Abstract—The interaction between molten nickel and individual grain boundaries in tungsten is investigated. These boundaries are specially prepared and crystallographically characterized before the experiments. Nickel penetration is investigated in bicrystals with particular boundary types, as well as in single crystals and polycrystals of tungsten for comparison. The extent of nickel penetration depends on the structure of the grain boundaries. At certain boundaries, nickel forms segregations. However, at high-angle boundaries, nickel segregation induces brittle intergranular failure and promotes cleavage cracking.

钨与熔镍之间的相互作用

摘要：研究了熔镍与钨中单个晶界的相互作用。这些边界是在实验前专门制备并进行晶体学表征的。研究了镍在具有特定边界类型的双晶中的渗透，以及在钨的单晶和多晶中进行比较。镍的渗透程度取决于晶界的结构。在一定的边界上，镍形成偏析。然而，在高角度晶界处，镍偏析导致脆性晶间破坏，促进解理开裂。

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.
