Zener–Hollomon parameter

The Zener–Hollomon parameter is used to help describe high temperature creep strain of a material such as steel.[1]

The Zener–Hollomon parameter is also known as the temperature compensated strain rate.

It is given by

${\displaystyle Z=\epsilon \exp(Q/RT)}$,

where ${\textstyle \epsilon }$ is the strain rate, Q is the activation energy, R is the gas constant, T is the temperature.

It is named after Clarence Zener and John Herbert Hollomon, Jr.
