Applicability of the Ti6Al4V Alloy to the Roller Arm for Aircraft Parts Made Using the DMLS Method

Applicability of the Ti6Al4V Alloy to the Roller Arm for Aircraft Parts Made Using the DMLS Method Additive manufacturing (also called 3D printing) technology is so well known that it is inaccurate to call it a new technology anymore, and it is being applied in many industrial fields. In the aviation industry, the influence of process variables and post-treatment processes on additive manufacturing technology has been studied extensively. In this study, the mechanical properties of aircraft parts made of Ti6Al4V powder and their suitability for applications involving aircraft were reviewed. A specimen was prepared and tested; then its microstructure was analyzed and compared with Ti6Al4V plate material. Selected mechanical properties were reviewed. The target product was fabricated using the same process parameters under the same conditions as used for the specimen. The influence analyses of the build orientation and post-processing were performed by dividing the build orientation of the target product into three parts. The shape deformation that occurred after post-processing was reviewed. In addition, the adequacy of the target product to resist the required loads was determined through a functional test of the product. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png International Journal of Aeronautical and Space Sciences Springer Journals

Abstract

Additive manufacturing (also called 3D printing) technology is so well known that it is inaccurate to call it a new technology anymore, and it is being applied in many industrial fields. In the aviation industry, the influence of process variables and post-treatment processes on additive manufacturing technology has been studied extensively. In this study, the mechanical properties of aircraft parts made of Ti6Al4V powder and their suitability for applications involving aircraft were reviewed. A specimen was prepared and tested; then its microstructure was analyzed and compared with Ti6Al4V plate material. Selected mechanical properties were reviewed. The target product was fabricated using the same process parameters under the same conditions as used for the specimen. The influence analyses of the build orientation and post-processing were performed by dividing the build orientation of the target product into three parts. The shape deformation that occurred after post-processing was reviewed. In addition, the adequacy of the target product to resist the required loads was determined through a functional test of the product.
