A metal is experiencing steady - state creep deformation at some rate, Es 1. If the temperature is doubled, what will be the ratio of the new steady - state creep rate to the initial - i. e., what is Es 2 / Es 1? You may consider all parameters other than temperature in the expression for secondary creep rate, &s, to be equal between ...
The turbine blade is subjected to high-temperature and high-stress conditions, leading to concerns about creep deformation. As an engineer, you are tasked with selecting an appropriate material for the blade from the following options:I. Material A: Nickel-based superalloy (High melting point, good creep resistance, moderate cost) II.
