摘要

摘要：对VT8-1合金（Ti-Al-Mo-Zr-Sn-Si系）在20℃、900 ~ 1000 MPa的应力条件下进行了接近该合金屈服强度和极限抗拉强度的拉伸蠕变试验。发现断裂核是几乎垂直于加载轴的脆性面。利用透射电镜和扫描电镜的综合研究结果表明，脆性裂纹在（0001）平面上发展。

Fracture of a VT8-1 Titanium Alloy during Cold Creep

Abstract—A VT8-1 alloy (Ti–Al–Mo–Zr–Sn–Si system) is subjected to tensile creep tests at 20°C and stresses of 900–1000 MPa, which are close to the yield strength and the ultimate tensile strength of the alloy. Fracture nuclei are found to be brittle facets oriented almost perpendicular to the loading axis. The results of a comprehensive study using transmission and scanning electron microscopy demonstrate that brittle cracks develop in the (0001) plane.

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.
