چکیده
In this paper, the influence of a blunt notch on VHCF response SLM Ti6Al4V specimens is investigated. Ultrasonic fully reversed tension–compression tests up to 109 cycles were carried out unnotched and with notch. Unnotched show slightly larger fatigue response, limited differences. All failures originated from defects, which are bigger in specimens, mainly due different risk volume tested related size effect. Interactions between notch, stress gradient, defect distribution must be considered properly assess response.

Fatigue of Ti6Al4V Structural Health Monitoring Systems Produced by Selective Laser Melting
Selective laser melting (SLM) is an additive manufacturing (AM) process which is used for producing metallic components. Currently, the integrity of components produced by SLM is in need of improvement due to residual stresses and unknown fracture behavior. Titanium alloys produced by AM are capable candidates for applications in aerospace and industrial fields due to their fracture resistance,...

Selective laser melting (SLM) is a novel technique being increasingly used for the production of porous structures with a high degree of precision and near net shape. These porous materials are finding their use in the biomedical industry for implants. In this thesis, the effect of post-processing using hot isostatic pressing (HIP) and surface modification techniques, such as chemical etching a...
متن کاملInfluence of heat-treatment on Selective Laser Melting products – e.g. Ti6Al4V
Usually additive manufactured metal parts are showing a different mechanical behavior compared to conventionally produced parts used the same material. Apart from process-related macroscopic part imperfections (pores, surface roughness, etc.) the microstructure has a decisive influence on the mechanical properties of the materials. Thus, in order to optimize mechanical properties of metal parts...
متن کاملPerformance of High Layer Thickness in Selective Laser Melting of Ti6Al4V
To increase building rate and save cost, the selective laser melting (SLM) of Ti6Al4V with a high layer thickness (200 μm) and low cost coarse powders (53 μm-106 μm) at a laser power of 400 W is investigated in this preliminary study. A relatively large laser beam with a diameter of 200 μm is utilized to produce a stable melt pool at high layer thickness, and the appropriate scanning track, whi...
