Гордеев, Юрий Иванович. Effect of liquid-phase sintering as a means of quality enhancement of pseudoalloys based on copper [Текст] / Юрий Иванович Гордеев, Артур Карлосович Абкарян, Галина Михайловна Зеер, Анатолий Александрович Лепешев, Елена Геннадьевна Зеленкова // Journal of Physics: Conference Series: Conference Series. — 2017. — Т. 803 (№ 1). — С. 012050Аннотация:
The effects of liquid phase of metal binder on the microstructure and
properties of self-diffusion gradient composite (Cu - Al – ZnO) were investigated. For
the compositions considered, it was revealed that at the temperature near 550 °C liquid
phase binder from nanoparticles Cu – Al formed. Applying a proper amount of (Cu –
Al) binder appeared to be beneficial for fabricating gradient composites with desired
self-diffusion process and mass transfer of additives nanoparticles into volume of
matrix during sintering and the desired fine microstructure and mechanical properties.
For the experimental conditions considered in this study, the best mechanical
properties can be obtained when 6 mass % (Cu – Al) ligature were used, which gave
hardness HB at 120, electroerosion wear – 0.092 • 10-6 g / cycle, electroresistivity –
0.025 mkOm.
