Title

THE EFFECT OF VARIOUS PARAMETERS ON OUT-OF-PHASE THERMO-MECHANICAL FATIGUE LIFETIME OF A356.0 CAST ALUMINUM ALLOY

Pages

  1461-1470

Abstract

 In this paper, the effect of various parameters on the out-of-phase THERMO-MECHANICAL FATIGUE (OP-TMF) lifetime of the A356.0 cast aluminum alloy is investigated. Studied parameters include the MAXIMUM TEMPERATURE, the DWELL TIME, and the thermo-mechanical loading factor. OP-TMF tests are conducted considering realistic running conditions of diesel engine cylinder heads. The MAXIMUM TEMPERATURE varies between 200 to 275oC and the thermo-mechanical loading factor, which is the ratio of the mechanical strain to the thermal strain, is considered between 75 to 150%. The DWELL TIME (or the holding time) changes between 5 to 180 sec. at the MAXIMUM TEMPERATURE. Fracture surfaces of specimens are studied using the scanning electron microscopy (SEM). These SEM images reveal that the A356.0 alloy has a ductile behavior. The CYCLIC SOFTENING phenomenon is also observed during stress-strain hysteresis loops. TMF test results demonstrate that the DWELL TIME bears no significant effect upon the lifetime. However, large influences for the MAXIMUM TEMPERATURE and the thermo-mechanical loading factor are depicted in the lifetime of the A356.0 alloy.
