Structure, phase composition, physical properties of quenched VT16 alloy

Abstract

Features of structural and phase composition, physical and mechanical properties formation of VT16 alloy during quenching from temperature range 700-875°C were determined. For the first time formation of athermal ω-phase during quenching of the VT16 alloy within initial (α+β)-structure was experimentally shown. According to the summarized XRD and TEM data diagram of volume fraction variation depending on quenching temperature was proposed. Minimum of yield strength in the certain quenching temperature range was confirmed to be connected with the behavior of martensitic β → α″-transformation during tensile testing. Fine correlation between the Young's Module and phase composition variation was shown.
