Prediction of Mechanical Properties for Pseudo-α-Titanium Alloy Forgings at Room and Elevated Temperatures
Abstract—The influence of compositional variations of the pseudo-α VT18U alloy on the mechanical properties of forgings after standard annealing is investigated. An increase in the degree of alloying (expressed in terms of aluminum and molybdenum equivalents) is shown to enhance the strength properties while decreasing the ductility and impact toughness of the alloy. A regression model is developed to predict the ultimate tensile strength using the chemical composition of the VT18U alloy forgings after conventional annealing. A predictive model is developed to estimate the ultimate tensile strength of VT18U semifinished products at operating temperatures up to 600°C using room-temperature data.
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.
