High temperature environmental stress corrosion cracking of Nickel superalloys
23 March 2021
Hosted by Institute of Materials, Minerals and Mining.
The aim of this webinar is to explain the rationale behind the use and modification of a simple test method to assess stress corrosion cracking of single crystal Nickel based superalloys at temperatures ranging from 400-600°C. The webinar covers key elements of test specimen design, its implementation, and inspection methods used to characterise these materials when under constant loads in corrosive environments.
Preliminary results are presented comparing the effect of different salt compositions on the degradation and cracking of single crystal Nickel based superalloys. An overview is given of the inspection techniques used to quantify degradation after various times at elevated temperatures.
The webinar provides an overview of some of the key benefits and outputs from initial testing carried out so far. The research described provides a platform for the many outstanding questions to be considered and potential mechanistic theories debated.
