Abstract
Optical microscopy and scanning electron microscopy (SEM) were used to exam ine the fracture behavior of AZ91 magnesium alloy ruptured by tensile and i mpact tests. AZ91 alloy generally revealed features of brittle fracture and cleavage is the principal fracture mode. The fracture behavior for tensile test is different from that for impact test due to different load forms. T he fracture morphologies are different in different areas of the impact spe cimen. The Mg/Mg17Al12 interface often acted as the crack initiation source . (C) 2000 Elsevier Science B.V. All rights reserved.
