Argon-shielded hot pressing of titanium alloy (Ti6Al4V) powders.

The paper presents the method of the argon - shielded hot pressing of titanium alloy (Ti6A14V) powder (used in medical industry). The powders produced in the GA (gas atomization) process and in the HDH (hydride - dehydride) process were used in the experiments. A pressing process was conducted at a temperature of 800-850 degrees C for different lengths of time. An unoxidized sintered material, nearly as dense as a solid material and having a lamellar structure (alpha+beta), was obtained from the titanium alloy powder produced in the HDH process.
