Development and Production of Experimental High-Strength Ferritic Electrodes.

Abstract

The objective of this investigation was to investigate the suitability of the notched bend specimen for evaluating the toughness of welded butt joints made in armor plate with high-yield-strength ferritic electrodes and as a substitute for the ballistic H-plate. Bend tests of notched specimens of butt joints were made at different rates of loading over a temperature range from approximately 400 F to -290 F. The welds were made with high-yield-strength ferritic electrodes and an austenitic chromium-nickel steel electrode in 3/4-inch and 1-1/2-armor. These tests were to ascertain the effects of strain rate and plate thickness on the plastic behavior of the specimen and its suitability for evaluating the energy-absorbing capacity of various weld metals in armor joints. The increase in specimen thickness shifted the transition from shear to cleavage behavior to higher temperatures, though tests with the different rates of loading indicated no significant change in this transition. However, the behavior at ballistic velocities has not yet been determined.
