The age-hardening behavior of Fe−25.3Ni−1.7 Ti (wt pct) alloy both in undeformed specimens and in specimens cold deformed by 10 or 20 pct prior to aging was studied. The microstructural changes during aging were observed using transmission electron microscopy (TEM) and atom probe analysis and there were related to the mechanical properties as measured by microhardness and shear punch testing. A...

Slow strain rate tests on hydrogen-containing specimens of PH13–8Mo maraging stainless steel showed H-assisted subcritical quasi-cleavage cracking, accelerating material failure. Fractographic analysis revealed that is composed flat brittle areas and rougher areas. Electron backscatter diffraction (EBSD) was performed a secondary subcritically grown crack. High resolution EBSD significant cryst...

In this work, the effect of heating rate on phase transformation temperatures was investigated using dilatometry analysis. Continuous and isothermal holding above Ac3 temperature microstructural evolutions in additively manufactured (AM) parts Fe-Cr-Ni maraging stainless steel were studied. The features developed within processes characterized employing electron backscatter diffraction transmis...
