Ice recrystallization is of great importance to both fundamental research and practical applications, however understanding and controlling ice recrystallization processes remains challenging. Here, we report the discovery of an ion-specific effect on ice recrystallization. By simply changing the initial type and concentration of ions in an aqueous solution, the size of ice grains after recryst...

in the present study, the influence of annealing temperature on mechanical properties and the microstructure of a high manganese austenitic steel (fe-30mn-4al-4si-0.5c) was investigated. x-ray diffractometry, optical and scanning electron microscopy, hardness and tensile tests were used to analyze the relationship between mechanical properties and microstructure after annealing process. the res...

Focused Ion Beam (FIB) is one of the important machining techniques to fabricate diamond sensors/detectors used for drug analysis, chemical analysis and bio-sensing applications. In-depth understanding of the high energy collision process and the residual damage induced along the trace of gallium ion could undoubtedly facilitate the development and improvement of performance of such devices thr...

The current understanding of the fundamentals of recrystallization is summarized. This includes understanding the as-deformed state. Several aspects of recrystallization are described: nucleation and growth, the development of misorientation during deformation, continuous, dynamic, and geometric dynamic recrystallization, particle effects, and texture. This article is authored by the leading ex...

A concise and efficient one-pot synthesis of 3-functionalized 4-hydroxycoumarin derivatives via a three-component domino reaction of 4-hydroxycoumarin, phenylglyoxal and 3-arylaminocyclopent-2-enone or 4-arylaminofuran-2(5H)-one under catalyst-free and microwave irradiation conditions is described. This synthesis involves a group-assisted purification process, which avoids traditional recrystal...

Pressure-induced amorphization (PIA) and thermal-driven recrystallization have been observed in many crystalline materials. However, controllable switching between PIA and a metastable phase has not been described yet, due to the challenge to establish feasible switching methods to control the pressure and temperature precisely. Here, we demonstrate a reversible switching between PIA and therma...

Abstract. In the aerospace industry, turbine disk plays a crucial role. Controlling average grain size during hot forming of nickel-based superalloys such as Inconel 718 is critical for production. Recrystallization primarily responsible evolution microstructure process. current study, Finite Element Method (FEM) employed to assess an incremental rolling FEM simulations are used obtain temperat...
