one of the following is a step for the procedureof precipitation hardening or age hardening?

Question

Quizplus · Accepted Answer

Precipitation hardening, also known as age hardening, involves several steps to improve the hardness and strength of certain metals and alloys. These steps include solution treatment, where the alloy is heated to dissolve solute elements; quenching, where the alloy is rapidly cooled to create a supersaturated solid solution; and aging, where the material is reheated at a lower temperature to precipitate out the solute elements in a controlled manner, thereby increasing its hardness and strength.
