Large-sized grains show superior superelastic properties because the grain boundaries are minimized and the grain constraints caused by triple junctions are reduced.

In this paper, the effects of adding Cu on the subgrain characteristics during AGG and microstructural evolution of FeMnAlNi-based superelastic alloys were systematically investigated. The addition of Cu reduced the temperature at which the γ phase precipitates and altered the morphology of the γ phase. After the dissolution of the refined γ phases, the average subgrain size became smaller and misorientation increased. These characteristic subgrain changes improved the driving force for AGG and accelerated the grain boundary migration rate. Due to the addition of Cu, the maximum grain size reached 28.2 mm.

A comparative study has been carried out on microstructure and mechanical properties of the material processed through both routes to assess the efficacy of the powder metallurgical process as a viable alternative to the investment casting route. The HIPed material is free from deleterious prior particle boundaries and coarse primary γ′ and has finer grain size compared to cast material. The HIPed material exhibits higher strength and ductility at room temperature, whereas ductility of HIPed alloy at 760°C is less than for the cast alloy. Detailed microstructural analysis and thermodynamic calculation reveal that network of carbides at the grain boundary of HIPed material causes lower ductility although HIPed material exhibits better strength than cast material, even at higher temperature.

The formation mechanism, kinetics and structural characterization of NaAl11O17 were systemically studied based on the solid-state reaction in Na2CO3-Al2O3 system, and the reaction conditions that prevent the formation of NaAl11O17 were also established. The results show that NaAl11O17 is more feasible to form than NaAlO2 when the Al2O3-to-Na2O molar ratio (A/N) is > 11.0, and it almost completely transforms into NaAlO2 when the A/N ratio decreases to 1.0. The formation kinetics of NaAl11O17 corresponds to the diffusion-controlled model of a 3D Ginstling-Brounstein model in the temperature range of 1000–1200°C. The conversion efficiency of NaAl11O17 is controlled by the phase boundary reaction model. Furthermore, the apparent activation energy and corresponding kinetic equation of NaAl11O17 formation were determined to be 46.89 kJ/mol and k = 1 × exp[–46.89/RT], respectively. The crystal structure characterization reveals that NaAl11O17 is formed by the doping of Na+ into [AlO4] tetrahedron to form a solid solution.","PeriodicalId":605,"journal":{"name":"JOM","volume":"40 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141931134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, these models often do not consider the effect of the solid-phase growth style on the interaction between NPs and the liquid-solid interface, given that Al dendrites typically only exhibit a continuous growth style attributed to a non-faceted growth mechanism. Yet, what occurs when the solid phase exhibits different growth styles? In this work, the behaviors were found to be different when γ–Al2O3 NPs came across eutectic non-faceted Al2Cu or primary faceted Al2Cu in a hypereutectic Al-Cu alloy. Specifically, the NPs can be engulfed by eutectic Al2Cu but be pushed away by primary Al2Cu. It is supposed that the Jackson alpha factor should be considered when building theoretical models to predict the interactions between nanoparticles and liquid-solid interfaces.","PeriodicalId":605,"journal":{"name":"JOM","volume":"2 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141887024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
