Preparation of a Rolled Thin Sheet from a Molybdenum Single Crystal while Maintaining a Single-Crystal Structure
Manufacturing foundations for maintaining a single-crystal structure in rolled thin sheets (0.5 mm thick) prepared from a high-purity [110] molybdenum single crystal grown by electron-beam zone melting are reported. The sheets are manufactured from plate workpieces cut from the single crystal using cold rolling (350°C); a reduction per pass of 5, 10, and 15% to a total strain of 50–75%; and intermediate and final annealing. The maximum scatter of the [001] orientation in the rolled sheets is 3.42°; after final annealing, it is 2.64°. The substructure is studied, and the microhardnesses of the single-crystal plate workpieces (≈177 HV0.5), the final-thickness rolled sheets (≈199 HV0.5), and the sheets subjected to final annealing (≈190 HV0.5) are estimated.
期刊介绍：
Russian Metallurgy (Metally) publishes results of original experimental and theoretical research in the form of reviews and regular articles devoted to topical problems of metallurgy, physical metallurgy, and treatment of ferrous, nonferrous, rare, and other metals and alloys, intermetallic compounds, and metallic composite materials. The journal focuses on physicochemical properties of metallurgical materials (ores, slags, matters, and melts of metals and alloys); physicochemical processes (thermodynamics and kinetics of pyrometallurgical, hydrometallurgical, electrochemical, and other processes); theoretical metallurgy; metal forming; thermoplastic and thermochemical treatment; computation and experimental determination of phase diagrams and thermokinetic diagrams; mechanisms and kinetics of phase transitions in metallic materials; relations between the chemical composition, phase and structural states of materials and their physicochemical and service properties; interaction between metallic materials and external media; and effects of radiation on these materials.
