Dispersed BCC structure Cr precipitates yield a strength of 512.0 MPa and elongation of 17.2%.
Aging temperature increases affect the stability and size of Cr precipitated phases, growing from 5.0 nm to 16.7 nm.
Secondary aging and cold rolling significantly enhance alloy properties, demonstrating the role of precipitation strengthening mechanisms.
Aging parameters impact microstructural characteristics, linking them to strength and conductivity outcomes in the alloy.
