hdh titanium powder

LDED-HDH-RF is a method that is used to produce a sintered compact of an alloy consisting of Ti-6%Al-7%Nb. The procedure involves the scavenging of oxygen by the compound LaB6 and the sintering of hdh titanium powder. The procedure, as well as certain conclusions, will be discussed in this article.


During the ball indentation process, X-ray Micro Tomography (XMT) was utilized to demonstrate the interaction of titanium powder compacts. In addition, an energy-dispersive X-ray (EDX) method was applied to determine the elemental makeup of the powders. This work was made possible thanks to the "863" High Technology and Development Project.

An induction coil with a circular structure imprinted the spherical titanium powders with its pattern. To generate a suitable magnetic field, several windings were utilized. After that, the powders were carved out and etched to reveal the grain structure.

The ability of the powder to produce a somewhat weak but detectable magnetic field is by far the most intriguing property it possesses. When combined with the spheroidization process, this technique results in the production of a powder that has a high density that is loosely packed.

Although the spherical shape of the powder is advantageous, the actual size of the particle is far less than its appearance would suggest. Because of this, it is not unusual for the particle to be reassembled with a bigger diameter than it originally had. Within the scope of this investigation, the powder particles with the smallest sizes measured less than 75 millimeters.

Using HDH titanium powder metallurgy in additive manufacturing has been the subject of a number of investigations that have been carried out. The results of these experiments indicate that HDH Ti particles possess certain mechanical qualities that are advantageous to the process. These characteristics include a high strength, a low rate of work hardening, and a low elongation over length. However, the HDH Ti powder has a few limitations, including low flowability and contamination during the milling process. These shortcomings make the powder less desirable.

In addition to that, the surface of the titanium powder is quite smooth. Producing the powder in this manner results in lower production costs. However, it is essential to keep in mind that the surface treatment alone is not sufficient to generate a shape that is perfectly spherical. In order to get a spherical shape, an additional spheroidization step needs to be carried out.

In order to analyze the qualities of HDH Ti powder, a battery of chemical and morphological experiments was carried out. Analyses such as elemental analysis, solid state infrared absorption, laser diffraction, scanning electron microscopy (SEM), and phase analysis were carried out. In addition to this, an X-ray fluorescence study was carried out in order to determine the amount of silicon present in the HDH Ti powder.
