2019’s Plenary Lecturer, Digby D. Macdonald, kicked off Tuesday. Macdonald presented to a packed house about the initiation of pitting corrosion and the capabilities to accurately predict passivity breakdown.
Macdonald focused on aluminum-lithium (Al-Li) alloys, commonly used in the aerospace industry to help with light weighting. He guided the audience through the formation of blisters on the surface of alloys, and the seven reactions that occur according to the Point Defect Model. He discussed how we can predict the distribution of breakdown on the surface of the alloys.
Macdonald commented that many of the pits will “die,” comparing the lifecycle of humans and pits when they are in direct competition for resources with others close by.He noted that cracks nucleate at dead pits and discussed the influence of other compounds on the breakdown potential.
Macdonald concluded by stating that no only can we predict passivity breakdown locally,we have the tools to do it accurately.
NACE International’s third annual NACECares’ Volunteer Day takes place tomorrow, Sunday March 24, from 8 a.m. to 5 p.m. Dozens of volunteers will be building and donating bikes to benefit the Boys and Girls Clubs of Middle Tennessee at the Nashville Music City Center.Sign up during conference registration for a slot to join this exciting event!
The city of Nashville,known as the “Country Music Capital of the World,” has a diverse and deeply-rooted history that began well before its official founding on Christmas Eve 1779. From its bustling music scene, southern hospitality, and eclectic food, Nashville welcomes over 15 million visitors a year and is home to some of the nation’s most recognizable landmarks.
On Monday morning, NACE International hosted the interactive forum, Bridging the Gap with Effective Leadership, where attendees learned from a variety of experts in the fields of knowledge retention, knowledge transfer,and leadership best practices.
