Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

Advanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

INVESTIGATION OF THE EFFECT OF DEPTH OF CUT AND CUTTING SPEED ON CUTTING FORCES DURING FACE MILLING OF STEEL WITH A RECTANGULAR CUTTING INSERT

Cutting & Tools in Technological System, 2019
У процесах механічної обробки металу бажано досягнення досить високої швидкості видалення матеріалу. Швидкість видалення матеріалу може бути збільшена до бажаного значення шляхом збільшення значення швидкості подачі, а також шляхом збільшення швидкості різання або глибини різання.

DigiChrom: A Domain Ontology for Semantic Representation of Trivalent Chromium Platings and Its Large Language Model‐Based Alignment With Multiple Mid‐Level Ontologies

Advanced Engineering Materials, EarlyView.
Digitalizing electroplating requires both domain knowledge and interoperability. This work introduces PlatOn, a domain ontology for trivalent chromium plating and coating characterization, and a hybrid pipeline that aligns it to a mid‐level reference ontology by combining eight similarity metrics with language model reasoning. Expert‐validated mappings

Study on Rubbing-Cutting Transition Phenomena at the Depth of Cut Increase Gradually

Journal of the Japan Society of Precision Engineering, 1968
Rubbing-cutting transition phenomena are studied on the orthogonal cutting in which depth of cut increases gradually.Specimens of steels with various hardness are cut by two dimentional tools of SKH4 that have various roundness of cutting edge. On that occasion the thrust component of cutting force falls down suddenly when a pilled-up material on the ...

Investigating the Effect of Inclination Angle and the Influence of Scan Parameters on the Appearance and Thermal and Mechanical Properties of Filigree Tension Rods of LPBF‐Manufactured NiTi Shape‐Memory Alloys

Advanced Engineering Materials, EarlyView.
This article investigates the dependence of the properties on the manufacturing orientation in the form of the inclination angle to the build plate of LPBF‐fabricated NiTi rods with a diameter of 150–220 µm. Metallographic, chemical, thermal, and mechanical characterization show behavior under identical manufacturing conditions that ranges from ...
