dc.description.abstract | U ovom radu korišćena je aluminijum-magnezijum legura sa 6,8% magnezijuma (Al-Mg6,8), koja pripada grupi Al-Mg legura visoke čvrstoće. Ispitivan je uticaj mikrostrukture, koja se postiže primenom različitih uslova termomehaničke obrade (TMO), na deformaciono ponašanje pri jednoosnom zatezanju, i na sposobnost oblikovanja u uslovima složenog naponsko-deformisanog stanja. Najbolju sposobnost oblikovanja, koja je ocenjena na osnovu parametara ojačavanja u toku jednoosnog zatezanja, i na osnovu graničnih krivih oblikovanja (GKO), konstruisanih po kriterijumu lokalnog stanjivanja i granične visine kupole (GVK), pokazuje ispitivana legura sa rekristalisanom jednofaznom a-Al i/ili dvofaznom (a + β) strukturom. | sr |
dc.description.abstract | Formability of Al-Mg6.8 alloy has been evaluated experimentally in uniaxial tension and biaxial stretching. Three different structures developed after cold rolling and annealing in the range of temperature from 265 to 320 °C: (I) recovered dual (a + β) phase, (II) recrystallized (a + β) dual phase, and (III) recrystallized a-Al single phase structure, were tested. Samples with recovered structure have shown a lower formability level than the samples with fully recrystallized structure. Formability level assessed through FLD and LDH value, has been a result of complex interaction between work hardening ability and strain rate sensitivity. | en |
