Machining-Induced Deformation in Stepped Specimens of Ph 13-8 Mo, 18 Nickel Maraging Steel Grade 200T1 and Grain-Refined HP 9-4-20

摘要

The results of a study to evaluate the dimensional changes created during machining and subsequent cycling to cryogenic temperatures for three different metallic alloys are presented. Experimental techniques are described and results presented for 18 Ni Grade 200 maraging steel, PH-13-8 Mo stainless steel, and Grain-refined HP 9-4-20.
