This report presents the results obtained to date of an investigation to establish the fundamental causes of abnormal grain growth in S-816 alloy under conditions encountered during the forging of blades for the gas turbine of jet engines. The data reported are confined to the experiments conducted to learn how to produce abnormally large grains in bar stock under controlled conditions. These are being reported because they may be useful to those concerned with the problem.
