Today, the usage area of metal matrix and ceramic reinforced composites is increasing and researches in this field are increasing. However, majority of the studies conducted are constituted of studies on investigation of mechanical features of composites. One of the reasons why composite materials are preferred is because these materials have improved thermal property. With this experimental study, it is aimed to contribute to the literature in the area of investigating features of thermal properties. In this study, composite materials were produced at 500 °C, 550 °C and 600 °C sintering temperatures by adding 4%, 8% and 16% B₄C to Al 1070 quality aluminium by powder metallurgy technique. Firstly, the microstructures of the composites were investigated. Then, experiments were conducted to determine the specific heat of composite materials at different ambient temperatures together with thermal conductivity measurements. With the data obtained from the experiments, finite-element modelling was done and the thermal properties of the composite structure were optimised. In the microstructure studies, it was determined that with the increase in the B₄C reinforcement ratio, the reinforcement agglomeration and porosity in the composite structure were found. As a result of the thermal experiments, it was observed that the thermal conductivity values of the composites were inversely proportional to the amount of B₄C reinforcement and as the reinforcement ratio increased, the thermal conductivity values decreased. Besides, it was determined that the sintering temperature has an effect on the thermal conductivity value and that it increases the thermal conductivity of the composites with increasing sintering temperature. The highest heat conduction coefficient was obtained at 4% B₄C reinforcement ratio and 600 °C sintering temperature. It was observed that the finite-element models prepared to determine the heat conduction coefficient effectively were consistent with the experimental results.

如今，金属基和陶瓷增强复合材料的使用范围不断扩大，该领域的研究也在不断增加。然而，大多数进行的研究都是对复合材料力学特性的研究。优选复合材料的原因之一是因为这些材料具有改进的热性能。通过这项实验研究，旨在为研究热特性特征领域的文献做出贡献。在本研究中，通过添加 4%、8% 和 16% B ₄在 500 °C、550 °C 和 600 °C 烧结温度下生产复合材料C 至 Al 1070 优质铝，采用粉末冶金技术。首先，研究了复合材料的微观结构。然后，进行实验以确定复合材料在不同环境温度下的比热以及热导率测量。利用从实验中获得的数据，进行了有限元建模，并对复合结构的热性能进行了优化。在微观结构研究中，确定随着B ₄ C 增强比的增加，在复合结构中发现增强体团聚和孔隙率。作为热实验的结果，观察到复合材料的热导率值与 B ₄的量成反比C 增强，随着增强比的增加，热导率值下降。此外，已确定烧结温度对热导率值有影响，并且随着烧结温度的升高，复合材料的热导率增加。在 4% B ₄ C 增强比和 600 °C 烧结温度下获得最高的热传导系数。观察到，为有效确定热传导系数而准备的有限元模型与实验结果一致。
