You wish to replace the blade material with a material that will not creep as fast into the clearance gap as the current material. Which of the materials (A or B) should be selected based on their creep curves below and why? /

U wil die lemmateriaal vervang met 'n materiaal wat nie so vinnig in die gaping sal kruip as die huidige materiaal nie. Watter van die materiale (A of B) moet gekies word op grond van hul kruipkurwes hieronder en hoekom?
