Owing to restrictions on forming dimensions, laser powder bed fusion (LPBF) components will continue require welding in the future. The post-weld thermal cracking of LPBF-Haynes 230 superalloys has become a key issue hindering their assembly service. In this study, it was found that both continuous TCP phase and M5Si3 silicides near crack have large interface strain with matrix. Replacing C Si atoms B at reduces melting point carbides grain boundaries (GBs), thereby inducing solidification...
Abstract The initiation stage and short crack behaviour in torsional fatigue of a 0.4% C steel was investigated by replication technique. cracks initiated propagated the ferrite phase which is located at prior austenite grain boundaries form long allotriomorphs. At this development it proposed that growth rate depends on extent intensity plasticity tip crack. Crack per cycle correspondingly proportional to strength slip band. ferrite‐pearlite are strong barriers propagation, manifested...
The hot deformation behavior of Ni–Cr–Fe-based ChS57 alloy was investigated by isothermal compression tests in the temperature range 1000–1200 °C with strain rates covering 0.001–10 s−1. Based upon hyperbolic sine function and dynamic material model, constitutive model processing maps were established, microstructure evolution systematically analyzed optimization working window completed. results indicate that flow stress increases remarkably increasing rate decreasing temperature, while...
The evolution of tensile properties and microstructure in three 9% Cr martensitic rotor steel with varying contents W Mo elements is investigated after aging at 630 °C for different durations, a primary focus on the characteristics martensite laths blocks, grain boundaries, dislocations, precipitates. results indicate that presence not only influences precipitation coarsening behavior Laves phases but also M23C6 carbides, which differs from conventional beliefs. elevated content reduced...
The study investigated the creep-fatigue interaction behavior, fracture mechanism, and microstructure evolution of C630R ferritic/martensitic heat-resistant steel at 630 °C 1% strain amplitude. results indicate that exhibits noticeable cyclic softening with a decrease in ratio from 0.46 to 0.40 as loading time increases. Microstructure was examined using optical scanning electron microscopes, revealing appearance secondary cracks on longitudinal section sample. These exhibited curved...
