The bridgman technique

網頁The Bridgman method is characterized by the radiation heating and cooling of the ceramic mold and casting (Figure 11.2 (a) ). Initially, it was used only for a directional solidification of the castings on the laboratory scale. 網頁2014年12月1日 · The Bridgman technique has evolved over the years, and an improved version of it was introduced by Stockbarger [5]. A multizone furnace was developed which led to more advanced furnaces. In this furnace, which was first built by Mellen [6], the axial temperature is controlled through local heaters separated by insulating, hollow, cylindrical …
