Implication

Analysis highlights the inadequacy of the soft denuded zone model in explaining stress relaxation cracking.

Key Points

The study concludes that the soft denuded zone model does not accurately explain stress relaxation cracking.
Evidence from literature demonstrates that the stress state near SRC locations refutes the model's predictions.
Critical examination of the model reveals discrepancies with real-world failure cases in high-temperature alloys.
A new SRC mechanism model will be introduced in a companion paper, backed by empirical data and observations.
