..., and tensile creep rupture. The CMC system consists of an aluminosilicate matrix reinforced with Nextel 610 fibers. The Nextel 610 fibers were in the form of an 8HSW. Results from the mechanical behavior studies showed this CMC to perform extremely well in fatigue at both room temperature and 1000°C. However...

... A titanium-modified austenitic type stainless steel was tested at three cold work levels to determine its creep and creep rupture properties under both thermal aging and neutron irradiation conditions. Both the thermal and irradiation creep behavior exhibit a complex non-monotonic relationship...

... of the newer grades of silicon nitride. The map is then used to compare this material with a high temperature structural alloy, and another, older grade of silicon nitride. Finally, we discuss the use of fracture mechanism maps for design. silicon nitride fracture mechanism maps creep creep rupture...

... A methodology is proposed to estimate creep rupture life for advanced ceramics such as continuous fiber reinforced ceramic matrix composites (CFCMC). Based on the premise that the damage pattern takes the form of a heterogeneous distribution of grain boundary cavities in the majority of creep...

... The effect of the interphase/interface region on the creep and creep rupture behavior of thermoplastic (J2) composites was investigated. The mechanical properties of the J2 composites were altered by systematic changes in fiber surface characteristics. The three fiber surface variations...

... the logarithm of time or cycles to failure are discussed in relation to current design practice. Some of the problems associated with creep and fatigue testing of silicone sealants are explained. silicone sealant creep rupture fatigue structural glazing L. Bogue Sandberg and Amy E. Rintala...

... A comparison of the susceptibility of different materials to helium embrittlement in in-beam creep rupture experiments (that is. thermal creep tests during helium implantation) at 873 K is presented. The materials used were a martensitic stainless steel. Deutsches Institut für Normung (DIN...

... In-reactor creep rupture data on one heat and two cold work levels of the D9-type alloy and on two heats of cold worked 316 stainless steel have been obtained from the Materials Open Test Assembly (MOTA) experiment in the Fast Flux Test Facility (FFTF). The on-line detection of creep ruptures...

... The capabilities of the Materials Open Test Assembly (MOTA) irradiation vehicle and the Fast Flux Test Facility (FFTF) cover gas monitoring system are described in relation to the creep rupture experiment during FFTF Cycle 2 operation. The creep rupture specimen matrix in MOTA includes both U. S...

... Creep rupture data in Kevlar 49 epoxy usually exhibit considerable scatter: the coefficient of variation (CV) about the mean failure time at a given stress often exceeds 100%. In this paper, analysis of existing creep rupture data on Kevlar epoxy vessels at four storage pressures has produced...

... from simple compositional modifications to a combination of chemistry modifications coupled with thermal mechanical processing. One such approach resulted in what is now commonly referred to as Super Waspaloy. Tension, low-cycle fatigue, and creep rupture tests of Waspaloy and Super Waspaloy forgings...

... The effect of helium on creep properties was studied in AISI Type 316 austenitic steels after two kinds of treatment, namely, cold rolling and grain-boundary strengthening. Helium was injected into the specimens using a cyclotron, and the creep-rupture tests were performed at 650°C in air...

... Premature creep-rupture swelling of AISI 321 austenitic stainless steel superheater tubes resulted in failures in the middle 1950s and promoted an extensive investigation. These failures in large utility boilers operating at pressures above 1500 psi and temperatures above 1000 F seriously...
