Tungsten Copper FGM Flexural Strength
Tungsten copper FGM flexural strength refers to the capability of resistance to external force. Generally, it uses three-point bending test or four-point test method for evaluation.
1. Mechanical properties: The performance of the material by external force; 2. Stress: The reaction material inside to external force. The magnitude of the stress by the following equation: stress (δ) = Effect (F) / unit area of material (A), in units of Pa; 3. Strain: The deformation of material caused by external force. Strain magnitude represented by the following equation: strain (ε) = length change (△L) / initial length (L); 4. Tensile stress, compressive stress, shearing stress.
The flexural strength of W-Cu gradient composites with different layers as the pressure-receiving surface on different surfaces is the flexural strength of different surface. Three-layer and four-layer structure of the gradient composite material to use W-50Cu for the bearing surface, the flexural strength obtained higher than that with W-20Cu as the pressure bearing surface, which shows that the mechanical properties of FGM show a gradient change along the direction of Cu content increasing. In addition, four-layer structure of the gradient material has higher interface bonding strength and smaller residual stress so the resistance to destruction is much better.
