The microstructure evolution and dynamic precipitation for age-hardened AA 6082 alloy via cryogenic HCAP were investigated using electron backscattered diffraction and differential scanning calorimetry experiments based on the steady experimental temperature. The serrated shear mechanism was introduced to reveal the increase of high-angle grain boundaries and the formation of fine equiaxed grains at cryogenic HCAP. Moreover, the additional nucleating spots and the energy for precipitation were brought by severe plastic deformation, that promoted the dynamic precipitation of Guinier–Preston (GP) zones and partial β″ phase, while the precipitation of β″ phase is suppressed by cryogenic temperatures. Consequently, the comprehensive effects of HCAP and cryogenic temperature yielded refined and equiaxed grains, promoting GP zones and partial β″ phase dynamic precipitation. Compared to those specimens without HCAP, there were less dynamic precipitation on β′ and β phase in the HCAPed ones after heating because the early dynamic precipitation phases have occupied the nucleating spots, requiring higher peak temperatures and more activation energy than were available.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 4","pages":"1137 - 1151"},"PeriodicalIF":3.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The alloy exhibits an N-type raft structure under varying creep times, with a mismatch between the γ and γ’ phases ranging from − 0.06% to − 0.59%. A significant amount of secondary γ’ precipitates, predominantly spherical or cubic in shape, is dispersed in the matrix, with sizes decreasing gradually from the center of the γ matrix channel to the γ/γ’ interface, and randomly distributed in the matrix channels. Dislocations are discretely distributed in the γ matrix channel, which, upon encountering the secondary γ’ precipitates, impedes their movement, leading to the transformation of the initially dense dislocation network into an irregular one. Moreover, numerous small secondary γ’ precipitates particles can absorb dislocations. Approximately every 170 to 1628 atomic spacings of the secondary γ’ precipitates can accommodate a misfit caused by an edge dislocation.

Two porosity levels of Ti/Al interpenetrating phase composites (IPCs) were fabricated by infiltrating ZL102-Al melt into additive-manufactured TC4-Ti scaffolds with the TPMS porous in this study. The combination of the two-phase alloys exhibits structural integrity at the interfacial region, as evidenced by microscopic surfaces observed in uncompressed IPCs. Quasi-static compression tests were performed to demonstrate that the Young’s modulus, yield stress and maximum compressive stress of IPCs exhibit significant enhancement when compared to the individual TPMS scaffolds, due to the supporting and strengthening effect of the filling phase. In the compression process of IPCs, defects emerge initially at the interface between the ZL102 phase and TC4 phase, triggering the fracture and slip of the ZL102 phase, eventually propagating to involve fracture in the TC4 phase. The deformation behaviours obtained from numerical simulation were combined to support these experimental phenomena. The results show that the corresponding stress concentration region is the central region of the spiral surface, the maximum stress concentration region of the ZL102 phase is the same as that of the TC4 phase, and the ZL102 phase effectively shares part of the loading. The Ti/Al IPCs achieve equivalent load-bearing capacity through a simplified interpenetration process and the utilisation of lighter materials.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"31 4","pages":"955 - 970"},"PeriodicalIF":3.3,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668185","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the cold pilgering, the tube developed distinct microstructural and textural features at different positions (with varying internal/external diameters and wall thicknesses) due to their specific stress states and deformation amount. Microstructural and textural evolution during cold pilgering were analyzed by characterizing specimens (S0-S4) cut from typical tube positions mainly using electron channeling contrast imaging and electron backscatter diffraction techniques. Transmission electron microscopy was also utilized to reveal typical precipitates in the un-pilgered specimen (S0). Results indicate that at low/medium strains, there exist non-deformation grains with hard orientations in the pilgered tube specimens, leading to heterogeneous microstructures. With increasing strains, the tube specimens show continuously reduced grain sizes and increased kernel average misorientations along with higher fractions of low angle boundaries, resulting in enhanced microstructural homogeneity.
