The influence of titanium and cerium on microstructure and properties of Fe-C-Cr-Nb alloys
Uticaj titana i cerijuma na mikrostrukturu i svojstva Fe-C-Cr-Nb legura
Апстракт
In this paper, the influence of titanium and cerium on the microstructure and properties of Fe-C-Cr-Nb alloys are examined, in both as-cast and heat treated state. These elements affect the crystallisation process of Fe-C-Cr-Nb alloys and the transformation of austenite during the cooling process after solidification. Titanium changed the morphology of NbC carbides. Further, in the austenite of the examined Fe-C-Cr-Nb-Ti alloys, very fine particles of precipitated secondary carbide can be seen. The alloy containing 0,28%Ti and 0,19%Ce has martensite-perlite-austenitic matrix microstructure in as-cast condition. Adding titanium and cerium to Fe-C-Cr-Nb alloys will also changed its properties, since the properties of alloys depend on their microstructure.
U ovom radu ispitivan je uticaj titana i cerijuma na mikrostrukturu i svojstva Fe-C-Cr-Nb legura, u livenom stanju i nakon termičkog tretmana. Ovi elementi utiču na proces kristalizacije Fe-C-Cr-Nb legura, kao i na transformaciju austenita u toku daljeg hlađenja nakon očvršćavanja. Titan menja morfologiju NbC karbida. Osim toga, u austenitu ispitivanih Fe-C-Cr-Nb-Ti legura zapažaju se vrlo fine čestice sekundarnog karbida. Legura koja sadrži 0,28%Ti i 0,19%Ce ima martenzitno-perlitno-austenitnu mikrostrukturu osnove u livenom stanju. Titan i cerijum utiču i na svojstva Fe-C-Cr-Nb legura, budući da svojstva legura zavise od njihove strukture.
