The initial months of the existence of the Task Group on Brittle Failure were spent in consideration of those failures of rotor forgings which were responsible for bringing the group into being. It should be understood that the task group is a part of Subcommittee VI on Steel Forgings and Billets, of ASTM Committee A-1 on Steel, which is responsible for the preparation and maintenance of all specifications needed for this product. It is interesting to note that another task group, on Hydrogen in Steel Forgings, set up six years ago, has done indispensable work in standardizing methods of determining the hydrogen content of steel and, in particular, in standardizing the method of sampling steel forgings for hydrogen content. It may be expected that the task group will make whatever recommendations are necessary to ascertain that the Society takes proper cognizance of the possibility of brittle fracture in steel forgings and provides means in specifications for determining relative susceptibility to brittle failure.
