Welding of titanium alloys with steels presents a high risk of cold cracking because of the formation of extremely brittle intermetallic phases associated with residual stress. The use of solid state and diffusion-based methods as well as a high power beam welding allow so far to achieve good tensile properties through the control of a local phase content. This review summarizes existing approaches for the creation of defect-free joints between titanium alloys and steels: direct joining without a filler material, the use of insert having full metallurgical compatibility with titanium, the use of insert compatible with stainless steel, and multilayer engineering.

“…On the contrary, Nb weakened the alloy and the Vickers hardness number of Sample 11 decreased to 381. Nb has not only a large solubility in Ti, but can also help to dissolve Fe in Ti [32,33]. Therefore, the added 5 wt.% of Nb effectively kept Fe in ␤-Ti and prevented the formation of Fe-Ti intermetallics.…”

“…Необходимо было создать сплав, не содержащий титан, но обладающий требуемыми свойствами. Исследования фазовых равновесий в сплавах кобальта с карбидами тугоплавких металлов [4,5] и представление о возможности получения естественного композита в условиях равновесной эвтектической кристаллизации из расплава [6], позволило разработать литейный износостойкий сплав на основе кобальта с карбидом ниобия не содержащий титан [7]. Сплав внедрён под маркой ХТН-61 и внесён в чертежи производства двигателей на предприятиях ОАО «Мотор-Сич» и ГП ЗМКБ «Прогресс» согласно «Техническим условиям» (ТУ) [8] и используется в турбинах крупногабаритных двигателей Д18Т, устанавливаемых в самолётах АН-225 «Мрія» и АН-124 «Руслан».…”
