Title: Plasma electron beam melting and casting method for al-containing intermetallic compound
Inventor: KURABE HEIJIRO
IPC: C22B9/22
Filed: 1988-12-23
Abstract: PURPOSE:To restrain vaporization of Al and to stably produce a Ti-Al intermetallic compound having the fixed composition by melting under gas atmosphere at the fixed pressure at the time of producing the Ti-Al intermetallic compound by melting a bar-like cast ingot of the specific component of Al and Ti with a plasma electron beam irradiation. CONSTITUTION:Coarse grain state Ti and Al are mixed at the fixed ratio and compressed and this compacting body 1 is charged into a crucible 3 and melted with irradiation of the beam 4 in a plasma electron beam furnace 2 to form the bar-like cast ingot 5. This bar-like cast ingot 5 is supported with a supported tool 6 and shifted toward lower part of the beam 4, melted and reacted and dripped into the water cooled steel-made mold 7 to form the columnar cast ingot 8 of Al-Ti intermetallic compound as the light wt., heat resistance material. In this case, flow rates of gas A for beam and inert gas B of Ar, etc., in the plasma electron beam furnace are adjusting and by holding the pressure of the atmosphere in the furnace to the fixed value, the vaporization of Al is restrained and the Al series intermetallic compound of Al-Ti, etc., is produced without changing the composition. This can be effectively utilized to generate the Al series intermetallic compound.
