Abstract
17-4 precipitation hardened stainless steel (17-4PH SS) has been reported to have excellent mechanical properties and excellent corrosion resistance, and is one of the materials used and studied with the powder bed fusion (PBF) method. Powder bed fusion (PBF) is a new manufacturing technology that has recently attracted attention in.....

DOI:
https://doi.org/10.3365/KJMM.2019.57.1.10
Abstract
Cu-Ti alloys were strengthened by Cu4Ti intermetallic compound precipitation in a Cu matrix during aging. The Cu-3.5 wt% Ti(Cu-4.6 at% Ti) alloys without deformation and with uniform and non-uniform deformation were aged at 450 oC for various times after solution treatment at 885 oC. The uniformly and non-uniformly deformed alloys.....

DOI:
https://doi.org/10.3365/KJMM.2016.54.10.716
Abstract
nSUH660 is a precipitation hardening stainless steel which has high strength at moderately high temperature. In this study, the effect of a secondary aging-treatment after the standard 720 °C heat-treatment was investigated. The Rockwell C hardness test with detailed TEM observerations was performed to study the steel’s hardening mechanism. The.....
