Summary:

Preliminary results are presented from an investigation to establish the fundamental causes of abnormal grain growth in S-816 alloy under conditions encountered during forging of blades for aircraft gas turbines. The data are confined to experiments to produce abnormally large grains in bar stock under controlled conditions. it was found that the critical deformation for grain growth is apparently independent of temperature of deformation; repeated critical deformations between reheats to 2150 degrees F produce much larger grains than a single critical deformation; grain growth characteristics are sensitive to prior history; and abnormal grain growth can be induced by temperature cycling alone to temperatures of 2150 degrees F with prior histories.
