Investigation of minimum creep rates and stress exponents calculated from tensile and compressive creep data of magnesium alloy AE42 [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2009 Abstract Creep specimens prepared of magnesium alloy AE42 were investigated under constant load in compressive and in tensile creep. Material was cast via the squeeze casting process in order to obtain a dense microstructure without pores. Creep tests were performed at constant temperatures between 150 °C and 240 °C and constant applied stresses ...

Creep strength and minimum strain rate estimation from Small Punch Creep tests
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2018 A new standard is currently being developed under the auspices of ECISS/TC 101 WG1 for the small punch testing technique for the estimation of both tensile and creep properties. Annex G of the new standard is covering the assessment and evaluation of small punch creep (SPC) data. The main challenge for estimating uniaxial creep properties from SPC data

On the development of creep damage constitutive equations: a modified hyperbolic sine law for minimum creep strain rate and stress and creep fracture criteria based on cavity area fraction along grain boundaries [PDF]
Materials at High Temperatures, 2017 Abstract: This paper reports 1) the latest development and application of modified hyperbolic sine law for minimum creep strain rate and stress for both low Cr and high Cr steels, and 2) the development of creep fracture criterion based on cavity area fraction along grain boundary for high Cr steel.

ISIJ International, 2012 The stress exponent of the minimum creep rate, n, and the activation energy of creep, Qc, were obtained for the oxide dispersion-strengthened nickel-based superalloy MA754 by conducting creep tests at 1223–1273 K in the stress range of 130–190 MPa. The values of n and Qc in MA754 were determined to be 26 and 962 kJ/mol, respectively.

The rupture life prediction in cold dwell fatigue of Ti-6Al-4V based on the creep deformation [PDF]
MATEC Web of Conferences, 2020 Titanium a lloys have been found that the fatigue strength of Ti alloys decreases due to cold dwell fatigue (CDF) at room temperature. Ti and Ti alloys generate creep deformation at room temperature (T/Tm = 0.15).
