摘要

The influence of systematic variations of chemical composition on rupture properties at 1200° F was determined for 62 modifications of low-carbon N-105 alloy. These modifications included individual variations of each of the 10 elements present in low-carbon N-155 and simultaneous variations of molybdenum, tungsten, and columbium. Laboratory induction furnace heats of the alloys were hot-forged to round bar stock, solution-treated at 2200° F, and aged at 1400° F. The melting and fabrication conditions were carefully controlled in order to minimize all variable effects on properties except chemical composition.
