dc.description.abstractFriction Stir Welding method is a welding method which utilize friction between rotate cutting tool which pressed to material, so it will generate local heat and make material soften and will be integrated or merged. The aim of this study is to understand the effect of rotational speed (808 rpm, 1087 rpm, 1570 rpm) to hardness and microstructure of composite AlSiTiB-7.5%SiC welding by using a tool which have conical pin shaped, with welding speed is 0.02 mm/s. The results showed a significant increase in hardness value in the stir zone (nugget) region and TMAZ-HAZ interface region to hardness value of base metal. Rotational speed using 1087 rpm has highest average value of hardness in the area of the stir zone (nugget) with value 126.4 HV, while at 808 rpm the hardness value is 118.1 HV and at 1570 rpm is 74.6 HV. The microstructure result at 1087 rpm rotational speed showed no defects or wormhole occured if compare with 808 rpm and 1570 rpm rotational speed which has defect or wormhole.en_US
