Abstract

The aim of this research was the production of in-situ Al-Al3Ti composite on the surface of Al1050 alloy, using friction stir processing with reactive mechanically alloyed Al-Ti powder. Al-Al3Ti was fabricated with different rotational speeds and FSP passes. the primary Al-Ti powder was mechanically alloyed for different durations and suitable time for achieve a fine lamellar and uniform structure was determined. microstructral evaluations were implemented by optical microscopy (OM) and scanning electron microscopy (SEM). X-ray diffractometery (XRD) was used for phase identification and differential scanning calorimertry (DSC) was used to study the thermal behavior of powder during heating. Vickers micro hardness test and tensile test were used to evaluate mechanical properties of the base metal and FSPed samples. using mechanically alloyed Al-Ti particle led to the enhancement of hardness by 2. 5 times, tensile strength by 3. 4 times. meanwhile increasing the number of passes to 4, improved the reaction of Al3Ti formation in Al matrix. Improved the distribution of in-situ particles in the matrix caused better mechanical properties. Evaluation of the fracture surfaces indicated ductile fracture for all specimens.
