Searching for evidence of ``cold'' nuclear fusion in deuterium-loaded Ti and Pd foils with plastic track detectors, we detected the emission of \ensuremathα particles from trace-heavy-element decay, but found no evidence of dd fusion. Cycling TiD2 and PdD>0.4, in high-pressure D2 cells between 1 and 15 bars and 77 and 300 K, gave an upper bound of 0.7 cm^\mathrm\ensuremath-3 s^\mathrm\ensuremath-1 for the mean rate of dd\ensuremath→3He+n fusion. For electrolytically deuterated PdD0.8 our upper bound is 0.0018 cm^\mathrm\ensuremath-3 s^\mathrm\ensuremath-1 for the mean rate of dd\ensuremath→p+t. This is \ensuremath∼1.5\ifmmode×\else\texttimes\fi106 and 180 times lower than ``cold''-fusion rates reported by Fleischmann, Pons, and Hawkins and Jones et al., respectively.
