Because of its high tensile strength and creep resistance, commercially pure titanium can remain stable at temperatures up to approximately 572°F. Compared to other metals, such as aluminum, titanium has low thermal conductivity, which can result in excessive heat build-up. Titanium is not soluble in water, and its hydrogen solubility ...
Thermal conductivity of Titanium is 21.9 W/ (m·K). The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity, k (or λ), measured in W/m.K. It is a measure of a substance's ability to transfer heat through a material by conduction. Note that Fourier's law applies for all matter ...

Constant feed – Titanium is prone to work hardening, namely, as the material is cut it becomes harder and therefore even more abrasive to tooling. A constant feed ensures that cutting work-hardened material is kept to an absolute minimum. Increased feed rate – If the machine allows, increasing the feed rate means that the tool spends less ...

The build chamber of the A2X is specifically designed to withstand extremely high process temperatures over 1,100° C. Building at elevated temperatures eliminates residual stress and ensures superior material properties. This opens the door to unique possibilities for additively manufacturing crack-prone materials, such as titanium-aluminide.
Top tips when machining titanium alloys: Due to the extremely low thermal conductivity, the use of high-pressure emulsion is advised. Cutting speeds depend on strategy but are typically relatively low and vary from 50 m/min (conventional) to 150 m/min (high-speed or advanced roughing). Positive geometries with tough cutting edges are …

Additional pictures for the melting of this sample can be seen in Figure 6.2.
Compared to selective laser melting, EBM machines use coarser powders and thicker layers on account of the larger size of electron beams. This limits the degree of detail that you can recreate thru EBM. It also means that metal parts made from EBM tend to come out with rougher surfaces and will require more thorough post-processing to …
