Small-Diameter Wire Tensile Testing: Topical Report

摘要

Tests were conducted on small-diameter wire (0.025 cm) per AMS 5834 to determine effects on yield and tensile strengths. Straight and coiled wire samples were heat-treated in vacuum, nitrogen, and hydrogen atmospheres to compare their effects on tensile properties. Surface flaws, strain rate sensitivity, and extensometer effects were also studied. Eight samples were included in scanning electron microscopy (SEM) fractography to document fracture mode variations. 13 figs., 2 tabs. (ERA citation 12:049817)
