“…Ni30 superalloy is a new solution-strengthened nickel-based superalloy, which has good high temperature strength, high temperature oxidation resistance, gas corrosion resistance and mechanical properties. It is used to manufacture core components with high high temperature corrosion resistance, such as aviation jet engine blades, industrial gas turbines, rockets and heat exchangers [1][2][3]. At present, the influence of solution aging treatment on the microstructure and mechanical properties of nickel-based superalloys at home and abroad mainly focuses on the best solution aging treatment process, recrystallization, grain growth behavior, precipitation and dissolution of strengthened phase, and the effect of aging treatment system [4,5] on alloy properties.…”

Using JMatPro numerical simulation to determine the range of process parameters, the solution aging treatment of Ni30 superalloy was carried out, and the influence of different solution treatment temperatures on the microstructure and hardness of the alloy was studied. The results show that with the increase of solution temperature, the grain grows rapidly, the grain growth process conforms to Arrhenius formula, and the activation energy Q of grain growth is about 74.33kJ/mol. The maximum hardness value of the sample is 41.80HRC after solution aging treatment at 980°C.

In this study, tensile tests for magnesium–manganese rare earth alloy (MnE21) were conducted with a WDW-300 high-temperature universal testing machine at different temperatures (300 °C~500 °C) and strain rates (1 × 10−4s−1~1 × 10−1s−1). The high temperature thermal deformation behavior, dynamic recrystallization, and texture of MnE21 magnesium alloy were analyzed by combining the constitutive equation, hot processing map, and electron backscatter diffraction (EBSD). The results show that the strain compensation equation can accurately predict the thermal deformation behavior. According to the hot processing map, the optimal processing regions were determined to be 350 °C, ε˙= 1 × 10−2s−1~ε˙= 1 × 10−4s−1, and 450–500 °C, ε ˙= 1 × 10−1s−1~ε˙= 1 × 10−4s−1. Based on the EBSD analysis, it was found that dynamic recrystallization of the alloy occurs above 350 °C, it was concluded that dynamic recrystallization was more adequate at 450 °C by analyzing the grain orientation and grain boundary difference orientation distribution. In addition, the texture index at different temperatures was also analyzed and it was found that the material showed a typical extrusion texture internally. During dynamic recrystallization, (01-11) [2-1-11], texture was produced.
