Increase of hardness of an alloy with an increase in time is known as ________

Increase of hardness of an alloy with an increase in time is known as ________ Correct Answer Age hardening

The strengthening of an alloy resulting from the precipitation of a finely dispersed second phase from a supersaturated solid solution is called age hardening. The finely dispersed second phase precipitates with age. This type of hardening is known as age hardening.
