Analysis of the Indentation Size Effect in the Microhardness Measurements in B6O

open access: yesAdvances in Materials Science and Engineering, 2011
The Vickers microhardness measurements of boron suboxide (B6O) ceramics prepared by uniaxial hot-pressing was investigated at indentation test loads in the range from 0.10 to 2.0 kgf.

Effect of CPP-ACPF, resin infiltration, and colloidal silica infiltration on surface microhardness of artificial white spot lesions in primary teeth: An in vitro study

open access: yesDental Research Journal, 2022
Background: Remineralizing agents such as fluoride and casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) are popular treatment choices for incipient enamel lesions. Recently introduced resin infiltration enhances the esthetics of teeth affected

Some methodological contributions to the Vickers microhardness technique

open access: yesPolymer Testing, 2000
Some additional possibilities for microhardness investigations of polymer materials using a standard Vickers microhardness device are discussed. Two new investigation methods have been suggested: determining the impression size under a load; obtaining penetration curves.

Elastic recovery effect on vickers microhardness of hard coatings [PDF]

open access: yes, 1997
It has been commonly assumed that there is no elastic recovery in the Vickers indent diagonal on unloading and Vickers microhardness is load independent.

Surface layer microhardness and roughness after applying a vibroburnishing process

open access: yesJournal of Materials Research and Technology, 2019
The ball vibroburnishing process of external cylindrical surfaces involves workpiece rotation, while a ball is being pressed and forced to roll on the cylindrical surface, simultaneously, achieving an axial vibration.

PROPERTIES OF COMPOSITE RESIN ALKASIT AND ZIRCONIA-REINFORCED GLASS-IONOMER CEMENT IN DIFFERENT STORAGE

open access: yesODONTO: Dental Journal, 2020
Background: The temperature and salivary pH in a person's mouth are highly dynamic (e.g., before, during, and after eating) and so restorations in a cavity must be resilient to these variable conditions.

Correlation between microhardness and microstructure of low-temperature Sn-xBi-M(Ag, Sb) solders

open access: yesJournal of Materials Research and Technology
The correlation between Vickers microhardness and microstructure of low-temperature Sn-xBi-M(Ag, Sb) solders was investigated. The β-Sn grains were refined with increasing Bi content, as well as the additions of Ag and Sb.
