In this experimental investigation, the tensile creep behavior of commercial-purity molybdenum sheet at temperatures between 1300°C and 1700°C is critically evaluated, based upon experimental creep testing and microstructural characterizations. The high-temperature properties of molybdenum are of interest because there are many applications in which molybdenum and molybdenum alloys are used at elevated temperatures. Understanding of the creep mechanisms and the constitutive relations between stress and strain at elevated temperatures is needed in order to determine if molybdenum is an appropriate choice for a given high-temperature design application and to accurately predict its creep life. The creep behavior of two commercially-available grades of molybdenum was determined using short-term creep tests (1/2 to 14 hours) at slow to moderate true-strain rates of 10⁻⁶ to 10⁻⁴ s⁻¹ and temperatures between 1300°C and 1700°C. High-temperature, uniaxial tensile testing was used to produce data defining the relationship between tensile creep strain-rate and steady-state flow stress at four temperatures: 1340°C, 1440°C, 1540°C, 1640°C. Microstructural changes that occurred during creep testing were evaluated and compared to changes resulting from elevated temperature exposure alone. Mechanisms for dynamic abnormal grain growth that occurred during creep testing and the causes of the microstructural changes that occurred as a function of temperature are discussed.

Not available. This is the link to a similar paper from 2004 in Acta Materials, September 6, 2004: Al2O3/Y-TZP particulate laminates with varying compositions and ratios of layer thickness were fabricated by tapecasting, lamination, and sintering. The resulting particulate laminates were tested in compression at a temperature of 1350 °C over strain rates from 1.00 × 10−5 to 3.16 × 10−4 s−1. Microstructural changes during testing were observed to be minor. Stress exponents were measured to be approximately two and are consistent with previous data for particulate composites. Using parameters determined from particulate composites, the behaviors of the particulate laminate composites are accurately predicted using a constrained isostrain model without additional fitting parameters.
