A joint team from the University of Queensland, Australia (Jingqi Zhang et al.), Chongqing University (Ziyong Hou, Xiaoxu Huang), and the Technical University of Denmark has achieved in-situ alloying for the 3D printing process by adding Mo to Ti5553 metal powder.<\/p>\n\n\n\n<p>Specifically, by precisely delivering molybdenum into the molten pool, molybdenum can act as a seed nucleus for crystal formation and refinement during each layer scan, facilitating the transition from large columnar crystals to a fine equiaxed and narrow columnar crystal structure. Molybdenum also stabilizes the desired \u03b2-phase and inhibits the formation of phase heterogeneity during thermal cycling, by which not only the strength of the 3D printed titanium alloys is improved, but also a perfect balance of ductility and tensile properties is achieved.<\/p>\n\n\n<div   date-time="1730280545"   dir="fcvobg" class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"868\" src=\"https:\/\/test.srqwj.com\/wp-content\/uploads\/2024\/05\/image-13-1024x868.png\" alt=\"\" class=\"wp-image-1408\" srcset=\"https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-13-1024x868.png 1024w, https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-13-300x254.png 300w, https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-13-768x651.png 768w, https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-13.png 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n<div   date-time="1730280545"   dir="vrdhhm" class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"822\" src=\"https:\/\/test.srqwj.com\/wp-content\/uploads\/2024\/05\/image-14-1024x822.png\" alt=\"\" class=\"wp-image-1409\" srcset=\"https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-14-1024x822.png 1024w, https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-14-300x241.png 300w, https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-14-768x617.png 768w, https:\/\/srqwj.com\/wp-content\/uploads\/2024\/05\/image-14.png 1080w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<p>While TC4, the so-called workhorse of the titanium industry, has a recommended minimum elongation at break of 101 TP3T, the titanium 5553 prepared by this 3D printing has a great potential for application with a yield strength of 926 MPa and an elongation at break of 261 TP3T.
