The effect on the microstructure and mechanical properties of the composites produced by adding different ratios of B4C-TiB to the alumium 8062 matrix alloy

In this study, composite material was produced by adding different ratios of B4C powder and Al-Ti-B alloy to 6082 aluminum alloy. A total of 6 different composite samples were produced as 6082 Al with aluminum matrix, 6082 Al+Al-Ti-B, 6082 Al+B4C in 2 different ratios, 6082 Al+Al-Ti-B+B4C in 2 different ratios. Spectro analysis, optical examination, micro and macro hardness and SEM analysis were performed on these samples. In the spectro analysis obtained, mainly Al, Ti, B, C elements were observed. The macro and micro hardness values of the matrix material Aluminum and other Al composites obtained were compared and significant increases in hardness values were observed in the composite materials obtained compared to Aluminum. In the optical and SEM examinations, it was observed that Al-Ti-B and B4C particles were heterogeneously dispersed in aluminum. The experimental results of the successfully obtained composite materials are discussed and evaluated with the literature.
