24. Strategies of the Cold Start of Polymer Electrolyte Membrane Fuel Cells.

Author

Grigor'ev, S. A. and Klimova, M. A.

Subjects
PROTON exchange membrane fuel cells, DEBYE temperatures, TEMPERATURE effect
Abstract

Processes proceeding in polymer electrolyte membrane fuel cells at negative temperatures were investigated. Mechanisms of degradation of the active electrocatalytic layers and gas-diffusion electrodes of these cells in the case of freezing of the water in them were considered. Methods of decreasing or excluding the detrimental effect of negative temperatures on the characteristics of the indicated cells and engineering solutions on the provision of their cold start have been proposed.

33. Evolution of microstructure and mechanical properties of Ti-based metal-matrix composites during hot deformation

Author

Subjects
Engineering (General). Civil engineering (General), TA1-2040
Abstract

Two Ti-based composites, viz. Ti/TiB and Ti-15Mo/TiB were produced by spark plasma sintering using a Ti-10wt.%TiB2 powder mixture at 1000°C or Ti-14.25(wt.)%Mo-5(wt.)%TiB2 powder mixture at 1400°C, respectively. Specimens of the metal-matrix composites (MMCs) were subjected to uniaxial compression in the temperature range from 500 to 1050°С to determine processing window. Processing maps for both MMCs were constructed and analyzed. Mechanical behavior and microstructure evolution of both MMCs during multiaxial forging (MAF) at 700°C and at a strain rate 10-3 s-1 were studied. The flow stress for the Ti-15Mo/TiB MMC during MAF was ∼2 times higher than that for the Ti/TiB composite. Microstructure evolution during MAF of Ti/TiB MMC was associated with continuous dynamic recrystallization of the titanium matrix and shortening of TiB whiskers by a factor of ~3. The Ti-15Mo/TiB composite microstructure after did not demonstrate the development of recrystallization.

Abstract

Высокоэнтропийные сплавы Fe40–xMn40Co10Cr10Nх после холодной прокатки отжигались в интервале температур 700–1000 °C в течение 10 мин. В сплавах происходило выделение сигма-фазы, объемная доля которой уменьшалась как при увеличении температуры отжига, так и при повышении концентрации азота. Прочность сплавов уменьшалась с повышением температуры отжига, пластичность при этом росла. High entropy Fe40–xMn40Co10Cr10Nх alloys after cold rolling were annealed at 700–1000 °C for 10 minutes. Sigma phase precipitated in the alloys, and the volume fraction of the phase decreased both with an increase in the annealing temperature and with an increase in the nitrogen concentration. The strength of the alloys decreased with increasing annealing temperature, while ductility increased. Работа выполнена при финансовой поддержке Российского научного фонда, грант №18-19-00003.
