ABSTRACT:
A pressure vessel of the present invention is such that at least part thereof comprises a metallic composite material40comprising alight metal41, which is turned into a matrix, and a plateshaped iron-basedmember42, which is buried in the light metal41, whose major component is iron, and which is provided with a large number of through holes penetrating the front and rear surfaces. By means of this construction, it is possible to provide a pressure vessel having a novel construction whose pressure resistance is enhanced without being accompanied by thickening, and a compressor being provided with a housing comprising the pressure vessel.Moreover, a casting process of the present invention is a casting process, which is suitable for producing cylinder blocks, and is characterized in that, in a casting mold80being provided with hollow portions (86, 87) forming a molding cavity surface84, and a pouring passage85which is communicated with the hollow portions, a substantially cylindrical iron-based member42having cut-offs45at the opened end portions is allocated so that the opened end portions are brought into contact with the molding cavity surface84and spaces86, 87are provided on the front- and rear-surface sides of the iron-based member42, and a light-metal molten metal41′ is filled into the entire hollow portions through the pouring passage85via the cut-offs45, thereby casting the light metal41around the iron-based-member42.
