Abstract:

A capacitor-discharge pulse heating and quenching system, called the Pulsar, has been built and made operative at the Watervliet Arsenal. Metallic samples, up to 110 inch in cross sectional area, may be heated at 1,000,000 Csec held at temperature from 15 to 500 millisec, and then spary water quenched at 10,000 C sec. This allows metallurgical reactions, such as dissolution, grain refinement, and constitutional liquation to be studied before completion. The system enables one to separate out the effects of temperature from the other metallurgical mechanical and chemical effects that a gun tube undergoes during a firing cycle.
