The Larson-Miller parameter is a parameter used to estimate the time to failure of a material under creep conditions. It is calculated by multiplying the temperature in degrees Celsius by the logarithm of the time to failure in hours. The parameter is named after two engineers, F. R. Larson and J. Miller, who developed it in 1952. The Larson-Miller parameter is a useful tool for predicting the creep behavior of materials and can be used in a variety of applications, such as design of high-temperature components and predicting the remaining life of aging structures.
