Title

TO STUDY THERMODYNAMICS AND PHYSICAL BEHAVIOR OF PB IN AL-PB SYSTEM FABRICATED BY MECHANICAL ALLOYING

Pages

  91-101

Abstract

 In this research, Al and Pb powders (25 wt% Pb) were subjected to MECHANICAL ALLOYING, using a planetary ball mill. The ball milled mixture was studied by scanning electron microscope (SEM), equipped by EDS. To study thermal behavior, DSC experiments were performed and variation of melting temperature of Pb by ball milling was investigated. In addition, solid solubility of Pb in Al was studied during ball milling. Despite this fact that based on equilibrium phase diagram there is no solid solubility in AL-PB SYSTEM, formation of a non equilibrium solid solution of Pb in Al and also a reduction in MELTING POINT of Pb by ball milling could be observed. During heating-up of ball milled samples, very fine particles of solute Pb were precipitated at about 300 oC, which caused in lowering of MELTING POINT of Pb. MELTING POINT of Pb decreased from 327.25 oC for un-milled to 316 oC in 48 hours milled sample and also the solved Pb in Al matrix increased from 0.65 wt% for 5 hours milled sample to 0.89 wt%in 48 hours milled sample.
