PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

Small, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels

steel research international, EarlyView.
The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Influences of Cleanliness, Carbide Size, Hardness, and Residual Stresses on Long‐Life Fatigue Strength and Crack‐Initiation Mechanisms in Carbide‐Rich Cold‐Work Tool Steels Using Normalized S–N Curves and Database‐Driven Validation of Murakami's √Area Model

steel research international, EarlyView.
Rotating‐bending fatigue tests on AISI D2 and AISI A11 quantify how cleanliness, carbide structure, hardness, and fabrication‐induced compressive residual stresses govern long‐life fatigue at NG = 107 cycles. Statistical fracture‐surface analysis and extreme‐value √area statistics link crack‐initiators to LLF strength.

Multi‐Scale Mechanical Behavior of Additive‐Manufactured 316L Stainless Steel Processed by Severe Plastic Deformation

steel research international, EarlyView.
The multi‐scale mechanical behavior of additive‐manufactured 316L stainless steel processed by directed energy deposition and high‐pressure torsion is explored. The influence of torsional strain on strength and microstructural evolution is revealed, indicating progressive grain refinement in the ultrafine regime, reaching strength levels nearing 1800 ...

Atomic‐Scale Insights Into Tramp Element Segregation and Mechanical Performance of a Low‐Carbon Steel

steel research international, EarlyView.
Despite increased hardness, elevated tramp element concentrations in a ferritic‐pearlitic low‐carbon steel lead to enhanced toughness accompanied by a more homogeneous and finer ferritic microstructure. Atom probe tomography reveals pronounced segregation of some tramp elements at grain boundaries and ferrite–cementite interfaces, together with ...
