Characterization of the Interfacial Zone Between a HIPed Fe-Based Alloy and a Stainless Steel Container

Effect of the microstructure on the tribological properties of HIPed and PTA-welded Fe-based hardfacing alloy

“…1 (a)) presents a fine-grained microstructure. XRD coupled with SEM-EDX analyses performed in previous studies [21][22] revealed that the matrix is primarily austenitic and only contains a small amount of ferrite. Small M 23 C 6 -type carbides (M = Cr, Mn, Mo) are homogeneously dispersed in the matrix: globular carbides in zones between the primary powder particles and lath-like interdendritic carbides inside the particles (see supplementary material S1).…”

“…The powder composition was reproduced in the nominal compositions of the HIP and PTAW hardfacings. The HIPed Norem02 samples were obtained by sintering at 1100 • C and 120 MPa for 3 h, after a 2 h heating and pressurizing ramp and natural cooling (process details are available in [22]). The Norem02 elaborated by PTAW was taken from an industrial pressurized water reactor (PWR) shutter for which precise process parameters are not of our knowledge.…”
