Utilizing TiC Cermet in Face-Milling

Bulletin of JSME, 1963
A higher production rate of face-milling will be realized if a more abrasion resistant but less tough tool material can be used without breakage. For this purpose, titanium carbide cermet tool material is studied for utilization in steel face-milling. The main problem is to provide the effective land and the proper rake angle to the cutting edge.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

INVESTIGATION OF SURFACE ROUGHNESS CHARACTERISTICS OF FACE MILLING

Cutting & Tools in Technological System, 2019
Surface quality and accuracy affect the integrity and lifetime of machine parts and the operational requirements of the structural (or assembly) units. These are the reasons that the expected surface roughness must be planned based on the operational requirements of the parts.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.
