The Investigations of Surface Micro-Hardness of Experimental Hard Alloy Grades

2021
The article is dedicated to evaluation of surface dynamic micro-hardness of experimental hard alloy grades with modified binder constructed on the base of standard single-carbide grade VK8. Connections between micro-hardness and absolute thermo-EMF together with thermal entropy of an alloy as integrated characteristics of its chemical composition and ...

Micro-Hardness and Micro-Wear Measurements on Magnetic Heads

2003
Wear of carbon coated sliders during contact start stop testing was measured by monitoring changes in the depths of ion milled “trenches” in the airbearing surface. Wear was determined as a function of sliding distance and glide height of the media. In addition, nano-hardness measurements were used to characterize the carbon overcoats.

Effect of annealing on microstructure, texture and hardness of ITER-specification tungsten analyzed by EBSD, vickers micro-hardness and nano-indentation techniques

Journal of Nuclear Materials, 2019
Tungsten and its alloys have been extensively studied to be used as materials for plasma facing components (PFCs) in future nuclear fusion reactors. Under fusion operating conditions, the surface of PFCs will experience high heat flux exposure which will

The effect of cutting parameters on micro-hardness and the prediction of Vickers hardness based on a response surface methodology for micro-milling Inconel 718

Measurement, 2019
The poor characteristics of Inconel 718, such as large plasticity, low thermal conductivity, and sensitivity to the strain rate, lead to serious problems in its micro-milling, particularly its work hardening, which lowers the fatigue and the corrosion ...

Micro-structure and micro-hardness of ODS steels after ion irradiation

Journal of Nuclear Materials, 2011
Abstract The radiation-hardening of oxide dispersion strengthened (ODS) alloys was examined using ion irradiation and nano-indentation. In this work, three ODS steels were irradiated in the TIARA facility at JAEA with 10.5 MeV Fe 3+ ions up to a dose of 20 dpa at 250 and 380 °C.
