For its reliable application in high-temperature environments, understanding its microstructural evolution and mechanical behavior under prolonged thermal exposure is crucial but remains underexplored. This study investigates the microstructural evolution and mechanical properties of laser powder bed fusion (LPBF) fabricated Ti₂AlC-modified IN718 during long-term thermal exposure at 760 °C. The results reveal that (Ti, Nb)C carbides formed from Ti₂AlC decomposition coarsened according to the Lifshitz-Slyozov-Wagner (LSW) model, while σ phases nucleated and grew along grain boundaries adjacent to carbides. The thermal stability of γ″ and γ′ in co-precipitates inhibited the transformation of metastable γ″ to δ phases, contributing to microstructural stability. Cellular structures were stabilized by the pinning effects of (Ti, Nb)C carbides, with boundaries covered by elongated γ″ phases during thermal exposure. This led to Nb depletion within sub-grains, limiting γ″ growth in co-precipitates and driving a stacking sequence evolution from γ″/γ′/γ″ to γ′/γ″/γ′. The coarsening of elongated γ″ precipitates triggered a transition in deformation mechanisms from dislocation shearing to micro-twinning. In regions where cellular structures were annihilated, γ′ and γ″ coarsened slowly, with some γ″/γ′/γ″ evolving into γ′/γ″ duplets, maintaining shearing as the dominant deformation mechanism. Tensile tests at 650 °C demonstrated a continuous decrease in yield strength (YS), primarily attributed to the coarsening of σ phases and the reduction in γ″/γ′/γ″ triplets. Conversely, ductility improved significantly from 9.6 % to 21.1 %, driven by the activation of micro-twinning and enhanced dislocation motion facilitated by coarsened precipitates. These findings highlight the importance of Ti₂AlC in stabilizing the microstructure and optimizing the high-temperature performance of IN718 alloys under prolonged thermal exposure.</div></div>","PeriodicalId":385,"journal":{"name":"Materials Science and Engineering: A","volume":"932 ","pages":"Article 148272"},"PeriodicalIF":6.1,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143759618","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To accurately predict the failure of metal foils during microforming processes, taking into account the size effect on the forming limit. This study constructed tension-compression forming limit diagrams (FLD) for TA1 pure titanium (Ti) foils at thicknesses of 0.08 mm, 0.1 mm, and 0.2 mm based on digital image correlation (DIC). Specifically, it implemented Holmberg uniaxial tensile testing, model prediction based on the modified Oyane ductile fracture criterion, and the fully connected neural network (FCNN). It is found that the forming limit of TA1 pure Ti foils increases with larger specimen thickness. For foils of the same thickness, the forming limit rises with the decrease in the ratio of specimen thickness to grain size (t/d). Additionally, as t/d increases, the influence of the strain rate sensitivity on the overall strain state of the material diminishes, creating similar strain states of specimens in different strain paths. By analyzing the FLD constructed in three methods, it is found that with the t/d and Hill48 yield criteria, the modified Oyane ductile fracture criterion effectively predicted the size effect.

The effects of different ultrasonic amplitudes on the solidification structure and mechanical properties of Al-Cu alloys were investigated. Results indicated that applying UV with 10 μm amplitude effectively suppresses metallurgical defects in the microstructure of as-built 2319 aluminum alloy and cleanses their inter-layer interfaces. Compared with the non-UV sample, under the action of UV with the amplitude of 10 μm, the grain size refinement reaches a maximum of 25 %. UV improves molten pool fluidity and reduces temperature gradients. However, UV with large amplitude can trigger excessive ultrasound heat effects and intense cavitation behavior, which is not conducive to improving the uniformity and refinement of the solidified microstructure.

The yield-asymmetry of the alloy in the extruded condition was found to be 1.08, increasing to about 1.22 after heat treatment. Annealing creates new texture components that are favorable for extension/contraction twinning. Additionally, the increase in average grain size after annealing increases the probability of extension twin formation. Increasing the twin probability and decreasing the slip-to-twin transfer critical stress enhances the difference between tensile and compressive yield strengths. Additionally, the mentioned phenomenon is the reason for the lower strength level, higher ductility, and higher yield asymmetry of the annealed specimens. Fraction of blocky-LPSO also diminished through annealing, giving way to the formation of lamellar-LPSO within α-grains. Under tensile loading, lamellar LPSO exhibits structural integrity, while under compression, yielding occurs through the formation of kink bands. The high susceptibility of lamellar LPSO for strain induced structural evolution rather than blocky ones, could justify the observed low yield-asymmetry of extruded microstructure.</div></div>","PeriodicalId":385,"journal":{"name":"Materials Science and Engineering: A","volume":"932 ","pages":"Article 148263"},"PeriodicalIF":6.1,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143746462","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
