Superplastic tensile test was performed on a β-rich α+β titanium alloy (SP700 alloy) sheet in the temperature range of 740–800 °C and strain rate 1 × 10−4-1 10−2 s−1. The effects deformation parameters flow curves, sensitivity (m-value), thermal activation energy (Q-value) microstructural characteristics were investigated to elucidate mechanism. results showed that examined SP700 exhibited excellent superplasticity with fracture elongation up approximately 1800% deformed at 760 10−3 s−1,...
High strength β titanium alloys are widely used in large load bearing components the aerospace field. At present, parts generally formed by die forging. Different initial microstructures and deformation process parameters will significantly affect flow behavior. To precisely control microstructures, researchers have conducted many studies to analyze microstructure evolution law mechanism during hot compression. This review focuses on of high deformation, including dynamic recrystallization...
Due to the development of petroleum industry, more severe mining conditions put forward higher corrosion resistance requirements for materials. In this paper, and behavior four TC4-xNi-yNb (x, y = 0, 0.5) alloys were investigated in a 1 mol/L HCl solution through microscopic characterization, electrochemical tests weight loss testing. The results demonstrated that addition Ni Nb elements could improve TC4 alloy varying degrees. niobium formed oxide passive film, while nickel thickened film...
The excellent recovery performance of TiNiFe shape memory alloy is closely related to the predeformation in martensitic state. Based on classical phenomenological constitutive model, relationship suitable for mechanical properties constructed by introducing plastic strain. Aiming at problems uneven size and difficulty characterizing stress strain state deformation ring parts after expansion deformation, finite element simulation model cryogenic temperature established using UMAT interface...
In order to accurately obtain the deformation characteristics and suitable thermal conditions of TA15N titanium alloy guide design process parameters, a Gleeble 1500D was used conduct hot compression tests on behavior deformed under condition strain rate 0.01–10 s−1 temperature 850–1090 °C. The constitutive equations for based Arrhenius formula were developed, reliability verified. A processing map established by using dynamic materials model (DMM). research results show that flow stress...
The properties and microstructure evolution of quaternary Cu-Ni-Co-Si alloys with different Ni/Co mass ratios were investigated. morphological characteristics the precipitates analyzed by using electron backscatter diffraction (EBSD), transmission microscopy (TEM) high-resolution (HRTEM). mechanical conductivity significantly improved after addition Co. grains presented an obvious growth trend increase in ratios, appropriate Co accelerated recrystallization process. δ-(Ni, Co)2Si phases...
