DESCRIPTION:Speakers: Mphamela Enos Baloyi (University of Limpopo)\nIn thi
 s study\, the phase stability of B2 and B19 Ti50Pt43.75-xCoxTa6.25 structu
 res using ab initio density functional theory approach was investigated. T
 heir structural\, vibrational and mechanical properties were determined to
  show their stability. The supercell approach was employed to substitute P
 t with Ta on the TiPtCo and evaluate the stability of the structures. The 
 calculated heats of formation predicted Ti50Pt37.50Co6.25Ta6.25 to be the 
 most stable structures as compared to other concentrations for both B2 and
  B19 systems. The calculated elastic properties show that TiPtCoTa is mech
 anically stable at different concentrations of Co. Moreover\, the temperat
 ure dependence was also calculated to predict the possible transformation.
