“…In the study, the axial fatigue strength of the repeated welding joints was largely affected by the microstructure and radius of the weld toe [9]. The controversial explanation of the relationship between the microstructure and mechanical properties could have resulted from the instability in manual welding and the very narrow region of the HAZ in the repeated welding joints [10].…”

“…Many studies have shown that the degradation in strength and toughness always happens in HAZ. The Gleeble weld-simulator has been successfully employed to accurately control the thermal cycles and heat input to easily generate an available HAZ for the evaluation of the microstructure and mechanical properties [10][11][12]. Hsieh et al [13] used Gleeble to precisely control the cooling time of the HAZ, and studied the effects of different cooling time on the microstructure of 22% Cr duplex stainless steel.…”

Heat-affected zone (HAZ) of welding joints critical to the equipment safety service are commonly repeatedly welded in industries. Thus, the effects of repeated welding up to six times on the microstructure and mechanical properties of HAZ for AISI 304N austenitic stainless steel specimens were investigated by a Gleeble simulator. The temperature field of HAZ was measured by in situ thermocouples. The as-welded and one to five times repeated welding were assigned as-welded (AW) and repeated welding 1–5 times (RW1–RW5), respectively. The austenitic matrices with the δ-ferrite were observed in all specimens by the metallography. The δ-ferrite content was also determined using magnetic and metallography methods. The δ-ferrite had a lathy structure with a content of 0.69–3.13 vol.%. The austenitic grains were equiaxial with an average size of 41.4–47.3 μm. The ultimate tensile strength (UTS) and yield strength (YS) mainly depended on the δ-ferrite content; otherwise, the impact energy mainly depended on both the austenitic grain size and the δ-ferrite content. The UTS of the RW1–RW3 specimens was above 550 MPa following the American Society of Mechanical Engineers (ASME) standard. The impact energy of all specimens was higher than that in ASME standard at about 56 J. The repeated welding up to three times could still meet the requirements for strength and toughness of welding specifications.

“…At an LMP value of 28,000, the aged specimen resisted load bearing better than the AS and SO specimens. This was because the aged specimens had more γ'-Ni3 (Al, Ti) precipitate, which resulted in high temperature strength and creep strength [12][13].…”

Abstract. An accelerated creep test was implemented to study the effects of heat treatment on the creep properties of INCONEL 617. Three heat treatment conditions were set on the test specimens, including 1) as-received, 2) aged as the simulation of service conditions at 650°C for 1,000 h and 3) solutionised. The accelerated creep test was performed at 700, 750, 800 and 900°C with applied stress at 80% and 90% of the yield stress (YS) at tested temperatures. The results were analysed for both time to rupture and % RA, which showed that there was a significant drop in time to rupture and % RA at 750°C. Subsequently, the % RA increased while the time to rupture gradually decreased. The Larson Miller curve for all heat treatment conditions could be plotted with an interest in the presence of an intersection zone. This indicated the possibility of failure behaviour changes from a creep mode to an overload mode at low applied loads to high applied loads, respectively.
