However, MMCs often face challenges such as agglomeration and inhomogeneous distribution of the reinforcing phase, leading to significant degradation of mechanical properties. In this study, we propose a method to overcome these obstacles by in-situ alloying via laser powder bed fusion (LPBF), achieving a uniform distribution of the reinforcing nano-sized phase (α-Al<sub>2</sub>O<sub>3</sub>) within a medium-entropy alloy matrix (CoCrNi). During the LPBF process, Al<sub>2</sub>O<sub>3</sub> is refined from the micrometer scale to the nanometer scale, simultaneously affecting the crystal orientation and leading to grain refinement of the CoCrNi matrix. The mechanical properties of CoCrNi were significantly enhanced by adding Al<sub>2</sub>O<sub>3</sub>, with an ultimate compressive strength of ∼1143 MPa, a fracture strain of ∼25%, and a hardness of ∼300 HV. The achieved strength and hardness levels are among the highest reported in the literature.

In this study, we investigate topological interface modes in I-WP (Wrapped Package) TPMS geometry. Inspired by a one-dimensional (1D) Su–Schrieffer–Heeger (SSH) model, we design 1D elastic Phononic Crystals (PCs) made of sheet-based I-WP minimal surface geometry. By manipulating the geometry of the I-WP minimal surface, we open the degeneracies formed at the edges of the Brillouin zone to create band-folding-induced bandgaps. We then design a 1D dimerized chain of two topologically distinct unit cells of I-WP minimal surface to create an interface and introduce topological interface modes. Numerical simulations are performed to study the band structure and topological transition properties of the proposed 1D PC. In addition, we show that hybridizing alternative I-WP unit cells of different relative densities can also break the inversion symmetry of the periodic structure in contrast to manipulating the geometry. The 1D PC made of hybridized I-WP geometry is then used to realize topological interface modes. The proposed 1D PCs are additively manufactured to experimentally validate the existence of topological interface modes. Our work provides an efficient method for TPMS structures to produce multifunctional devices that can support superior load-bearing capabilities as well as robust topological phase properties.</div></div>","PeriodicalId":383,"journal":{"name":"Materials & Design","volume":"252 ","pages":"Article 113749"},"PeriodicalIF":7.6,"publicationDate":"2025-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143509633","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HT method envisions the fabrication of small samples for rapid automated hardness and porosity characterization, and a smaller set of tensile specimens for more labor-intensive direct measurement of yield strength and ductility. The ML approach is based on a sequential application of Gaussian processes (GPs) where the correlations between process parameters and hardness/porosity are first learnt and subsequently adopted by the GPs that relate strength and ductility to process parameters. Finally, an optimization scheme is devised that leverages these GPs to identify the process parameters that maximize combinations of strength and ductility. By founding the learning on larger “easy-to-collect” and smaller “labor-intensive” data, we reduce the reliance on expensive characterization and enable exploration of a large processing space.
