The mechanical strength of sintered porous titanium plates is influenced by their porosity. Generally, an increase in porosity leads to a decrease in mechanical strength.
Porosity creates stress concentration points within the material, which can weaken it and make it more prone to fracture under load. Higher porosity means a less dense and more porous structure, resulting in reduced overall strength.

However, the relationship between porosity and mechanical strength is not always straightforward. In certain cases, porosity can actually enhance the mechanical properties. A small amount of porosity, for instance, can improve toughness and ductility, making the material more resistant to deformation and better at absorbing energy before fracturing.
The impact of porosity on mechanical strength depends on various factors, including pore size, distribution, manufacturing process, and intended application. Therefore, it is crucial to consider the porosity of sintered porous titanium plates carefully when designing components that require specific mechanical properties.
