Micro-Hardness of Irradiated Polyamide
Defect and Diffusion Forum, 2016The 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.

Comparison of Ultrasonic-Hardness-Tester Hardness and Micro-Vickers Hardness
Japanese Journal of Applied Physics, 2007Examination 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, 2014This 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.
