Effect of Environments of Sodium Hydroxide, Air, and Argon on the Stress-Rupture Properties of Nickel at 1500 Degrees F

Description: Note presenting the stress-rupture properties of commercially pure nickel at 1500 degrees Fahrenheit as determined for its application as a container material for molten sodium hydroxide. Stress-rupture tests of L-nickel tubes containing sodium hydroxide were run with atmospheres of air or argon external to the tubes. Sodium hydroxide was found to have little effect on the stress-rupture strength of nickel tubes tested in argon at 1500 degrees Fahrenheit for times up to 200 hours.

Corrosion Resistance of Nickel Alloys in Molten Sodium Hydroxide

Description: Note presenting a study of the corrosion resistance of 11 nickel-base compositions to molten sodium hydroxide at 1500 and 1700 degrees Fahrenheit in order to find a container material for the caustic at these temperatures. Results are provided for the solid-solution alloys, nickel with mechanically dispersed second phase materials, and the precipitation-hardened alloy.

The Mechanism of Thermal-Gradient Mass Transfer in the Sodium Hydroxide-Nickel System

Description: Note presenting an investigation of thermal gradient mass transfer in the molten sodium hydroxide-nickel system. Possible mechanisms, including physical, electrochemical, and chemical, are discussed in terms of experimental and theoretical evidence. Kinetic equations are theoretically derived considering separately the follwing three factors as controlling overall rate of mass transfer: the chemical reaction, the diffusion process, and the forced circulation.

Combustion-engine temperatures by the sodium line-reversal method

Description: The sodium line-reversal method has been used in some preliminary measurements of flame temperature. Improvements in the method involving a photographic recorder and a means of correcting for the dirtiness of the windows are described. The temperatures so obtained are compared with those calculated from pressure diagrams.
