The work is focused on the microstructural and mechanical characterization of linear friction welded rolled homogenized armor (RHA) steel subjected to different load conditions. RHA steel is extensively used for ballistic impact resistance of armored vehicles. To study the effect, RHA steels were subjected to different set of loads namely 200 KN and 100 KN. Microstructural analysis was conducted using electron backscattered diffraction technique. The samples were subjected to tensile testing in order to examine the strength of the joint. It was found that the average grain size at the center of the weld reduced with the reduction in load. The fractography results showed that the fracture occurred with ductile fracture. Interestingly, none of the samples broke from the weld joint which shows the strength in the weld is higher than that of the sample.
