Refractory metals also tend to have slow diffusion rates so they are often added for creep resistance in alloys. Diffusion rates are dependant on chemistry so there is not a simple rule for which element is the slowest diffuser–but rhenium is famously slow in nickel-based superalloys and gives rise to the "rhenium effect" of excellent
