【 摘 要 】

This letter explores issues surrounding region splitting, a current technique used to improve creep life predictions. The history of the technique is discussed briefly and its current implementation by major research groups described in more detail. An example of novel or non-traditional region splitting is also explored with its first known application to nano-creep. The issues surrounding region splitting when considered as an industry practice are also briefly discussed. The purpose of this letter is to explicitly discuss region splitting as a creep lifing technique and identify the current and future issues researchers and industry may face when implementing this powerful technique.
