Thermal Fatigue Behavior of AISI H13 Hot Work Tool Steel Produced by Direct Laser Metal Deposition
steel research international, Volume 94, Issue 4, April 2023., 2023 The thermal fatigue (TF) behavior of direct laser metal deposition‐H13 submitted to direct tempering (T‐H13) and quenching and tempering (QT‐H13) is investigated. T‐H13 shows slightly better TF resistance than QT‐H13, thanks to the higher tempering resistance, allowing the possible elimination of quenching, lower production costs as well as distortions‐

steel research international, Volume 94, Issue 4, April 2023., 2023 The focus of this investigation is to determine the effect of a wide variation of the CaF2 content in the slag on energy consumption, as well as on nonmetallic inclusion during electroslag remelting. The results indicate the potential to use slags with higher resistivity without significant losses in product quality.

steel research international, Volume 94, Issue 4, April 2023., 2023 Tool service life is limited by wear resistance and fatigue strength. Herein, a correlation of manufacturing‐related defect sizes and fatigue strength is presented. Powder metallurgy steels show significantly higher high‐cycle fatigue (HCF) strength than ingot cast steels.

Very high cycle fatigue under tension/torsion loading of mold low alloy steel
Fatigue &Fracture of Engineering Materials &Structures, Volume 46, Issue 2, Page 742-755, February 2023., 2023 Abstract Ultrasonic fatigue testing (UFT) is a recent fatigue methodology that applies resonance to achieve very high cyclic load frequencies. Its primary purpose is to study fatigue in the very high cycle fatigue regime. In this study, an UFT machine was used to conduct multiaxial tension/torsion fatigue tests at a 20‐kHz frequency.

Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 The effect of mold flux containing Ce2O3 on the contents of aluminum, silicon, and titanium in Incoloy825 super alloy was investigated based on the slag‐steel interfacial chemical reaction experiment between mold flux and alloy. Firstly, the activity model of the CaO‐SiO2‐Al2O3‐Na2O‐MgO‐CaF2‐Ce2O3 slag system was established according to the ion and ...
