Abstract—The causes of the technological brittleness of multicomponent copper–zinc alloys are investigated using complex LMtsAZhN brass (Zn–Cu–Mn–Al–Fe–Si–Ni) as an example. The relation of cracking of brasses to silicide-forming elements and lead is shown. The distribution and morphology of lead precipitates in destroyed blanks have been studied. The formation of metastable precipitates is shown to be caused by the redistribution of copper, aluminum, silicon, and phosphorus. The stoichiometry of silicides of various morphologies in the industrial batches of brass blanks is determined. The conditions for eliminating the technological brittleness of complex copper–zinc alloys are formulated.
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.
