(2024). Microstructure and fracture toughness of laser wire deposited Ti-6Al-4V. Journal of Alloys and Metallurgical Systems, vol. 7, September 2024, 100090.<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>In this paper, the microstructure, and mechanical properties of Ti-6Al-4V fabricated through\u00a0Laser Directed Energy Deposition\u00a0(L-DED) process are investigated and discussed. Deposited coupons were produced on Ti-6Al-4V wrought substrate using Ti-6Al-4V ELI grade wire with the laser wire deposition (LWD) process. Characterization efforts led to the evaluation of the microstructure, hardness,\u00a0tensile behavior, and\u00a0fatigue crack growth\u00a0resistance of the build-up alloy. Microstructure of the deposit consists of columnar prior \u03b2 grains and basket-weave \u03b1\/\u03b2 phase mixture. The size of the alpha laths is measured as 1.2 \u00b1 0.3\u202f\u00b5m and 0.8 \u00b1 0.2\u202f\u00b5m in the banded zone and band-free zone, respectively. Hardness of the deposited block is found to be uniform and ranging between 321 and 323\u202fH<sub>v<\/sub>. Tensile and\u00a0fatigue crack growth\u00a0properties of the deposited block were evaluated in various orientations.\u00a0Tensile specimens\u00a0loaded in the deposition direction exhibited 824\u202fMPa and 930\u202fMPa for yield and\u00a0ultimate tensile strength, respectively. Tensile specimens loaded in the build direction exhibited 782\u202fMPa and 907\u202fMPa for yield and\u00a0ultimate tensile strength, respectively. The analysis reveal that the\u00a0tensile properties\u00a0of the deposited material match the\u00a0strength\u00a0requirements for ASTM F1108 Cast Ti-6Al-4V. However, they fell just below the AMS 4911P Wrought Ti-6Al-4V standard. Fatigue\u00a0Crack Growth Rate\u00a0tests were conducted for three directions: parallel to the deposition direction, parallel to the build direction and at 45\u00b0 of the deposition direction. No significant differences in crack growth properties were observed between the different orientations with average crack initiation near threshold (\u0394K<sub>th<\/sub>) and the\u00a0fracture toughness\u00a0(K<sub>c<\/sub>) value of 3.6\u202fMPa\u221am and 69\u202fMPa\u221am, respectively. The\u00a0crack propagation\u00a0properties are similar to cast &amp; wrought materials.<\/p>\n<p>&nbsp;<\/p>\n<p class=\"link-btn-style btn-yellow\"><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2949917824000373\" target=\"_blank\" rel=\"noopener\">Read the publication<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Chainiau, F.; Sikan, F.; Ding, Y.; Brochu, M.
