As an implementation tool of data intensive scientific research methods, machine learning (ML) can effectively shorten the research and development (R&D) cycle of new materials by half or even more. ML shows great potential in the combination with other scientific research technologies, especially in the processing and classification of large amounts of material data from theoretical calculation and experimental characterization. It is very important to systematically understand the research ideas of material informatics to accelerate the exploration of new materials. Here, we provide a comprehensive introduction to the most commonly used ML modeling methods in material informatics with classic cases. Then, we review the latest progresses of prediction models, which focus on new processing–structure–properties–performance (PSPP) relationships in some popular material systems, such as perovskites, catalysts, alloys, two‐dimensional materials, and polymers. In addition, we summarize the recent pioneering researches in innovation of material research technology, such as inverse design, ML interatomic potentials, and microtopography characterization assistance, as new research directions of material informatics. Finally, we comprehensively provide the most significant challenges and outlooks related to the future innovation and development in the field of material informatics. This review provides a critical and concise appraisal for the applications of material informatics, and a systematic and coherent guidance for material scientists to choose modeling methods based on required materials and technologies.

“…Aluminum alloys may not meet these requirements because their strength is relatively low. [2,11,12] However, it's important to note that while equal channel angular pressing provides a significant advantage by enhancing the strength and ductility of metal materials, it comes with the drawback of being a relatively intricate and time-consuming processing method. [13] Aluminum alloys can be subjected to high temperatures, treatments, and loaded with relatively high stress levels.…”

Aluminum‐lithium alloy, being the lightest aluminum‐based alloy, holds significant potential for applications in the aerospace and military sectors. Currently, alloying treatment stands as a crucial method for enhancing the comprehensive performance of aluminum‐lithium alloy. This paper provides an overview of the production process of aluminum‐lithium alloys, encompassing smelting and deformation processing characteristics. Additionally, it outlines the developmental history of the chemical composition for the primary grades of aluminum‐lithium alloy, detailing the copper (Cu) and lithium (Li) content of the main alloying elements. And discusses the influence of various microalloying elements on the alloy’s properties.Additionally, it summarizes the structure, properties, and precipitation morphology of the three primary strengthening phases formed by the alloying of aluminum‐lithium alloys: T1 (Al2CuLi), θ′ (Al2Cu), and δ′ (Al3Li). The analysis also examines the impact of anisotropy on the mechanical properties of the primary dispersion. Finally, the paper addresses the challenges involved in alloying aluminum‐lithium alloys and proposes key research directions for element composition design.This article is protected by copyright.

“…Some of the earlier studies concluded that the strength of the joints can be improved by employing a pin length exceeding 40% of the lower layer thickness [13,14]. This process of FSAM has been studied by various researchers for fabricating multi-layered components of WE43 Mg alloy [15], 7075 Al alloy [16], Al-Zn-Mg alloy [17], 2195-T8 Al-Li alloy [18], AZ31 Mg alloy [19], and 2060 Al-Li alloy [20]. The frictional heat generated during the process leads to the softening of the processed zone; with coarsening and dissolution of the precipitates, resulting in deterioration in the strength of the FSAM build.…”

Friction stir additive manufacturing was employed to fabricate a SiC-reinforced AA6061 composite. The tool with a pin length of 4.5 mm (plunge depth of 50% into the lower layer thickness) was used for the experiment. The stir zone consisted of fine, equiaxed grains due to dynamic recrystallisation. Variations in grain size, as well as changes in precipitate distribution, size, and morphology, were detected along the build direction. Hardness and tensile strength varied across layers, with the top slice having the greatest values of 104.2 HV and 268.4 MPa, respectively. Notably, the FSAM build demonstrated improved ductility with a maximum of 58.98%, mostly ascribed to fragmentation and partial loss of grain-boundary phases, as well as strong interfaces that delayed necking.
