Abstract
Ribbons of Al-Fe-Ti-M(M=V, Cr, Mn)alloys were prepared by melt-quenching(MQ)and their bulk alloys by the powder metallurgy(P/M)method using atomized powders. The ribbon Al-Fe-Ti-M(M=V, Cr, Mn)alloys produced at the circumferential velocity (Vc) of 40 m/s consisted of fcc-Al and amorphous phases. Maximum tensile fracture strength (σf) of the Al-Fe-Ti-M ribbons was 1170 MPa for Al93Fe3Ti2V2 alloy. The constituent structure was nearly the same as those for the powder and bulk Al-Fe-Ti-M(M=V, Cr, Mn)alloys. The bulk Al93Fe3Ti2Cr2 alloy consisted of quasicrystalline particles dispersed into fcc-Al. Decomposition temperature of these particles was 740 K. The ultimate tensile strength, 0.2% proof sterngth, plastic elongation, Young's modulus and Vicker's hardness were 650 MPa, 530 MPa, 4.4 %, 86 GPa and 190, respectively.
