Hardness and tensile tests were conducted to study the variations in hardness and the mechanical properties of 6056 aluminum alloy under different aging processes. In addition, the types and sequences of precipitates in the alloy during optimal aging were observed using transmission electron microscopy (TEM), three-dimensional atom probe (3DAP), and differential scanning calorimetry (DSC). The results show that a lot of second phase particles, composed of spherical, short rod and irregular plate and strip, are distributed within the matrix of 6056 alloy wires. Under the optimal aging process (540 °C for 1 h solid solution followed by aging at 180 °C for 4 h), the 6056 aluminum alloy reaches a hardness of 136 HB and a tensile strength of 415.5 MPa. The main precipitates in the alloy matrix are identified as short rod-shaped β′′ phases, plate-shaped Q′ phases and spherical Guinier–Preston (GP) zones. The transformation of GP zones into β′′ phases and subsequently into Q′ phases occurs gradually by altering the ratio of Al, Mg, Si, and Cu during aging. The content of Cu atoms increases progressively during the growth of the precipitates, and the precipitation sequence is GP zones → β′′ phases → Q′ phases → Q phases.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"6 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188190","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}

At room temperature, AZ31B was stretched by 10% in the RD, TD, and 45° directions, with strain-hardening exponent calculations showing uniform stress levels. The hardening exponent decreases with increasing strain rate, and dislocation density rises in the RD direction. Prismatic slip is the primary deformation mode, based on Schmid factor calculations. Tests along the RD direction at 100, 150, and 200 °C with a 0.01 s−1 strain rate reveal stress reduction with rising temperature due to a balance between hardening and softening mechanisms. The hardening exponent increases with temperature, indicating strong hardening potential in the AZ31B sheet. EBSD analysis at 100 °C shows a double peak in the polar plot (0002), suggesting pyramidal < c + a > slip as the deformation mechanism. At higher temperatures, dynamic recovery dominates, while grain growth prevails at 200 °C due to insufficient strain for dynamic recrystallization.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"2010 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188428","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}

There is scope to study the energy absorption characteristics of AMSFs at varying strain rates. Comprehending these characteristics is essential for effectively using these materials in many industrial applications. This study fills the gap by employing a novel method, such as hot compaction, to achieve density close to theoretical calculations. The impact of ceramic particles and volume fraction on AMSFs is studied under uniaxial compression loading at varying strain rates (1-2700 s−1). Also, deformation responses of AMSFs were observed using high-speed imaging for high-strain rate (HRS) tests. The stress–strain response indicates a positive shift in strain during dynamic loading and the maximum energy absorption properties achieved up to 72.34 and 78.92% for low- and high-strain rates, respectively. Further, the matrix failure is contributing to the hardening and deformation behavior at high-strain rates, offering valuable insights into the AMSF performance under different loading situations.","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"60 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142188467","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}

Current and pulse on-time were altered during EDC to investigate their effects on the responses such as material transfer rate (MTR), tool wear rate (TWR) and surface roughness (Ra). A single index named overall evaluation criteria (OEC) was formulated to optimize the process parameters for higher MTR, TWR and lower Ra.

Confirmation test was conducted at optimum condition of OEC, which resulted in 0.82% deviation in the experimental and predicted results.

The topography of the coatings, characterized by SEM, revealed the presence of globules, craters, cracks and redeposition layers.

To this end, this paper focuses on the microstructure evolution and deformation behavior under non-equilibrium forging conditions. Two types of experiments were performed for the Ti-55531 alloy with an original equiaxed structure: (1) static cooling and (2) concurrent deformation/cooling. In static cooling, the formation mode of αs phase is via αp/β phase interface instability or sympathetic nucleation, which is determined by the deviation degree of Burgers orientation relationship (BOR) of αp and β phases. In the near-isothermal deformation, formed low-angle boundaries and high-angle boundaries increase the available nucleation locations and cause the loss of BOR, which contribute to the morphology change for αs phase and accelerated phase transformation kinetics of β to αs. The bi-modal microstructure, including αp phase and fine-equiaxed or rodlike αs phase, respectively, is produced by a cooperation between dynamic precipitation of αs phase and DRX and DRV of β phase. Moreover, the texture intensity of α phase is weakened, and flow stress is reduced by 30% compared to that in the isothermal deformation, due to a delay in α phase precipitation, and grain-boundary sliding at αs–β interfaces.

Moreover, after approving the method of simulation, using this method, the powder cool-down process under natural convection from around the construction temperature (170 °C) to a temperature close to the ambient temperature (27 °C) is simulated by considering both the powder and the ambient gas for four different gases (air, nitrogen, argon, and helium) aiming to assess the heat transfer coefficient for each of the scenarios.

The results show that the penetration depth can increase by 40.1% and 21% with the addition of 5% hydrogen gas (H2) and 50% helium gas (He), respectively, to the pure Ar shielding gas. Both hydrogen and helium can improve the heat input, thereby increasing the penetration depth. However, compared with helium, hydrogen can greatly promote the arc contraction and increase the energy density, thus improving the penetration depth. Therefore, hydrogen can improve penetration more significantly. The microstructure of thin-wall samples fabricated by wire arc additive manufacturing is dominated by coarse columnar dendrites, and there are both eutectic M6C carbides and nano-scale M2C carbides.
