dc.description.abstractThis study aimed to theoretically optimize the Mg-Dia interface with components of different types and thicknesses to increase the thermal conductivity of diamond-doped magnesium matrix composites. Acoustic mismatch (AMM), diffusion mismatch model (DMM) and differential effective medium (DEM) models were used for TC calculations of the designed composites. According to the results, TiC, SiC, ZrC, and B4C carbides are the components that can increase the TC value up to 529 W/mK; however, most of (t)hem, except SiC, negatively affected the TC value with the increase in thickness. B and Cr elements also provided higher TC values compared to other elements. Except for the Cr-CrC3C2 conversion, all other carbide conversions had a positive effect on TC. MgO, Al2O3 and ZrO oxides alone or together with MgO increased the TC value up to 525 W/mK. Apart from this, MgO had a negative effect on all components except B or B4C. As a result, Mg-MgO-B-Dia was observed as the component providing the most stable TC value even if the thickness increased. This is thought to be due to less scattering during heat transfer between components with close Debye temperatures. It has also been understood that these results can deviate 29% from the experimental one even with the best method.en_US
