Uticaj strukture na sposobnost oblikovanja Al-Mg6,8 legure / Influence of microstructure on the formability of Al-Mg6.8 alloy
(Association of Chemical Engineers of Serbia, 2008)
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 ...
Study of the simulated heat affected zone of creep resistant 9-12% advanced chromium steel
(Taylor & Francis Inc, Philadelphia, 2008)
Global warming leads to research-development attempts worldwide with a view to reduce CO2 emission. Therefore, in the energy supply sector, a special focus has been directed to further development of steels that can endure ...
Application of instrumental methods in the investigation of properties and microstructure of construction concretes / Primena instrumentalnih metoda za ispitivanje svojstava i mikrostrukture konstukcionih betona
(Savez inženjera metalurgije Srbije, Beograd, 2008)
Methods for the investigation of microstructure of construction concretes are presented in this paper. Concrete is a composite material, thus its microstructure consists of bonding agent (cement) and aggregate with predefined ...
The effect of compositional variations on the fracture toughness of 7000 al-alloys
(Institute of Metals and Technology, 2008)
To provide an understanding of how compositional variations affect the microstructural parameters associated with coarse intermetallic (IM) particles and the fracture toughness in AA 7000 aluminum forgings, a microstructural ...
Characterization of microstructural changes in an Al-6.8 wt.% Mg alloy by electrical resistivity measurements
(Elsevier Science Sa, Lausanne, 2008)
Microstructural changes in an AlMg6.8 alloy after different thermo mechanical (TMT) and sensitization treatments were investigated by electrical resistivity measurements. The electrical resistivity was most affected by the ...
Micromechanical model for fracture toughness prediction in Al-Zn-Mg-Cu alloy forgings
(Taylor & Francis Ltd, Abingdon, 2008)
An attempt has been made to model the plane-strain fracture toughness, KIc, in Al-Zn-Mg-Cu alloy forgings subjected to overageing. The proposed model, based on the multiple micromechanisms, reveals the quantitative relations ...
Microstructural dependence of fracture toughness in high-strength 7000 forging alloys
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The effects of microstructural parameters associated with the coarse intermetallic phases particles and precipitates on the fracture toughness of the overaged 7000 alloy forgings are investigated. Detailed microstructural ...
