The analysis of the tribological properties of multiple strengthened nanocomposite of the Cu-Al2o3 system
(Savez inženjera metalurgije Srbije, Beograd, 2011)
This paper presents the results of examined tribological properties of the multiple strengthened nanocomposite Cu-Al2O3 system. Cu-Al2O3 composite powder was obtained by combination of the thermo-chemical procedure and ...
Modern steels: Transformation induced plasticity / Savremeni čelici - transformacijom izazvana plastičnost
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2011)
TRIP čelici danas zauzimaju značajno mesto u komercijaloj upotrebi u vozilima i konstrukcijama kod kojih je jedan od glavnih zahteva redukcija sopstvene težine. Optimalna kombinacija udela stabilisanog austenita i stepen ...
