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.

Micro-hardness method of studying intracrystalline liquation

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1952
1. Intra-crystalline liquation of alloys of aluminum and magnesium and of bismuth and antimony has been studied by the micro-hardness method. 2. The hardness of the alloys varies in accordance with the theoretical consideration previously advanced.

A nuclear tester for micro-hardness measurement

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2012
Abstract The dependence of alpha particle track diameter on the hardness of a diallyl maleate–allyl diglycol carbonate (DAM–ADC) nuclear track detector is investigated. When etched under optimum conditions, a relationship between track diameter and hardness is determined which is found to be linear.

Micro-Hardness Test of Cross-Linking LLDPE

Advanced Materials Research, 2017
The presented article deals with the research of micro-mechanical properties in the surface layer of modified linear polyethylene (LLDPE). These micro-mechanical properties were measured by the Depth Sensing Indentation - DSI method on samples which were non-irradiated and irradiated by different doses of the β - radiation (0, 66, 132 and 198 kGy ...
