Micro-hardness of surface layer of irradiated polypropylene [PDF]
Using high doses of beta radiation for polypropylene (PP) and its influence on the changes of micromechanical properties of surface layer has not been studied in detail so far. The specimens of PP were made by injection moulding technology and irradiated by high doses of beta radiation (0, 33, and 66 kGy).

Micro-hardness measurement of photopolymer in stereolithography.
The curing of liquid photopolymer is determined by the exposure (optical energy) deposited. In laser stereolithography, laser exposure is considered as non-homogenous within the radiation area. In order to investigate the difference of the cure degree within the cross section of a single cured strand, a micro-structure was evaluated by hardness ...
