Melt extraction of ceramics

A free flowing stream of molten metal is motioned to encounter a higher diameter and faster moving free flowing stream of a cooling liquid, such encounter resulting in the splitting of the molten metal into droplets. The droplets in contact with the cooling liquid and entrained therewith are allowed to solidify by cooling; optionally they may undergo further splitting before complete solidification by impingement upon a target arranged to intercept the course of the cooling stream.

Production of particulate or powdered metals and alloys

A process for manufacturing a component from a mechanically unstable .beta.-titanium alloy which exhibits 3 shape-related memory effects which all differ from one another: a one-way effect, a two-way effect (resembling a bi-metal), this effect being virtually hysteresis-free but occurring continuously over a wide phase-transformation temperature range, and an irreversible effect, which is isothermal. Utilization of the effects in thermal triggering elements (electrical switches) as well as in fixed or detachable connecting elements for components.

Brittle Ni/Ti memory alloys containing copper can be transformed, from the cast condition, into semifinished product which is suitable for further processing, by a process in which a cast bar is homogenized, a little below the solidus line, and is then isothermally extruded in the temperature range from 700.degree. to 850.degree. C.
