bunların termal özellikleri ise Diferansiyel Tarama Kalorimetresi (DSC) ölçümleri sonucunda belirlendi. Farklı oranlarda uygulanan plastik deformasyon miktarı arttırıldığında zor etkili martensite miktarının arttığı mikro yapı incelenmesinde gözlendi. Ayrıca plastik deformasyon miktarının Ms Martensitik dönüşüm sıcaklıklarını arttırdığı DSC ölçümleri ile ortaya kondu.
In this study, the micro structure and the thermal properties of martensite transformation induced with deformation effect were investigated in Fe-25%Ni-3%V alloy. Micro structures of deformation induced martensite were observed with Scanning Electron Microscope (SEM) and thermal properties of these were determined by result of Differential Scanning Calorimeter (DSC) measurements. It was observed that the amount of martensite was increased in the investigation of the microstructure when the amount of practiced plastic deformation was increased different rates. In addition, it was exposed that the amount of plastic deformation increased Ms Martensitic transformation temperatures with DSC measurements.
