摘要： The present invention relates to a method for manufacturing a tube-type spray formed product and, in particular, to a method for manufacturing a tube-type spray formed product without using a core. The present invention provides a method for manufacturing a tube-type spray formed product in which a tube-type spray formed product is formed by spraying droplets through an atomizer installed at the position separated from the center portion of a rotating plate as much as the droplets should not sprayed on the center portion of the rotating plate.

摘要： A process for manufacturing an Al—Si alloy for use in a vehicle propeller shaft is provided. The Al—Si alloy manufacturing process includes the steps of heating and melting Al—Si alloy where Si contains 13-40 weight percentage (wt %) of the whole alloy, to thereby prepare melt, maintaining the melt at 700-900° C. and then spraying an high pressure inert gas to the melt and rapidly solidifying the same to thereby obtain a forming body, and extruding the forming body at 400-550° C. The physical properties of the Al—Si alloy manufactured by a spray forming process is at least similar to that of the vehicle propeller shafts which have been already known, and also spotlighted as new alloy compositions which can replace the conventional propeller shaft material.
