Micro-Hardness of Irradiated Polyamide

Defect and Diffusion Forum, 2016
The influence of beta radiation on the changes in the structure and selected properties (mechanical and thermal) was proved. Using high doses of beta radiation for glass fiber filled polyamide (PA) and its influence on the changes of micromechanical properties of surface layer has not been studied in detail so far.

A Micro-Hardness Tester

Journal of Scientific Instruments, 1947
An instrument of simple design is described by means of which the hardness of a material at microscopically determined points on its surface can be measured. Details are given of its construction, calibration and use, together with results of some typical tests carried out with it.

Comparison of Ultrasonic-Hardness-Tester Hardness and Micro-Vickers Hardness

Japanese Journal of Applied Physics, 2007
Examination methods of industrial hardnesses such as Vickers hardness and Rockwell hardness are used for the characteristic measurement of materials. These methods assume that the length of the plastic deformation is a reliable index of hardness. Since the indenters used in these methods produce deformation imprints and the methods themselves are ...

Hardness and Micro-Indentation Hardness Comparison of Recycled Modified HDPE

Key Engineering Materials, 2014
This research paper deals with the possible utilization of irradiated high-density polyethylene (HDPE) after its service life. Powder of recycled irradiated HDPE is used as filler into virgin low-density polyethylene (LDPE) in concentrations from 10 to 60 %. Two combinations of materials were tested granules LDPE/powder HDPE and powder LDPE/powder HDPE.

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 ...
