Paper Title:
Investigation of the Fatigue Behavior of AlMg4.5Mn (EN AW-5083) in the Temperature Range -60 °C < T < 20 °C
  Abstract

Stress-controlled load increase and constant amplitude tests have been carried out in a temperature range of -60°C < T < 20°C at the aluminium alloy AlMg4.5Mn (EN AW-5083). Therefore a recently developed climate chamber which operates with liquid nitrogen was mounted on a servo-hydraulic fatigue testing machine to realize the required low temperatures. Beside conventional mechanical hysteresis measurements, electrical resistance and temperature measurements are used to characterize the fatigue behavior. Furthermore, with these methods, the endurance limit was successfully estimated in a load increase test. Woehler curves were determined with constant amplitude tests at different temperatures. The conventionally determined endurance limit corresponds with the value from the load increase test.
