The Effect of Aging Parameters on Properties of Maraging Steel

In this article, an investigation of aging parameter (temperature and time) effects on mechanical properties and dimensional changes of Maraging 15 10 5 steel is presented. Aging tests were carried out in a dilatometer accompanied by simultaneous registration of forthcoming alterations of size. The results indicate a significant influence of aging temperature and aging time duration on achieved hardness values, as well as on dimensional changes, which is caused by diffusion of alloyed elements from Ni-martensite matrix during aging. On the basis the tests, optimal aging temperature and aging time duration of Maraging 15 10 5 steel are determined.
