artificial ageing below peak ageing temperature and time conditions, resulting in slightly reduced tensile strength and improved ductility, compared with peak aged metal (see: peak ageing), kunstlik vanandamine allpool tippvanandamise temperatuuri ja kestust, mille tulemusena saadakse veidi väiksem tõmbetugevus ja parem sitkus võrreldes tippvanandamisega (vt tippvanandus)
