Abstract
The invention discloses a kind of seamed pipe manufacturing methods of titanium alloy, the ingredient for the titanium alloy round billet that this method uses is aluminium 7.3 7.9%, molybdenum 0.3 0.8%, tin 2.5 3.1%, carbon 0.03 0.08%, surplus are titanium, then carries out extrusion forming as raw material using the round billet and carries out heat treatment and quenching treatment.The seamed pipe manufacturing method of titanium alloy of the present invention is using the round billet containing less alloying element as raw material, titanium alloy round billet and shaping pipe are all heat-treated in entire manufacturing process, also quenched with cold water, be conducive to titanium alloy seamed pipe after molding in this way and absorb more welding stresses in welding, the generation for reducing cold crack, to effectively improve the solderability of titanium alloy seamed pipe.
Description
Technical field
The present invention relates to titanium tube manufacturing fields, more precisely, being a kind of seamed pipe manufacturing method of titanium alloy.
Background technology
Titanium is a kind of important structural metal to grow up the 1950s, and titanium alloy is because high, anti-corrosion with intensity
The features such as property is good, heat resistance is high and be widely used in every field.Many countries all recognize the weight of titanium alloy material in the world
The property wanted in succession researchs and develops it, and is applied.Mainly develop aviation hair 50~sixties of 20th century
The high-temperature titanium alloy of motivation and the structural titanium alloy of body, develop a collection of corrosion resistant Ti alloy the seventies, since the eighties,
Corrosion resistant Ti alloy and high-strength titanium alloy are further developed.Titanium alloy is mainly used for making aircraft engine compressor part,
Secondly it is rocket, the structural member of guided missile and high-speed aircraft.Titanium alloy seamed pipe is a kind of using relatively broad tubing, current system
The method for making titanium alloy seamed pipe is varied, but when titanium alloy seamed pipe is welded after shaping, it can be larger
Occur cold crack under the action of welding stress, directly affect the normal use of titanium alloy seamed pipe, shows to subtract by analysis
The probability of happening of few cold crack must reduce the alloying element of titanium alloy, expand the quenching range of titanium alloy, be closed to improve titanium
The solderability of golden seamed pipe.
