INVESTIGATION OF THE NOTCH SENSITIVITY OF NICKEL COPPER ALUMINUM (K-MONEL) ROD
NAVY MARINE ENGINEERING LAB ANNAPOLIS MD
Pagination or Media Count:
Tensile and notch tensile properties of K-monel processed by different fabrication techniques were investigated. Material processed by standard hot rolling and cold drawing was found to meet the ductility and strength requirements of military specifications. A drastic 30 final cold reduction, followed directly by aging, lowered the percent of elongation below requirements of military specifications, but did not lead to weakness or brittleness of notched specimens. Extruding of small ingots with insufficient reduction of area led to material with low strength and brittleness.
