Original Title: Introduction to Common Technologies for Hot Extrusion of Titanium Alloy Bars Introduction of Hot Extrusion Technology for Titanium Alloy Bar The hot extrusion of titanium alloy rod is to extrude the powder under the condition of increasing the temperature, so that the product can achieve full densification. Hot extrusion can accurately control the composition of the material and the internal structure of the alloy. Hot extrusion method can be divided into two forms: jacketed hot extrusion method and non-jacketed hot extrusion method. For the active metal titanium and titanium alloy powder,3d titanium wire, in order to prevent the product from oxidation, the hot extrusion method is often used. At this time,Titanium welding pipe, first make the sheath, put the powder or compact in the sheath, titanium filler rod ,nickel titanium wire, after pre-pumping and sealing, put it in the extruder for hot extrusion. At this time, the sheath material used should have good thermoplasticity, not form full gold with the release material, easy to peel off after hot extrusion, convenient source and low cost. Low carbon steel or stainless steel sheet is mostly used. The first process of hot extrusion of titanium alloy bar is to combine forming, sintering and hot working together, so as to directly obtain a drill product with better mechanical properties. The second process of titanium alloy bar is to form titanium and titanium alloy powder. After sintering, the prepared sintered blank is subjected to hot extrusion (for Ti-32Mo alloy, the temperature is 1000-1100 deg C) to obtain the performance of the titanium alloy product. Effect of extrudate ratio on the properties of titanium. It can be seen from the table that a titanium material with a theoretical density of 98.6% -99.1% can be obtained. The third process of titanium alloy bar is the extrusion process of filling blank,Titanium 6Al4V wire, which is an important method that can be used to make products with complex sections. The process includes the following steps: preparing sheathing cavity, determining the size of the cavity according to the required final product size and extrusion coefficient; sheathing. Filling the powder into the cavity and vibrating and compacting; evacuating, exhausting and sealing the sheath; extruding at a certain temperature and extrusion ratio; and stripping the sheath.
