ABSTRACT: This paper examines the behavior of low carbon steels subjected to a frequency thermal cycling
test. A compositional analysis was performed to ascertain the percentage of carbon in the asreceived
materials. The specimens were machined to a precise gauge length and diameter and
exposed to various cycles of heat at each temperature. A fatigue test was also performed with the
use of Avery Dennison and bending stress was obtained using the curve supplied with the
machine. The results from the machine were converted to Mega Pascal (MPa) and the values
used to plot S-N curves and fatigue resistance for the specimens at various cycles and different
temperatures were established.
