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 ...

Tailoring Laser Powder Bed Fusion and Post‐Processing Parameters for JIS SKD61 Tool Steels: Surface Roughness, Microstructure, and Mechanical Properties

steel research international, EarlyView.
Laser powder bed fusion of JIS SKD61 tool steel is systematically optimized using a Taguchi design and ANOVA. Hatch spacing and layer thickness are identified as dominant parameters controlling surface roughness and tensile strength. Subsequent tempering at 600°C improves microstructural stability and mechanical performance, enabling high‐density SKD61

Toward the Application of Multiaxial Failure Criteria: Mean Stress Sensitivity of Carbide‐Rich, High‐Alloy PM‐HIP Tool Steels Under Axial and Torsional Cyclic Loading

steel research international, EarlyView.
This study quantifies axial and torsional long‐life fatigue (LLF) behavior of three carbide‐rich PM‐HIP tool steels, correlating LLF strength with intrinsic defect size and cleanliness, thereby extracting material‐specific mean stress sensitivities and Haigh diagrams.

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.

Architecting and Industrializing Advanced Production and Manufacturing Systems for Critical Industries

Systems Engineering, EarlyView.
ABSTRACT Advanced production systems play a vital role in modern society. Such systems are developed and industrialized over multiple years and at great expense. The complexities of these systems are exacerbated in the case of metal additive manufacturing, which involves numerous process variables and relies on various auxiliary systems.
