A study of microstructure and fatigue behaviour of A3003 alloy

Popis výsledku v původním jazyce

A study of A3003 aluminium alloy in H12 temper regarding microstructure analysis, tensile testing, fatigue loading and fractography of fracture surfaces was carried out. Specimens were cyclic loaded at five stress amplitude levels of 62, 68, 70, 72 and 76 MPa so that the results for both the low cycle fatigue and high cycle fatigue are obtained. During loading of the specimens at the highest stress amplitude the specimens resembled quasi-static fracture with necking usually seen in tensile testing. In our case, the stress amplitude of 72 MPa can be considered transient as the failure went from quasi-static fracture to fracture with typical signs of fatigue. The 68 MPa stress amplitude appears as a transition from LCF to HCF. Testing at the lowest stress amplitude was stopped after 107 cycles without failure of the material so it can be regarded as fatigue limit for this alloy. Wrought microstructure was observed using optical microscopy and present phases were identified by EDX analysis as Al6FeMn and α-Al12(Fe,Mn)3Si. The microstructure of H12 temper was compared with the same alloy in F state.
