Project description:

The main objective of the 3TANIUM is the establishment of NDT methods that are capable to provide the secure detection of process related critical flaws and defects and to understand their effects on material and mechanical properties in Ti6A l4V AM parts. The overall aim of the proposed 3TANIUM project is the quantitative assessment of the applicability of NDT methods applied on appropriately and innovatively post-treated (heat- and surface-treated) AM parts to realize benefits offered by AM in the aeronautical industry. Therefore, evaluation of reliable Non-Destructive Testing and Analysis (NDT/NDA) techniques for precisely and securely assessing eventual defects and their criticality in AM parts will be performed.

The work plan of the proposed research has been established according to the topic description instructions. The 3TANIUM project is structured into four technical work packages (WP1 to WP4), covering all technical work starting from planning the specimen and characterization matrix, fabrication of specimens and their characterization and performing mechanical, NDT and material testing. WP1 provides a completed specimen and testing matrix to be able to investigate the effects of different manufacturing parameters on mechanical and fracture properties of titanium AM specimens. Also in this work package the required specimens will be fabricated. The testing will be realized in WP2 (NDT) and WP3 (mechanical, fatigue, materials testing). In WP4, with respect to the quantified defects in WP2 and WP3, industrial relevant fatigue life prediction methods by modelling and simulation approaches will be carried out. In WP5 assessment and reporting will be performed by linking processing parameters with NDT results, mechanical properties and results of modelling to draw the final conclusions and lessons learnt in order to be able to define recommendations. A work package is devoted to exploitation, dissemination, and communication activities and to management activities (WP6).

VZLU is responsible for material characterization and testing, test matrix developing, methodology for interrupted experiments, data analysis, non-destructive testing using ultrasonic and eddy current method,  FE modelling of tested specimens assembly, typical AM defect simulation, input material characteristics evaluation, fatigue life and crack growth computing (using ABAQUS and FE-SAFE SW).
