Abstract
Heavy section cast GJS 400 nodular iron was studied. In
ultrasonic factory inspection rejected and acceptable
material blocks were evaluated by further ultrasonic
measurements, radiography and fatigue testing.
Radiography was capable to recognize porosity, but the
sizes of individual pores could not be assessed. The
defected area map of factory inspection resembles the
C-scan image produced by semi-manual inspection using BAT
method.
Fatigue tests show a notable difference in fatigue
resistance of the acceptable and rejected materials for
50 % failure probability, but the scatter was clearly
higher in the acceptable material batch, meaning that
reduction of safe fatigue design curve may be much
smaller than the difference at 50 % failure probability.
