Despite the extensive use of Type 347 stainless-steel tubing for regeneratively cooled thrust chambers, very little is known about its grain growth characteristics. Lacking, also, is information on the other 18 Cr8 Ni austenitic steels. Therefore,

Hitherto it has been considered that the pyrolytic particles present in pitch as a result of high temperature cracking accelerate the formation of mesophase by the nucleation process. It has been demonstrated by optical and hot stage microscopy that
