Abstract

FIELD: metallurgy, alloys. SUBSTANCE: alloy has components at the following ratio, wt. -% : aluminium 1-6.8; vanadium 2-9; molybdenum 1-3.8; zirconium 1-4; chrome 0.4-1.8; iron 0.4-1.8; silicon 0.04-0.14; nitrogen 0.006-0.05; hydrogen 0.002-0.014; tin 1-4, and titanium - the rest. Tin addition to the proposed alloy enhances its structural strength up to 125 - 130 kgf/mm2 (after annealing) and 145 - 150 kgf·mm2 after hardening in water, uniform plasticity up to 8-9 and 5-6%, respectively, after annealing and hardening and ageing and concentrated plasticity up to 35-40 and 20-25% , respectively, after annealing and hardening and ageing. Alloy is used for making of articles used in aerospace equipment. EFFECT: enhanced mechanical properties of alloy. 2 tbl

Description

Изобретение относится к цветной металлургии, в частности к сплавам на основе титана, предназначенным для изготовления изделий авиакосмической техники. The invention relates to non-ferrous metallurgy, in particular to titanium-based alloys intended for the manufacture of aerospace engineering products.

Целью изобретения является повышение механических свойств сплава. The aim of the invention is to increase the mechanical properties of the alloy.

Введение в предложенный сплав олова обеспечивает эффективное упрочнение альфа- и бета-твердых растворов и повышение механических свойств сплава в отожженном и термически упрочненном состояниях. Introduction to the proposed alloy of tin provides effective hardening of alpha and beta solid solutions and increase the mechanical properties of the alloy in annealed and thermally hardened states.

Составы предложенного и известного сплавов, приведенные в табл.1, выплавляли в вакуумных дуговых печах. Слитки ковали на прутки и прокатывали в листы. Механические свойства образцов, приведенные в табл.2, определяли как после отжига, так и после закалки в воде и старения. The compositions of the proposed and known alloys shown in table 1, were smelted in vacuum arc furnaces. The ingots were forged and rolled into sheets. The mechanical properties of the samples shown in Table 2 were determined both after annealing, and after quenching in water and aging.

Как следует из приведенных в таблицах данных, предложенный сплав на основе титана обеспечивает по сравнению с известным сплавом повышение конструкционной прочности и пластичности на 19-25 и 35-100% соответственно. As follows from the data in the tables, the proposed alloy based on titanium provides, compared with the known alloy, an increase in structural strength and ductility by 19-25 and 35-100%, respectively.
