| Popis: | The paper deals with the fabrication of lap joints of titanium ОТ4-1 alloy and aluminum AlMg5 alloy sheets by means of friction stir welding (FSW). The X-ray diffraction and energy dispersive X-ray analyses show that in the FSW zone, the formation of four intermetallic compounds occurs, viz. TiAl3, TiAl, TiAl2 and Ti3Al. It is found that the lower plunge depth into the substrate and the increased FSW rate do not prevent the intermetallics formation. The microhardness distribution in the FSW joint is non-uniform and its maximum value reaches 4 GPa. |
