04.1 - Aerospace Grade Materials, Structural Analysis, Fatigue and Damage ToleranceFATIGUE PROPERTIES OF ADDITIVELY MANUFACTURED TOOL STEELC.M. Johnston¹, L.C. Tshabalala¹, M. Davids, University of the Witwatersrand, South Africa; ¹CSIR, South Africa Tool-steel is routinely used in South African wind tunnels for wind tunnel model parts and instruments. Additive Manufacturing is useful in this regard however knowledge of the fatigue characteristics of the material is required. Test specimens were manufactured from AM powder, using Selective Laser Melting, and tested. The results are presented. |
