Description

The forged aluminum alloy axle box is used for **0 km/hour high speed train , The tensile and fatigue properties of the ***0 aluminum alloy used for the die forging axle box of high speed train were measured and analyzed. The experimental results showed that the tensile strengths and ductilities of the specimens parallel to extension of metal during forging (L specimen) were higher than that of the specimens perpendicular to the direction of the extension of metal (T specimen) . And the fatigue limit of the specimens parallel to extension of metal during forging (L specimen) )was D=**0 Mpa, which was higher than that of the specimens perpendicular to the direction of the extension of metal (T specimen)i.e., the fatigue limit of the T specimens was D=**8.3 MPa. The fracture surface morphology obvervation revealed that the fracture surface of L specimens were dimple, but the fracture surfaces of T specimens were intergranular.
