Book excerpt: Although much information on high-temperature tensile and stress-rupture properties for various columbium-base materials is readily available, only limited information concerning the more useful creep behavior of columbium alloys has been reported. These data are widely scattered throughout the literature, and little attempt has been made to rationalize the creep behavior of columbium alloys. The purpose of this memorandum is to compile and review existing creep data for columbium alloys to gain insight into their merits and limitations for time-dependent structural service. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In work to develop materials for elevated temperature applications, binary niobium alloys containing either 2.37 wt% chromium, 3.34 wt% zirconium, or 5.21 wt% vanadium were fabricated to sheet by forging at 550 deg C and rolling at room temperature. All three alloys were completely recrystallized after 90% cold work (reduction in thickness) and a one hour anneal at 1150 deg C. Tensile tests on the annealed materials at 650, 800, 1000, 1150, and 1315 deg C indicated that chromium, zirconium, and vanadium are potent strengtheners of niobium. At 1000 deg C the 2.37 wt% chromium and the 5.21 wt% vanadium alloys had 0.2% offset yield strengths of 38,000 and 38,300 psi respectively. At 1315 deg C, the 3.34 wt% zirconium alloy had a 0.2% offset yield strength of 14,700 psi. Stresses to produce creep rates of 0.0001, 0.01, and 0.1% per hour were determined for all three alloys at 650, 800, and 1000 deg C. The vanadium alloy exhibited the greatest creep resistance, requiring stresses of 52,700, 40,000, and 15,500 psi to produce a creep rate of 0.001% per hour at 650, 800, and 1000 deg C respectively. This research indicated that significant improvement in the mechanical properties of niobium can be achieved by alloying without undue sacrifice of fabricability. (auth).

This book was released on 1965 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was made to evaluate two vanadium-base sheet alloys for aerospace applications in the 1,800 F to 2,400 F (1,260 K to l,590 K) temperature range. The investigation consisted of mechanical property tests both at room and elevated temperatures and oxidation tests on coated and uncoated material. Three silicide diffusion coatings were evaluated by continuous and cyclic oxidation testing to determine their protective qualities. An X-ray study, a metallographic examination, and hardness measurements were made to identify and locate the elements and compounds present in the coating and substrate before and after elevated-temperature exposure. Fabrication and joining of the alloys are discussed. A description of the equipment and procedures utilized in performing the evaluation tests is included.
