Method for preparing a metallic article having an other additive constituent, without any melting
A method for preparing an article of a base metal alloyed with an alloying element includes the steps of preparing a compound mixture by the steps of providing a chemically reducible nonmetallic base-metal precursor compound of a base metal, providing a chemically reducible nonmetallic alloying-element precursor compound of an alloying element, and thereafter mixing the base-metal precursor compound and the alloying-element precursor compound to form a compound mixture. The compound mixture is thereafter reduced to a metallic alloy, without melting the metallic alloy. The step of preparing or the step of chemically reducing includes the step of adding an other additive constituent. The metallic alloy is thereafter consolidated to produce a consolidated metallic article, without melting the metallic alloy and without melting the consolidated metallic article.
Functionalized magnetic nanoparticles and a method for preparation thereof
The present disclosure relates to a method for manufacturing a covalently functionalized coated magnetic nanoparticle and to said particles and uses thereof. The preparation method includes forming a shell of a hydrophilic polymer coating layer on top of a magnetic metal core coated with a carbon coating.

Titanium alloy
A titanium base alloy powder is formed by subsurface reduction of a chloride vapor with a molten alkali metal or molten alkaline earth metal to form reaction products comprising pre-alloy particles and a salt of the alkali metal or the alkaline earth metal. A majority of the pre-alloy particles have a composition of at least 50% by weight of titanium, about 5.38% to 6.95% by weight of aluminum, and about 3% to 5% by weight of vanadium. The pre-alloy particles are recovered from the reaction products to produce a titanium base alloy powder containing less than about 200 ppm alkali or alkaline earth metal.
