About This Conference

Overview:  Environmentally-assisted cracking, EAC, of engineering materials has been known for at least 50 years. The sensitivity of engineering alloys to environmental exposure is well known from an engineering perspective. What is not known with certainty at this stage is the mechanism by which the many manifestations of EAC occur. This understanding is fundamental to the development of strategies for control and predict failures of EAC is of great importance to the failure communities.

While significant progress in our understanding of EAC has been achieved in recent years, important fundamental questions like “how environment affects the crack driving force”, and “why do ordinarily ductile materials fail in a brittle manner when exposed to certain environments” remain unanswered.

Our objective is to congregate a group of “skilled in the field” researchers in metallic materials for a workshop style conference that will endeavor to help clarify our current understanding of EAC and identify approaches to improve the current semi-quantitative understanding of the mechanisms.

The emphasis of the presentations will be on:

•           Systematic evaluation of the governing parameters such as thresholds stress intensity factors, crack growth rates, steady state behavior, effects of yield stress, microstructure, and concentration of the aggressive environment (aqueous, gaseous, LME), and load-history on static/cyclic corrosion crack growth;

•           Papers including experimental data for crack initiation and/or growth and those exploring unifying principles governing these time-static/cyclic stress dependent crack growth phenomena are particularly welcome;

•           Analysis of crack tip microscopy, chemistry;

•           New techniques for measuring crack initiation in aqueous environment;

•           Emphasis is on understanding and quantifying rather than reporting the data of some material response;

•           All topics are to be at room temperature; no high temperature work is accepted

Scope:  The scope of symposium includes the fundamental understanding of EAC from the initiation stage to growth and final failure in engineering alloys.

Preliminary Technical Topics:

•           Systematic variation of threshold KIscc and steady state (da/dt) in aqueous and            gaseous environments

•           Role of internal/external hydrogen on threshold K and crack growth

•           Crack tip chemistry and microscopy

•           Modeling of the governing mechanisms-atomistic and continuum

General Information

Engineering Conferences International (ECI) is a not-for-profit, global engineering conferences program, originally established in 1962 that provides opportunities for the exploration of problems and issues of concern to engineers and scientists from many disciplines.

The format of the conference provides morning and late afternoon or evening sessions in which major presentations are made. Poster sessions will be scheduled for evening discussion as well. Available time is included during the afternoons for ad hoc meetings, informal discussions, and/or recreation. This format is designed to enhance rapport among participants and promote dialogue on the development of the meeting. We believe the conferences have been instrumental in generating ideas and disseminating information to a greater extent than is possible through more conventional forums.

All participants are expected both to attend the entire conference and to contribute actively to the discussions. The recording/photographing of lectures and presentations is forbidden. As ECI conferences take place in an informal atmosphere, casual clothing is the usual attire.
