Dr. Angelique Lasseigne is the CTO of G2MT and G2MT Laboratories. She has spent the last fifteen years providing metallurgical failure analysis and consulting across a variety of industries as well as developing the next generation of non-destructive sensors to measure through-thickness material properties. Dr. Lasseigne received her undergraduate degrees in Physics and Metallurgical and Materials Engineering from Centenary College of Louisiana and Colorado School of Mines in Golden, CO. She later earned her Master's and Ph.D. degrees in Metallurgical and Materials Engineering from Colorado School of Mines and the Federal Institute of Materials Research and Testing in Berlin, Germany. Angelique then completed an Academy of Science - National Research Council Post-Doctoral Fellowship at the National Institute of Standards and Technology in Boulder, CO where she continued to develop and test the capabilities of advanced non-destructive material property sensors. Angelique has published over 100 scientific papers and co-authored three books in the fields of welding metallurgy, corrosion, and non-destructive testing for materials characterization.
The number of graduates in metallurgical engineering has decreased dramatically in the past few decades (many schools have changed to materials science). The number of metallurgists in chemical plants has also continued to decrease, yet the infrastructure in chemical plants and is older than ever and failures are widespread. Further complicating matters are: (1) the loss of invaluable inside knowledge through retirement, and (2) the industry continues to push for higher throughput rates and more aggressive operating conditions, and (3) wider variance in quality of materials. Metals will continue to be the dominant material because polymers, ceramics, and nano-materials simply cannot compete (for example, in terms of strength to value ratio or temperature capability). G2MT will show why metallurgy is still a critical part of every chemical plant and why metallurgy knowledge is important to extend operating life and dramatically improve plant safety, while increasing value. Examples of failures that have occurred in chemical plants due to various metallurgical issues (during design, fabrication, and operation) will be presented along with recommendations on how to prevent failures.
There is no registration fee. The lunch menu ranges from $8 to $12, and the South Texas Section will subsidize lunches by $5 per attendee.STS members as well as non-members are welcome to attend. We only request that you pre-register at the STS-AIChE.org website so we can get an accurate head count for the restaurant.
