A STUDY OF THE STRAIN-AGE CRACK SENSITIVITY OF RENE' 41

Abstract

A program of research work directed toward the study of the strain- age crack sensitivity of Rene' 41 was conducted and is described. The primary objectives of this study were: To perfect a screening test which could be used to evaluate and quantitatively measure factors which contribute to strain-age cracking in complex nickel-base superalloys and To subsequently use this information as a means of improving material quality and welding and heat treating process techniques and procedures which would minimize or eliminate the occurrence of strain-age cracking in fabricated components. Of the various factors studied, low carbon (0.04 - 0.02%) and electron beam welding were documented as being the most capable of decreasing the sensitivity of Rene' 41 to strain-age cracking. Further studies are planned under a continuation of this contract.
