“…On the other hand, basing on the Hall–Petch relationship, the refinement in grains improves the mechanical properties of metals. ,, As mentioned above, Zn-CNTs@Ag have finer and more uniform crystal grains than Zn-CNTs (Figure ), which is also considered to enhance the mechanical properties. Similarly, Nai et al .…”

Zinc shows promise for bone repair applications, while its strength and ductility require to be improved. Carbon nanotubes (CNTs) are exceptional reinforcements due to their superior strength, ultrahigh Young’s modulus, and large aspect ratio. However, their strong agglomeration and weak interfacial bonding with the matrix are key bottleneck problems restricting the reinforcing effect. In this study, Ag nanoparticles were in situ reduced on CNTs and then the CNT@Ag powders were used to prepare Zn-CNT@Ag implants by laser powder bed fusion. Results showed that Ag reacted with Zn to form a “knot”-like AgZn3 phase. It had the same lattice structure (HCP) with Zn, which indicated a good lattice matching with the matrix, thus improving the dispersion of CNTs. More significantly, the knot played a “rivet” role and enhanced the load transfer capacity, which advantaged the CNT strengthening effects by assisting in transferring the load. Moreover, it enhanced the heterogeneous nucleation effects during solidification, which weakened the texture strength of the matrix and thus increased the ductility by improving the sliding capacity. The compressive yield strength, ultimate tensile strength, and elongation of the Zn-CNT@Ag implant were increased by 22, 26, and 17% in comparison to Zn-CNTs. Moreover, the Zn-CNT@Ag implant exhibited favorable antibacterial activity with a bacterial inhibition rate of 87.79%. Additionally, it also exhibited a suitable degradation rate and acceptable biocompatibility.

“…The grain growth in the (0001) orientation is further weakened, while the grain growth in (21̅ 1̅ 0) and (101̅ 0) orientations is persistently enhanced. 32 In other words, the texture intensity of Zn-CNTs@Ag was weakened compared with Zn-CNTs.…”

“…Especially, when the mean value of index data is not 0, the Gini coefficient is calculated by the improved formula (14). When the mean value of the index data is 0, the Gini Discrete Dynamics in Nature and Society coefficient of the index is calculated by the original formula (15). e Gini coefficient of the index truly reflects the data changes of different evaluation objects of the index.…”

The identification and evaluation of important parts play an important role in effective production arrangement and shortening the product development in the product design stage. In this paper, a complex product node importance evaluation method based on multilayer network is proposed to identify and evaluate importance parts faster. First, a complex product design expression network based on “function behavior structure (FBS)” multilayer complex network is established. Second, the evaluation index system of important design parts for complex products based on multilayer network is constructed. Third, a three-parameter grey relational model based on the fuzzy analytic hierarchy process and the Gini coefficient method is proposed. Finally, this method is available and feasible through taking the large permanent magnet synchronous centrifugal unit as an example.

“…The way a change propagates or gets absorbed depends on margins in a designed system, which can buffer such changes (Long and Ferguson 2019;Li et al 2021a;Brahma and Wynn 2021). The way designers allocate margin, therefore, has the capability to influence change propagation (Eckert et al 2004).…”

Interest in change propagation analysis for engineering design has increased rapidly since the topic gained prominence in the late 1990s. Although there are now many approaches and models, there is a smaller number of underlying key concepts. This article contributes a literature review and organising framework that summarises and relates these key concepts. Approaches that have been taken to address each key concept are collected and discussed. A visual analysis of the literature is presented to uncover some trends and gaps. The article thereby provides a thematic analysis of state-of-the-art in design change propagation analysis, and highlights opportunities for further work.
