This time let us tell you a story from far far away. Let’s go back in time on 1791 when William Gregor, in Cornwall discovered this chemical elemnt named Titanium by Martin Heinrich Klaproth for the Titans of Greek mythology.
In 1966, Nasa published a technical memorandum on Heat Treatment Of Titanium and Titanium Alloys
Two-phase titanium alloys constitute very important group of structural materials used in aerospace applications. Microstructure of these alloys can be varied significantly in the processes of plastic working and heat treatment allowing for fitting their mechanical properties including fatigue behaviour to the specific requirements.
We have lamellar, recrystalised and Bi-modal.
– Lamellar , ie with high tenacitià and resistance to the propagation of the defects but with poor ductility
– Recrystallised , with fairly good mechanical strength and good ductility
– Bi-modal , that is, with the best combination of mechanical properties
Before the heat treatment, Titanium must be perfeclty cleaned, degreased and dried in order to avoid its contamination that leads to poor final product properties.
This is the main reason we need in air or inert atmosphere furnaces for Titanium delivered by HTS, a leader company for high vacuum furnaces for heat and surface treatment of metal, braze welding and sintering, a furnace with cooling in a water bath for solubilization of titanium and aluminum. The heating chamber is placed in the upper part and has the door opening in two halves. The tub cooling water is positioned in the lower part and is positioned in the pit. The travel speed of the charge from the hot chamber to the cooling tank is the strategic characteristic for the treatment of titanium and aluminum.
