Though, guidelines related to permeability measurement techniques have been established for twenty years, the permeability measurement device is not available in most investment casting foundries. This can lead to issues when establishing foundries to supply investment castings for high-value segments. A specific permeability measurement device has been developed by following guidelines published by a globally accepted standard body that further has been facilitated with the fundamentals of the Internet of Things. Different mold materials (using zirconium sand, aluminum silicate and fused silica) that are used in shell mold making for high-valued segments have been tested for establishing benchmark values of permeability. These values of permeability were observed in the range of 8 × 10-11–37 × 10-11 cm2 to achieve better quality shells as well as investment castings.","PeriodicalId":14231,"journal":{"name":"International Journal of Metalcasting","volume":"22 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142182401","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}

For this purpose, EN AC 44100 and EN AC 44100 + 10 wt%Zn alloys were fabricated by permanent mold casting. The microstructural examinations were performed using standard metallographic techniques. The phases in microstructures were identified by energy dispersive spectroscopy and X-ray diffraction analyses. The yield strength, ultimate tensile strength, and elongation to fracture of the alloys were determined by tensile testing after measuring their Brinell hardness. The tribological properties of the alloys were examined using a ball-on-disk type wear test apparatus. It was observed that the microstructure of the EN AC 44100 alloy consists of aluminum-rich α, primary silicon and β (Al–Fe–Si) phases together with the eutectic Si particles. The addition of zinc resulted in a significant increase in the hardness and the strength of EN AC 44100 alloy but a considerable decrease in its friction coefficient and wear volume by modifying the microstructure of it. The modification caused a reduction in the size of α grains and eutectic silicon particles. Effects of zinc addition on the mechanical and wear properties of the EN AC 44100 alloy were discussed in terms of the observed microstructural changes.","PeriodicalId":14231,"journal":{"name":"International Journal of Metalcasting","volume":"33 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142182489","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}

In this study, a short-spacing multi-source ultrasonic vibration (MUV) technique, specifically quad-source ultrasonic vibration (QUV), was introduced to prepare SiCp/A356 composites with a high weight fraction of 15wt.% SiC particles. The characteristic of acoustic streaming and the dispersion of particles were systematically investigated through numerical simulations and physical experiments. The results reveal that QUV mitigates acoustic attenuation and expands the potential cavitation region (exceeding the cavitation threshold of 1.1 MPa) compared to single-source ultrasonic vibration (SUV). The synergistic effect of multiple ultrasonic waves not only elevates cavitation intensity but also enriches the structures of acoustic streaming, significantly reducing agglomeration and improving the dispersion of SiC particles within the Al matrix. Without ultrasonic treatment, only a small proportion of SiC particles are embedded in the Al matrix, with an SSiC/St ratio of merely 2.23%. However, as the number of ultrasonic sources increases, the agglomeration of SiC particles was relieved, and the resultant holes diminish. Remarkably, under QUV treatment, the holes in the composites virtually disappear, and the SSiC/St ratio increases to 9.82%. Additionally, the composites exhibit superior mechanical properties, with a tensile strength of 200 MPa and an elongation of 7.0%, which are 10.5% and 38.5% higher than those achieved using SUV, respectively.","PeriodicalId":14231,"journal":{"name":"International Journal of Metalcasting","volume":"95 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141939888","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 investigation is focused on incorporating zirconium (Zr) as a primary alloying element, alongside nickel (Ni) and manganese (Mn), to assess their suitability for automotive engine applications. In Mn-containing alloys, tensile strength improvement was observed due to the precipitation of compacted α-Al15(Fe, Mn)3Si2 and Al6Mn phases. Meanwhile, Ni-bearing phases such as Al3CuNi and Al3Ni in Ni-containing alloys were found to inhibit crack propagation, thereby enhancing tensile properties. Results indicated that the addition of 0.75 wt.% Mn yielded comparable strength values to alloys containing 2–4 wt.% Ni at ambient temperature. Additionally, the presence of 0.25% Zr facilitated the precipitation of fine metastable L12-Al3Zr particles, contributing to improved alloy strength. However, the introduction of 4% Ni resulted in the formation of Al–Cu–Ni particles rather than Al2Cu, leading to a decrease in alloy strength upon aging.","PeriodicalId":14231,"journal":{"name":"International Journal of Metalcasting","volume":"375 1","pages":""},"PeriodicalIF":2.6,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141969140","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 resulting Elektron 21/HEA surface composites (SCs) processed through casting followed by FSP were compared to the cast followed by FSPed Elektron 21 alloy, exhibiting significant enhancements in mechanical properties and wear resistance. The surface of the Elektron 21 matrix, which underwent casting followed by FSP, showed a homogeneous dispersion of HEA particles. These particles served as precipitates, creating geometrically necessary dislocations that hindered movement under applied force. The bonding between the HEA and the Elektron 21 alloy at the interface was excellent, and differential thermal contraction resulted in a strain misfit. Consequently, the microhardness, yield stress, and ultimate tensile stress of the FSPed Elektron 21/HEA SCs improved by 38%, 37%, and 32%, respectively, compared to the FSPed Elektron 21 alloy, although ductility decreased by 33%. Furthermore, the FSPed Elektron 21/HEA SCs showed a 33% enhancement in wear resistance and a 27% reduction in frictional force generation compared to the FSPed Elektron 21 alloy. The worn surfaces of the FSPed specimens showed that the FSPed Elektron 21 alloy revealed deep grooves, pits, micro-cutting, micro-grooving, and ploughing, while these features were absent in the FSPed Elektron 21/HEA SCs.

A wide array of sand, aggregate, and binder combinations is commercially available. Utilizing these types of refractory materials in the casting process presents both technical and economic benefits and drawbacks. For intricate cast components, foundry technologists must assess the thermophysical properties of the mold material systems. With this knowledge, specialized high-performance material combinations may be employed in specific areas of the mold, while more economically viable systems are used for shaping the external mold support. This study primarily focuses on determining the heat capacity and thermal diffusivity and consequently the thermal conductivity using a specially developed analytical method. It investigates three different fundamental aggregates: silica, cerabeads®, and chromite. The result’s range provides an overview of relevant characteristics for the selected material systems. Given that the properties of sand affect heat flow during casting and solidification, these newly determined values can be utilized in future simulations.
