The present invention provides an automated device for degassing and/or foaming of metals and their alloys and process thereof. Said automated device for degassing and/or foaming of molten metals and their alloys and a process facilitates in controlled degassing and/or foaming of molten metals and thereby increases tensile strength, impact strength, hardness, malleability, corrosion resistance, conductivity of metals and their alloys and further eliminates the use of harmful chemicals and injectable gases in degasification of metal and alloys. Present automated device mainly comprises of plurality of sonic generator 1, controller 2, first assembly 3, second assembly 4, third assembly 5, fourth assembly 6. Said process comprises of steps including; 1. Selecting the mode of operation and setting parameters; 2. Activating said assemblies and facilitating Formation of ultrasonic cavitation in metal and their alloys; 3. Degassing of the molten metal and their alloys due to formation of micro bubbles.

A highly-productive method for manufacturing a metal foam, capable of easily manufacturing a molded article having a desired shape is provided. A method for manufacturing a metal foam includes dissolving hydrogen in a mixture containing a molten metal and a thickener, and thereby manufacturing a precursor in which an amount of solid-soluted hydrogen in the metal is saturated, charging the precursor into a mold, and solidifying the precursor charged into the mold under a reduced-pressure atmosphere, or solidifying the precursor charged into the mold and then heating the solidified precursor under a reduced-pressure atmosphere.

An implant for in-vivo implantation which comprises an assembly of two or more constructive elements (3,4) which are movable relative to each other. Each constructive element (3,4) is partly or completely porous and comprises a porous part (5,6) with a matrix (7,8) of open cells (51,61). A first matrix (7) of the first element (3) comprises a first overlapping part (50) with a form-closed connection to a second overlapping part (60) of a second matrix (8) of the second of the constructive elements (4) through which the first overlapping part extends. The overlapping parts (50,60) are movable relative to each other to change a combined shape of the overlapping parts.

Structural metal-matrix composites (MMC) comprising a foam matrix material infiltrated with a binder material, where the binder material binds the foam matrix material to a structural element of a tool, thereby enhancing three-dimensional reinforcement of the tool. In some instances, the structural element is a portion of a wellbore tool or a bit body, such that portions of such tools or bit bodies are composed of the structural MMC. The foam matrix material may be composed of a metallic foam, a ceramic foam, and any combination thereof.
