Microstructural, mechanical and electrochemical characterisation of biomaterial ASTM F745 cast by vacuum
(Maney Publishing, 2012-06)
Countergravity low pressure casting (CLA) was performed to enhance the properties of ASTMF745 stainless steel (SS), which is usually used as biomaterial. The macro- and microstructureswere compared with those obtained by ...
Comparative study of two commercially pure titanium casting methods
(Faculdade De Odontologia De Bauru - USP, 2010)
The interest in using titanium to fabricate removable partial denture (RPD) frameworks has increased, but there are few studies evaluating the effects of casting methods on clasp behavior. OBJECTIVE: This study compared ...
Does the casting mode influence microstructure, fracture and properties of different metal ceramic alloys?
(SOCIEDADE BRASILEIRA DE PESQUISA ODONTOLOGICASAO PAULO, 2012)
The aim of the present study was to evaluate the tensile strength, elongation, microhardness, microstructure and fracture pattern of various metal ceramic alloys cast under different casting conditions. Two Ni-Cr alloys, ...
On vacuum density, the initial singularity and dark energy
(Springer Verlag, 2009)
Standard cosmology poses a number of important questions. Apart from
its singular origin, it possesses early and late accelerating phases required to account
for observations. The vacuum energy has been considered as a ...
Indications Of A Nontrivial Vacuum In The Effective Theory Of Perfect Fluids
(AMER PHYSICAL SOCCOLLEGE PK, 2015)
The Effect of Coating Patterns with Spinel-Based Investment on the Castability and Porosity of Titanium Cast into Three Phosphate-Bonded Investments
(WILEY-BLACKWELL, 2010)
Purpose: This study evaluated the effect of pattern coating with spinel-based investment Rematitan Ultra (RU) on the castability and internal porosity of commercially pure (CP) titanium invested into phosphate-bonded ...
