Creep Investigation of SiCf-SiBC Composites

Scripta Materialia, 2005
The concept of ceramic matrix composites was proposed in the eighties to be used in the aeronautical and space domains. Classical SiCf-SiC have changed into complex materials, such as SiCf-SiBC investigated in this work: that composite is reinforced with SiC Hi-Nicalon fibers and has a multi-layer and self-sealing matrix.

Fabrication of Si3N4–SiBC composite ceramic and its excellent electromagnetic properties

Journal of the European Ceramic Society, 2012
Abstract To obtain better electromagnetic wave absorbing property, it is vitally necessary to develop novel ceramics with not only high dielectric loss but also low dielectric constant. Si3N4–SiBC, a composite ceramic with such dielectric properties, was fabricated by infiltrating SiBC into porous Si3N4 ceramic via low pressure chemical vapor ...

Anthropic soils in SiBCS and WRB: Review of criteria and conceptualization of the Anthropic horizon

Revista Brasileira de Ciência do Solo
The diagnostic anthropic A horizon in the Brazilian Soil Classification System (SiBCS) and the Pretic horizon in the World Reference Base for Soil Resources (WRB) comprise the surface mineral genetic horizons of soils formed under strong influence of

Damage Creep Mechanisms of SiCf-SiBC Composites

2008
In the 1373-1523K domain, the creep behavior of SiC f -SiBC batches tested under argon and 120 MPa has been investigated. The creep deformation of these composite is governed by a damage creep mechanism: first the creation of matrix microcracking until its saturation, then an opening of the microcracks in the transverse tows.

Soil Suborder Discrimination Using Machine Learning Is Improved by SWIR Imaging Compared with Full VIS–NIR–SWIR Spectra

Remote Sensing
Rapid, standardised discrimination of soil taxonomic units remains challenging when relying solely on conventional field descriptions and laboratory analyses, particularly at high sampling densities. This study evaluated whether proximal spectroscopy and

Relações edáficas e limitações dos solos do Parque Ecológico da Cascata, Sete Lagoas, MG

Scientia Plena
A área de proteção ambiental (APA) da Serra de Santa Helena, localizada na região central de Minas Gerais, é uma importante unidade de conservação que enfrenta ameaças devido ao pouco conhecimento sobre seus solos.
