dc.description.abstractIN THIS WORK, A BLEND OF TI, NB, AND MN POWDERS, WITH A NOMINAL COMPOSITION OF 15 WT.% OF MN, AND BALANCED TI AND NB WT.%, WAS SELECTED TO BE MECHANICALLY ALLOYED BY THE FOLLOWING TWO ALTERNATIVE HIGH-ENERGY MILLING DEVICES: A VIBRATORY 8000D MIXER/MILL® AND A PM400 RETSCH® PLANETARY BALL MILL. TWO BALL-TO-POWDER RATIO (BPR) CONDITIONS (10:1 AND 20:1) WERE APPLIED, TO STUDY THE EVOLUTION OF THE SYNTHESIZED PHASES UNDER EACH OF THE TWO MECHANICAL ALLOYING CONDITIONS. THE MAIN FINDINGS OBSERVED INCLUDE THE FOLLOWING: (1) THE SEQUENCE CONVERSION EVOLVED FROM RAW ELEMENTS TO A TRANSITORY BCC-TINBMN ALLOY, AND SUBSEQUENTLY TO AN FCC-TINB15MN ALLOY, INDEPENDENT OF THE MILLING CONDITIONS; (2) THE TOTAL FULL CONVERSION TO THE FCC-TINB15MN ALLOY WAS ONLY REACHED BY THE PLANETARY MILL AT A MINIMUM OF 12 H OF MILLING TIME, FOR EITHER OF THE BPR EMPLOYED; (3) THE PLANETARY MILL PRODUCED A NON-NEGLIGIBLE FE CONTAMINATION FROM THE MILLING MEDIA, WHEN THE HIGHEST BPR AND MILLING TIME WERE APPLIED; AND (4) THE FINAL FCC-TINB15MN ALLOY SYNTHESIZED PRESENTS A NANOCRYSTALLINE NATURE AND A PARTIAL DEGREE OF AMORPHIZATION.
