A METHOD FOR MAKING STABILIZED PLUTONIUM ALLOYS HAVING A MIXTURE OF ALLOTROPES CONSISTING ESSENTIALLY OF ALPHA AND DELTA AND THEREBY OBTAINING IN SUCH ALLOYS HARDNESS, POSITIVE COEFFICIENT OF EXPANSION, AND DENSITY WHICH ARE INTERMEDIATE THOSE OF UNDILUTED DELTA PHASE AND UNDILUTED ALPHA PHASE PLUTONIUM. CHARACTERIZED BY COMPRESSING SAID ALLOY TO AT LEAST A PRESSURE WHICH PRODUCES RAPID INCREASE IN DENSITY WITH A NEGLIGIBLE INCREASE IN PRESSURE, SAID ALLOYS COMPRISING BINARY ALLOYS OF PLUTONIUM CON-
