Theoretical study of the elastic and thermodynamic properties of Pt_{3}Al with the L1_{2} structure under high pressure

Abstract: In this work, the elastic and thermodynamic properties of Pt 3 Al under high pressure are investigated using density functional theory within the generalized gradient approximation. The results of bulk modulus and elastic constants at zero pressure are in good agreement with the available theoretical and experimental values. Under high pressure, all the elastic constants meet the corresponding mechanical stability criteria, meaning that Pt 3 Al possesses mechanical stability. In addition, the elastic constants… Show more

“…The superalloy Pt3Al, has proved an interesting material for both ab-initio (Yu et al, 2004;Chauke et al, 2010;Wei et al, 2015) and molecular dynamic (MD) simulations. The density of Pt3Al is about 16 g/cm 3 and this has limited its wide use.…”

“…В ка-честве модельного сплава рассматривается сплав Pt 3 Al. Материалы платиновой группы представляют большой интерес в связи с высокой температурой плавления, высокой прочностью и исключительной устойчивостью к условиям окружающей среды [59][60][61]. Атомы взаимодействовали посредством парного по-тенциала Морзе Передача энергии от потока частиц атомам решетки моделируется увеличением импульсов определенной до-ли случайно выбранных атомов C в направлении [100] на заданную величину, так, что кинетическая энергия каж-дого из выбранных атомов получает мгновенное прира-щение E. Такая процедура выполняется периодически с интервалом времени T .…”
