Abstract

The effect of austenitization temperature, aging temperature, and, aging time on the development of precipitates in a novel maraging steel known as F1E was investigated. The investigation primarily employed small angle neutron scattering (SANS) coupled with thermal calculations, atom probe tomograph...
