Abstract

In this paper determination of an interface damage function (IDF), from a stereological procedure similar to that presented by Hillard is described. The mathematical and experimental simplicity of the method is utilized in measuring an IDF for polycrystalline copper crept at 0.6T{sub m} under uniaxial tension. Whereas previous work focussed on a five parameter description of the local state of a grain boundary, the domain of the IDF is increased to eight degrees of freedom in the present study to include the complete geometrical description of grain boundary structure. The resulting functions identify certain types of grain boundaries which were preferentially damaged. Most of the damage occurred on interfaces oriented nearly normal to the principal stress axis. Some relatively small angle boundaries demonstrated a surprising propensity to cavitate as did certain special boundaries distinguished by a group multiplicity in misorientation space greater than one. A sequence of two dimensional projections through the eight-dimensional domain of the IDF is shown to identify a number of interface structures which are readily damaged.

(Microstructural dependence of the cavitation damage function in the FCC materials: Annual report, 1990--1991)

Technical Report

The interface damage function (IDF) defines an area fraction of damage on crystallite interfaces. This function, which is material and condition dependent, sustains a complete geometrical description of grain boundaries and identifies those types of interfaces which are preferentially damaged. Included in the IDF is functional dependence, not only upon lattice orientations or misorientations, but also upon grain boundary normal; this dependence has been largely neglected in other studies examining damage inhomogeneity of polycrystals. The experimental method used in describing the damaged microstructures included random sectioning of the damaged specimen, and the manual or semi-automatic construction of grain maps describingmore »« less

Evidence of grain-boundary-sliding-induced cavitation in ceramics under compression

Journal Article Blanchard, C; Chan, K - Journal of the American Ceramic Society; (United States)

Detailed microscopy of two crept aluminas, one with (AD99) and one without (Lucalox) a grain boundary glassy phase, has been performed to determine the pertinent damage mechanisms during creep. Evidence is presented for a nucleation-controlled cavitation process where creep cavities nucleate primarily on two-grain facets, followed by cavity growth and coalescence to form grain-facet-sized cavities and microcracks. A variety of creep cavity morphologies were observed in Lucalox, including spheroidal and irregularly shaped cavities. The latter finding implies a strong influence of crystallographic orientation and the corresponding surface energy of the cavitated planes on the cavity shaped. In contrast, classical spheroidalmore »« less

The inter-relationship between grain boundary sliding and cavitation during creep of polycrystalline copper

Journal Article Ayensu, A; Langdon, T - Metallurgical Transactions, A

High-temperature creep tests were conducted on polycrystalline copper of commercial purity in order to investigate the inter-relationship between the extent and the rate of grain boundary sliding (GBS) and the development of internal cavitation. An image processing technique was used to provide quantitative information on the size and shape of the cavities formed over a range of stresses and at temperatures from 673 to 873 K. The results demonstrate that cavity development is inhomogeneous within any specimen, such that there is an increase in the level of cavitation in regions of higher local strain. It is shown by quantitative measurementsmore »« less

Cavitation contributes substantially to tensile creep in silicon nitride

Journal Article Luecke, W; Wiederhorn, S; Hockey, B; ... - Journal of the American Ceramic Society

During tensile creep of a hot isostatically pressed (HIPed) silicon nitride, the volume fraction of cavities increases linearly with strain; these cavities produce nearly all of the measured strain. In contrast, compressive creep in the same stress and temperature range produces very little cavitation. A stress exponent that increases with stress ({dot {var_epsilon}} {proportional_to} {sigma}{sup n}, 2 < n < 7) characterizes the tensile creep response, while the compressive creep response exhibits a stress dependence of unity. Furthermore, under the same stress and temperature, the material creeps nearly 100 times faster in tension than in compression. Transmission electron microscopy (TEM)more »« less

Grain boundary inter-connections in polycrystalline aluminum with random orientation

Journal Article Wang, Weiguo; Cai, Changhui; Rohrer, Gregory; ... - Materials Characterization

Highlights: • The GBICs in a pure aluminum are not random, showing remarkable preference on the planes of low Miller index. • {1 1 1}/{1 1 1} is the most frequent GBIC in pure aluminum. • {1 1 1}/{1 1 1} GBIC is mainly coming from the GBs formed by rotations around , and axes. • {1 1 1}/{1 1 1} GBIC possesses higher PCSD and definite dislocation structures compared to the general GBs. • To pursue {1 1 1}/{1 1 1} GBIC is a pint-cut for the GBE research in high stacking fault energy FCC materials. - Abstract: Grainmore »« less
