“…However, because of the high cost of raw materials, combined with the difficulty associated with forming and machining processes, several methods attempt to produce nearnet shape configurations of the desired components in an effort to eliminate or minimize metalworking. Particularly, powder metallurgy is one of the most promising alternatives to obtain titanium near-net parts [1][2][3].…”

“…The EDS analysis of this powder and the sample sintered did not show detectable contamination. Shaeffer et al [8] observed that TiH 2 can be easily converted to α Ti by heat treatments using high vacuum levels. This test was made to evaluate possible contamination and if the system of cleaning of the sample was efficient.…”

Several materials have been used as surgical implants since the 16th century. Materials can be implanted in the human body; however, the choice of the appropriate material is based on the required mechanical, physical, chemical, and biological properties. Until now two classes of metals namely stainless steel and cobalt-chromium-molybdenum alloys became known as materials for implant applications. They were considered suitable for surgical implant procedures but many researchers and surgeons were not completely satisfied with their performance. The main problem of the modern science is to find a material that perfectly restores tissues damaged after accidents or diseases. The trend of the current research in orthopedic prosthesis is based on the development of titanium alloys composed of non-toxic elements with low modulus of elasticity. Powder metallurgy techniques have beenused to produce controlled porous structures such as the porous coating applied for dental and orthopedic surgical implants which allows bone tissue grown within the implant surface, improving fixation. The development of porous metallic biomaterials associated with their biomedical applications is an important research area. To obtain a good one implant successful therapy the composition, size, form and topography of the alloys are extremely important.

“…Available literature related to the hydrogenation semiconductor capacitors, which realize a high electrical of pure Ta is limited to hydrogen embrittlement. This hydrogen-induced cracking recrystallized microstructure with a grain size of about 100 or pulverization is caused by hydrogen absorbtion, which m. Some of them were electropolished in a solution of 2.5 has been reported in Ti alloys, [4,5,6] rare-earth-transitionpct HF and 5.0 pct H 2 SO 4 in methanol at about 230 K, [18] metal magnets, [4,7] refractory alloys, [4,[8][9][10][11][12][13] and hydrogen which were supplied for microstructure observation. [1,2] In order to improve the pure Ta, it is necessary to understand the mechanism of electrical properties as a device, it is essential to fabricate hydrogen-induced cracking.…”
