Zener–Hollomon parameter

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

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

It is given by

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

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.
