P/M AI-Cr-Ce and AI-Cr-Mm (misch metal) base alloys were prepared by extruding their alloy powders with particle sizes below 25μm and 75μm, respectively. The ultimate tensile strength (σUTS), plastic elongation (εp) and Vickers hardness (Hv) of the P/M Al-Cr-R (R=Ce, Mm) alloys were measured at room-temperature as a function of extrusion temperature ranging from 523 K to 723 K. The σUTS, Hv decease and εp increases with increased extrusion temperature. The σUTS and εp were 592 MPa and 7.3 %, respectively, for the P/M Al<SUB>94.5</SUB>Cr<SUB>3</SUB>Ce<SUB>1</SUB>Co<SUB>1.5</SUB> alloy and 775 MPa and 2%, respectively, for the P/M Al<SUB>93.5</SUB>Cr<SUB>3</SUB>Ce<SUB>1</SUB>Co<SUB>1.5</SUB>Mn<SUB>1</SUB> alloy. The σUTS remained almost unchanged by the substitution of Mm for Ce. The σUTS, εp, Young's modulus (E) and Hv of the P/M Al<SUB>94</SUB>Cr<SUB>3</SUB>Mm<SUB>1</SUB>Mn<SUB>1</SUB>Ti<SUB>1</SUB> alloy were 625 MPa, 3.3 %, 88 GPa and 190, respectively, at room-temperature and the σUTS, σ<SUB>0.2</SUB> and εp at 473 K were 403 MPa, 385 MPa and 2.5 %, respectively.
