Micro-Hardness of PBT Influenced by Beta Radiation [PDF]
MATEC Web of Conferences, 2016 Cross-linking is a process in which polymer chains are associated through chemical bonds. Radiation, which penetrated through specimens and reacted with the cross-linking agent, gradually formed cross-linking (3D net), first in the surface layer and then in the total volume, which resulted in considerable changes in specimen behaviour.

A new method for hardness determination from depth sensing indentation tests [PDF]
, 1996 A new semiempirical formula is developed for the hardness determination of the materials from depth sensing indentation tests. The indentation works measured both during loading and unloading periods are used in the evaluation.
