PRODUCTION OF Fe3Al INTERMETALLIDE BY POROUS METALLURGY METHODS
In this paper we were investigated the possible ways of obtaining intermetallic Fe3Al for different methods of powder metallurgy. It is shown that the impact sintering of powder mixtures Fe + 14Al, Fe + 15Al at temperatures of 1050 and 1150 ° C allows to obtain non-porous samples, while the free sin...

Ceramics: Science and Life| Резюме: | In this paper we were investigated the possible ways of obtaining intermetallic Fe3Al for different methods of powder metallurgy. It is shown that the impact sintering of powder mixtures Fe + 14Al, Fe + 15Al at temperatures of 1050 and 1150 ° C allows to obtain non-porous samples, while the free sintering at temperatures of 1400 and 1450 ° C results in a sample with a porosity of 15 and 6% respectively. It is found that the use of impact sintering and hot forging allows to obtain a solid intermetallic Fe3Al with higher mechanical properties compared to the free sintering. It is shown that a change of the structure leads to a change the mechanical properties. |
