PRODUCTION OF CAST PRODUCTS WITH CONTROLLED DENSITY BY CONTROLLING GAS CONCENTRATION IN A MATERIAL

摘要

A method for the production of cast products. The method is particulary directed to the production of porous metal products, such as titanium- or zirconium-containing porous metals, by controlling the concentration of gas in the material during melting and solidification of the material. The invention is also directed to products fabricated by such a method.
