Manufacturing Methods for Producing L-605Hardware.

摘要

The report summarizes a program designed to develop a process for producing large components for rocket/ramjet combustion chambers by cold shear spinning forged L-605preforms. Phase I of the program involved work performed on six experimental heats of L-605directed toward optimization of melting process,composition tolerances, fabricability,response to thermal treatments,and mechanical properties. This work resulted in an improved specification for L-605forgings of shear spinning quality. Phase II of the program involved shear spinning process development for production of SCP/LASRM combustion chamber center sections which resulted in a L-605shear spinning process specification. In addition,an attempt was made to shear spin a centrifugally cast preform. (Author)
