Electrical resistivity measurements have been performed on a series of mono- and polycrystalline U(Pt1-xPdx)3 compounds (x ⩽ 0.15) in the temperature range 1.4-300 K. On alloying with Pd the spin-fluctuation-like resistivity of pure UPt3 transforms into a more complex curve for x = 0.02 and x = 0.05 revealing a transition at 3.3 K and 5.6 K, respectively. At higher Pd concentrations (x = 0.10,0.15) the resistivity curves change to a Kondo-type of behaviour. In the same concentration range a second phase appears in the X-ray patterns.
