Under controlled conditions, solidification from the melt leads to materials without porosity and with a very low amount of grain boundaries.
Because the outstanding stability of their microstructures up to temperatures close to the melting point as well as their corrosion resistance, "in situ" composites could be promising materials for high-temperature structural applications.
However, fracture toughness of materials as Al2O3-YAG eutectic is low.

Materials and methods Experimental materials.
The higher the temperature, the more the new pigment materials.
All of above not only effectively inhibited the new generation of pigment materials but also produced the fine particles of calcium sulfite removing more pigment materials effectively through entrapping, bridging and adsorption of the flocculation; With the improving of the sulfitating strength, more and more calcium sulfite formed.

The conversions of the thermal conductivity to design values can be done using the following formulas: FT=efTT2-T1 (1) Fm=efψψ2-ψ1 (2) λ2=λ1∙FT∙Fm∙Fa [W·m-1·K-1] (3) where FT, Fm are the conversion factors of temperature, moisture and ageing. fT is the temperature conversion coefficient, fψ is the moisture conversion coefficient volume by volume which values are specific to the materials.

When it comes to detecting physical signals, as body pressure, carbon-based materials are an adequate resource, mainly due to their thermal and mechanical properties, along with their piezoresistive behavior, that is, the ability to change its electrical resistance from a mechanical deformation.
Among these, graphene nanoplatelets (GNPs) have a more affordable price when compared to other carbon-based materials, making it more applicable on an industrial scale [6, 7].
Plasma treatment is a surface treatment of different materials that takes place from the equal discharge of positively and negatively charged particles [11].
Experimental Materials and methods Materials.
It is also possible to observe an increase in roughness in the samples that received the corrosion treatment with NaOH, due to the extraction of low molecular weight materials and the presence of lignin in them [15].

Additive manufacturing technology is a manufacturing method by accumulating materials layer by layer.
However, in the process of additive manufacturing, the materials are often accompanied by segregation phenomena and non-equilibrium structure and tends to generate residual stress, which seriously affects the mechanical properties of the as-fabricated materials.
