Effect of Ni and Si additions on AL-Cr-Mn eutectic alloy on microstructure, mechanical and thermoelectrical properties

This is effective, Al-0.3% Cr(wt)-2.0% Mn-0.5% Si(wt), Al-0.3% Cr(wt)-2.0% Mn-0.5% Ni(wt) and Al-0.3% Cr(wt)-2.0% Mn-0.5% Si-0.5% Ni(wt) alloys, high purity aluminum, chromium, manganese, silicon and nickel elements It is produced by directional solidification in the casting furnace using The structure ratios of these alloy micros were obtained using a FEI-Quanta FEG 250 model Scanning Electron Microscope (SEM). Additionally, Energy Dispersive Spectrometry (EDS) and X-Ray Diffraction (XRD) peaks were measured and an image map was made. Tensile strength tests were determined using the Future Tech FM700 model Vickers production testing device. A load of 100 grams is loaded over a period of 10 seconds. Tensile strength tests were performed on the samples with Shimadzu Universal Tester in accordance with ASTM E4 standard. Tests were performed on cylindrical specimens spanning 4 mm and length 60 mm with Shimadzu Universal Tester at 1 mm/min strain modulus of the medium. Additionally, the effect of the heat treatment process on the thermophysical properties of the alloy was investigated by the Differential Thermal Analysis (DTA) method. This possibility is caused by changes in melting temperature, fusion enthalpy and heat capacity, which are important in changing the kinetics of the liquid-additive phase transition.
