The hot deformation behavior and rolling based on the processing map of a nano-Y2O3 addition near-? titanium alloy were investigated. isothermal compression tests conducted at various temperatures (950?–1070 °C) strain rates (0.001–1 s?1), up to true 1.2. flow stress was strongly dependent temperature rate, decreasing with increased decreased rate. average activation energy 657.8 kJ/mol 405.9 i...

The inhomogeneous strain distribution introduced by the tensile deformation of pearlitic steel was visualized using digital image correlation method, and morphology cementite quantitatively evaluated. high near block boundaries. Within blocks, inhomogeneously distributed. ratio (Lcem/Lcol) length to colony size, which is related degree spheroidization, well correlated with average within coloni...

In this work, the mechanical behaviour and microstructure changes of AA-7075 alloy subjected to a repetitive-bending-under-tension (R-BUT) process were studied. R-BUT process, metallic strip undergoes repeated localised bending unbending. Load-displacement curves derived from tested samples displayed drastic increase in elongation failure as compared standard tensile tests. Additionally, result...

Laser powder bed fusion (LPBF) requires application of powders with specific characteristics. These are near-spherical shape particles, uniform elemental composition, typical particle size 5 – 70 µm, etc. Such produced by spheroidization methods. They have such disadvantages as high cost and sale only in large quantities. There publications describing LPBF powders, the methods, alternative to s...

Mg Cored wire method is a type of spheroidization treatment method. It has been introduced by many foundries from the viewpoints improving environment safety factory workers, automation and productivity. However, prediction residual content depends on experience because various factors complexly affect each other effects factor yield rate have not clarified theoretically.
