PREPARATION AND INVESTIGATION OF HIGH STRENGTH WIRES.
Abstract
An investigation was conducted to determine the effect of oxide coatings on the mechanical properties of iron wires. The most desirable oxide coatings were formed at 600 and 700 C for a controlled argon-hydrogen-water vapor atmospheres in which only wustite (FeO) was stable. During mechanical testing of oxidized wires, the following factors were found to increase the strength levels of the wires: (1) decreasing the annealing time prior to oxidation; (2) increasing the oxidizing time; (3) decreasing the oxidizing temperature; and (4) increasing the strain rate. Thirty to 40% of the strengthening of the oxidized wires was found to be a consequence of oxide-dislocation interactions and 60 to 70% was due to higher carbon, oxygen, nitrogen, and hydrogen contents in the oxidized specimens.
