The Mechanical and Chemical Properties of the HY 100 Pressure Hulls of the Submarine, Alvin

摘要

This report presents mechanical and chemical test data from the three pressure hulls fabricated for the Deep Research Submarine, ALVIN. The data is discussed briefly, the low Charpy V-Notch values after stress relief noted, and recommendations made for further testing required for design and evaluation. The three hulls are compared with reference to failure criteria. (Author)
