AVALIAÇÃO DO COMPORTAMENTO EM FLUÊNCIA DA LIGA TI-6AL-4V COM ESTRUTURA MARTENSÍTICA E EQUIAXIAL A 600°C

Fatigue of Ti-6Al-4V

Metallic biomaterials have essentially three fields of use; these are the artificial hip joints, screw, plates and nails for internal fixation of fractures, and dental implants. Any of these devices must support high mechanical load and resistance of material against breakage is essential. High mechanical properties are needed for structural efficiency of surgical and dental implants. But their...

Avaliação da qualidade de agrupamentos em grafos

The process of discovering groups of similar, connected vertices in a graph, known as graph clustering, has interesting applications in several scenarios, such as biology, marketing and recommendation systems. A major challenge concerning this problem is the evaluation of cluster quality, which is used to measure the e ectiveness of clustering algorithms. Many quality metrics for graph cluster ...

Durability of Fe-Co Thin Films on Ti-6Al-4V

The durability of Fe-Co thin films bonded on Ti-6Al-4V was studied as a function of layer thickness at ambient temperature. Interface toughness of the thin films was characterized by indentation and analyzed using an interface fracture model. The critical stresses for interface debonding and the fatigue life response of Ti-6Al-4V with and without Fe-Co thin films were evaluated by three-point b...

Precision Grinding of Titanium (Ti-6Al-4V) Alloy Using Nanolubrication

In this current era of competitive machinery productions, the industries are designed to place more emphasis on the product quality and reduction of cost whilst abiding by the pollution-preventing policy. In attempting to delve into the concerns, the industries are aware that the effectiveness of existing lubrication systems must be improved to achieve power-efficient and pollutionpreventing ma...
