The aging behavior of the 18Ni (350) maraging steel was investigated using high throughput nanoindentation technique. The samples were obtained after austenitizing at 830 ˚C and quenching in water followed by an aging process. The aging process was performed at 430 ˚C, 500 ˚C, and 570 ˚C for different aging time; from 30 second up to 5 hours. Utilizing spherical indentation technique, indentation elastic modulus (Eind), yield strength (Yind), and hardening rate (Hind) were measured using a 100 Ám radius spherical tip. Several indentation tests were carried out to provide statistical measurements on each sample. Spherical indentation stress-strain analysis technique confirms to be a reliable approach on mechanical property measurements of advanced steels from small coupons of materials in an efficient time.
