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 …

網頁The thin-walled airfoil areas of as-cast single-crystalline turbine blades made of CMSX-4 superalloy were studied. The blades were produced by the industrial Bridgman technique at withdrawal rates of 2, 3 and 4 mm/min. The angle between the [001] crystallographic direction and blade axis, related to the primary orientation, was defined by the Ω … 網頁2009年1月20日 · Knowing the primary solidification field, we have performed the vertical Bridgman growth using the starting liquid composition of Ba 15 Fe 42.5 As 42.5.
