Tropical woods: influence of density in hardness parallel and normal to the grain for some Brazilian tropical tree species
(IPEF-INST PESQUISAS ESTUDOS FLORESTAIS, 2010)
The aim of this work is to verify the possibility to correlating specific gravity and wood hardness parallel and perpendicular to the grain. The purpose is to offer one more tool to help in the decision about wood species ...
Study of the Orbital Hardness and the Kohn-Sham Radius on Single Monoatomic Anions
(WILEY, 2011)
Within the Kohn-Sham framework and for a series of single charged monatomic anions, the orbital hardness is calculated as a change in the frontier eigenvalue, which is equivalent to integrate the local hardness function ...
Influência do escoamento estático (CREEP) na dureza do amálgama. Efeito de ligas e regióes de medida.
(1990-05-01)
The authors studied the CREEP of 5 amalgam alloys (1 conventional and 4 with high cooper) by the application os static load of 36 MPa in 478 mm specimens, 7 days old. After CREEP test, the samples were included in acrylic ...

High-velocity oxyfuel Cr3C2-NiCr replacing hard chromium coatings
(Asm International, 2005-09-01)
Comparative wear and corrosion properties of Cr3C2-NiCr (CC-TS) (a high-velocity oxyfuel [HVOF]) and hard chromium (HC) coating's obtained on a steel substrate have been studied. The structural characterization was done ...
