Strength and Plastic Properties of TiNiMoFeCu Alloys

В работе исследованы пористые сплавы TiNi49,9-xMo0,1Fe0,1Cux(где x = 0, 1, 3, 6, 10 ат.%), полученные методом (СВС). Показано, что существенное влияние на формирование поверхностей разрушения оказывает сформированная структура сплавов. Установлено, что многообразие проявления свойств сплавов с увеличением легирующей добавки от 1 до 10 ат.% Cu определяется как составом материала, так и температурой деформации.In this work, porous alloys TiNi49,9-xMo0.1Fe0.1Cux (where x = 0, 1, 3, 6, 10 at.%) Obtained by the (SHS) method are investigated. It is shown that the formed structure of the alloys has a significant effect on the formation of fracture surfaces. It was found that, the variety of properties of properties of alloys with the alloying additive formula from 1 to 10 at.% Cu is determined by both the composition of the material and the temperature of deformation.Исследование выполнено за счет гранта Российского научного фонда (проект № 19-79-10045).The research was carried out at the expense of a grant from the Russian science foundation (project No. 19-79-10045)

The structure and properties of functional titanium nickelide-based TN-10, TN-20, and TN-1V alloys

The interrelation among the structural features, martensitic transformation characteristics, and physical-mechanical properties of functional titanium nickelide-based TN–10, TN–20, and TN–1V alloys is investigated. Martensitic transformations in a TN–10 alloy at temperatures of 273 and 298 K are found to develop at lower martensite shear stresses than in TN–20 and TN–1V alloys. This is due to the internal structure formed in the production of the material. The degree of ultimate strain and the magnitude of ultimate stress for each of the alloys depend on the state of the matrix at a pre-assigned deformation temperature and on the contribution of the martensitic transformation mechanisms of deformation under applied load. The structure formed and the plastic component of deformation are shown to exert a dramatic effect on the type and characteristics of fracture
