以高性价比颗粒硅带为衬底多晶硅薄膜的二次引铝低温制备法

, 2003
本文报道了在廉价的颗粒硅带上用PECVD法并两次引入铝的工艺制备多晶硅薄膜。第一次引入铝是为了去除薄膜上过多的杂质；第二次引入铝是为了实现低温诱导结晶。通过对薄膜样品的拉曼谱和X射线衍射(XRD)谱分析，我们认为金属低温诱导结晶成功与否跟诱导前薄膜的结构密切相关。采用该工艺成功地制备了结晶度92％左右 ...

Liquid‐Induced Healing Enables High‐Performance Microlattice Metamaterials in Laser Powder Bed Fusion

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Laser powder bed fusion (LPBF) enables the fabrication of complex superalloy microlattice metamaterials, but internal defects and micro‐segregation severely impair their performance. While conventional hot isostatic pressing (HIP) is widely used for volumetric defect closure, maintaining geometric fidelity remains challenging for fine‐featured

Synergistic B/Si Microalloying Induced Wear Resistance Improvement in FeCoNiCrCu High‐Entropy Alloy Coatings Prepared by Annular Oscillating Laser Deposition

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT To address the insufficient wear resistance of high‐entropy alloy (HEA) coatings under extreme conditions, FeCoNiCrCu and FeCoNiCrCuB0.03Si0.03 microalloyed coatings were fabricated via annular oscillating laser deposition. This work systematically investigated the effects of synergistic B/Si addition on their phase composition, microstructure,

Oxygen Vacancy‐Engineered CoFeMo‐LDHs Enables Dual‐Reaction Pathway Synergistic Enhancement of Nanozyme Activity for Intelligent Colorimetric Sensing

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Defect engineering plays a crucial role in regulating the active sites and reaction pathways of nanozymes. In this work, oxygen vacancies (Vo) were successfully introduced and stably regulated in ternary CoFeMo layered double hydroxide (CFM LDHs) via a microwave‐assisted hydrothermal strategy, leading to the construction of oxygen‐vacancy‐rich

Synergistic Enhancement of Creep Performance in Al19Co21Fe20Ni40 Eutectic High‐Entropy Alloy by Coupling Heterostructure Design With Boron‐Assisted Interfacial Optimization

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT This study systematically investigates the creep behavior of an Al19Co21Fe20Ni40 eutectic high‐entropy alloy (EHEA) at 500°C, focusing on the synergistic effects of heterostructure design and trace boron doping. Thermomechanical processing was employed to produce a heterostructure consisting of alternating lamellar and equiaxed regions.

Achieving Strength–Ductility Synergy in a Near‐α Powder Metallurgy Titanium Alloy via Deformation‐Induced Nanoscale β Precipitation

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Powder metallurgy (PM) near‐α Ti alloys are often constrained by a pronounced strength–ductility trade‐off, due to the coarse lamellar microstructure formed during the sintering process. To address this issue, a thermomechanical route combining cyclic hot rolling with short‐time solution treatment was developed to improve the mechanical ...

Pore‐Defect Synergistic Decoupling of Electrical and Thermal Transport in Entropy‐Engineered Thermoelectric Ceramics

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Pore engineering reduces the thermal conductivity of thermoelectric materials, yet typically degrades electrical conductivity by enhancing carrier scattering—a long‐standing trade‐off. Here, we overcome this trade‐off in SrTiO3‐based entropy‐engineered ceramics via a one‐step synergistic strategy: using poly(methyl methacrylate) (PMMA) as a ...

Achieving Superior Strength–Ductility Synergy in an L12‐Type Ni3Al‐Based High‐Entropy Aluminide via Architecting Hierarchical Heterostructure

Rare Metals, Volume 45, Issue 11, November 2026.
ABSTRACT Achieving excellent strength–ductility synergy remains a critical scientific challenge for ordered Ni3Al‐based intermetallic alloys. In this work, a hierarchical heterostructure was deliberately architected in a novel L12‐type Ni3Al‐based high‐entropy aluminide, (Ni38.5Co38.5Al11.5Ti5Cr4.5Ta2)99.7B0.1C0.2 (at%), through a simple and cost ...

Eutectic Topology Regulates Deformation Pathways Enabling Synergistic Superelasticity and Strength in EBF3‐Fabricated NiTiNb Alloys

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The deformation behavior of NiTiNb shape memory alloys is governed by microstructural heterogeneity, specifically the interconnected topology of the β‐Nb phase. The regulatory role of the eutectic structure in load partitioning and the evolution of deformation mechanisms, particularly in high‐Nb systems, has not been clearly understood.
