Metal matrix composites are a type of material that has a lot of potential for components and structural applications that require a lot of unique modulus, strength, and durability as well as in the same time being light in weight... S Omran,MM Al-Masoudy,O Hassoon,... - 《Curved & ...
The absence of phase transformation and stability of the low elastic modulus values (e.g., ~60-70GPa) retained by the BSAS top layers after harsh environmental exposure provides a plausible explanation for the almost crack-free coatings observed. The relationships between the measured elastic ...
In the present work the elastic modulus of beta-Si6-xAlxOxN8-x ceramics with 5% of rare earth concentrate has been studied by a dynamic mechanical flexural method. The obtained results are discussed in terms of the coefficient x values, which in this case varied from 0.39 to 1.5, as well...
The pressure derivative of the elastic shear modulus of V3Si is calculated from 20 to 300 K in the linear chain model for the β-W compounds. The theory agrees with the experiment and predicts a different behavior for transforming and nontransforming single crystals. This is a preview of subs...
3.3. Elastic Anisotropy The anisotropy of mechanical properties is a key factor that affects the material’s properties. Microcracks usually appear, originating from the mechanical anisotropy of materials. In MoAlB crystal, the elastic modulus along different principal axes are expected to differ from ...
The physical properties, such as elastic modulus, locally change if the deviation occurs in some areas due to damage in the components. Those changes cause disturbances in the patterns of the vibration modes. If we recognize the irregular changes of the vibration pattern correctly, it is possible...

The elastic modulus E and resistivity ϱ of Fe Si B amorphous alloys are studied in this paper. The experimental results reveal the following: when metalloid content x < 25 at.%, E and ϱ increase with increasing x; when x = 25 at.%, E and ϱ reach maxima; when x > 25 at....
The excellent performance in the case of the Ni3P coating can be attributed to the smaller amount of coating, its high elastic modulus, and the moderate reactivity of Ni3P with Li. Zhang et al. reported the fabrication and characterization of a nanoscale Ni metal scaffold supported bicontinuous...
