A Method of Determining the Equilibrium Performance and the Stability of an Engine Equipped With an Exhaust Turbosupercharger

"The performance of an exhaust turbine driving a supercharger is investigated by means of a sample calculation based on reasonable assumptions for the purpose of determining whether the assumed installation is stable with respect to changes in the mass of gas handled, boost pressure, etc. The arrangement was found to be stable throughout the entire range of operation. The method developed can be generally applied" (p. 1).

Relief of Residual Stress in Streamline Tie Rods by Heat Treatment (open access)

Relief of Residual Stress in Streamline Tie Rods by Heat Treatment

"About two-thirds of the residual stress in cold-worked SAE 1050 steel tie rods was relieved by heating 30 minutes at 600 degrees Fahrenheit. Cold-worked austenitic stainless-steel tie rods could be heated at temperatures up to 1000 degrees Fahrenheit without lowering the important physical properties. The corrosion resistance, in laboratory corrosion test, of straight 18:8 and titanium-treated 18:8 materials appeared to be impaired after heating at temperatures above 800 degrees or 900 degrees Fahrenheit" (p. 1).
