3.1. Chemical composition of Al6061Al 2 O 3 cast composites Table shows the chemical composition of Al Al O composite analysed by Optical Emission Spectroscopy OES . The composition design was different from OES result. The Mg content should be wt or less but the OES measured was wt, while Ti closed to material balance which was design before casting but for Sr the OES measured was strayed away from designed alloy. t is assumed that deviation can be caused by the over reading of the instrument to measure the Mg and Sr content inside of the material.

Effect of Ti on mechanical properties of Al6061 Al 2 O 3 composite The mechanical properties of Al Al O such as tensile strength, elongation and hardness are shown in Figure . They are seen that composites with . wt‐ Ti addtion has the highest both tensile strength and elongation Fig. a,b , eventhough the addition of . wt‐ Ti has the highest strength with the value of MPa. The hardness of composites is RB which is optimum obtained at . wt‐ Ti addition. There are many factors can cause the highest of mechanical properties, some of them might be the distribution of the Al O p , the porosity formed in the composites, the wettability of the matrix, and the formation of intermetallic compounds. The addition of Ti in the as cast composite is to be known for the effect of grain refinement. t brings the effect of refinement by heterogeneously nucleating the TiAl and TiB and restricting the growth of the grains Kashyap and Chandrasekar, . eterogeneous nucleation involves peritectic reaction. The result of peritectic reaction, TiAl and TiB , will become nucleates and continuously become sites for nucleus of Al. This condition subsequently will give more nucleating process rather than growing process of the Al. Thus, the process of refinement consists of two mechanisms, first is serve nucleating sites for Al nuclei and restrict the growth of Al. Boron is also counted as the refinement agent because it reacts along with Ti to form TiB which are insoluble in Al. Even so, the superior effect of refinement is still generated by the formation of TiAl intermetallic compound because it is believed that the lattice disregistry of TiAl is smaller than TiB Sigworth and Johnsson, . The refinement will result to the finer grain of matrix Al generates the remarkable mechanical properties. Besides, the addition of Al‐ Sr will also result good modification to the formation of the second phases. n this study, the Ti addition up to . wt and constant number of . wt Sr gives the highest UTS among other samples. t is firstly concluded that the refinement process takes place in the as cast composites.Parts
