Effects of Microstructure and Relative Density on the ...

This work studies the effects of microstructure and relative density on the dielectric constant of porous silica prepared by two different techniques: gelcasting of suspension (GCS) and gelcasting of …

Effects of processing parameters on relative density ...

In particular, the influences of operating temperatures, imposed back-pressures and the number of passes on the relative density, hardness, homogeneity and microstructure evolution were discussed. (1) The relative density of the as-recycled products increased with the applied back-pressure and number of passes.

Effect of relative density on microstructure and ...

The microstructure features and compressive strength of sintered Fe-12 wt.% Mn-0.2 wt.% C alloy steel have been investigated by considering the effect of relative density. Both the relative density and the strength increased linearly irrespective of the initial relative density during the room-temperature compressive test.

Effect of Hot Pressing Variables on the Microstructure ...

Effect of Hot Pressing Variables on the Microstructure, Relative Density and Hardness of Sterling Silver (Ag-Cu alloy) Powder Compacts The Vickers hardness evaluation (Microhardness tester,

Effects of sintering temperature on the microstructure …

Effects of sintering temperature on the microstructure and dielectric properties of titanium dioxide ceramics ... (relative density with respect to the theoretical density) of

Study of NiZn Ferrite Complex Permeability - Effect of ...

An equation is proposed that enables relating the magnetic loss factor to fired relative density, average grain size, and grain size distribution width. This equation is valid for the ferrites studied, which had an average grain size below 10 μm and a grain size distribution width below 30 μm.

Effect of BaO addition on relative density and electric ...

The effects of BaO addition on relative density, microstructure and electric conductivity of cermets were investigated. The results show that relative densities of x Ni/10NiO-NiFe 2 O 4 cermets ( x =5,

Effect of Powder Size on Microstructure and Mechanical ...

This paper studied the effects of powder size on densification, microstructure, and mechanical properties of the hot isostatic-pressed 2A12 aluminum alloy powder compact. The results show that the near-fully dense powder compact can be successfully achieved and the smaller the powder is, the higher the relative density is.

Study of NiZn Ferrite Complex Permeability - Effect of ...

Equation (5), which relates the magnetic loss factor to sintered relative density and the principal microstructural char- acteristics, enables determining the values of sintered relative density, average grain size, and grain size distribution width required to achieve a given complex relative permeability.

The effect of laser energy input on the microstructure ...

Despite the advantages of high energy input (2E 0) on the relative density, microstructure and mechanical properties, it reduces the surface quality compared to the baseline energy condition (E 0).
