Initial grain
The influences of initial grain size (IGS) with 20 µm and 50 µm on the hot flow behavior and microstructural changes of pure copper were investigated using hot compression tests at a temperature range of 623–1073 K and strain rate range of 0.001–0.1 s −1. Visa mer Figure 3 illustrates the true stress–strain curves of pure copper with two initial grain sizes of 20 µm and 50 µm in which the effect of friction has been applied according to reference [35]. It can be found from these … Visa mer The microstructures of deformed samples are extensively investigated with optical microscopy to analyze the microstructure evolutions of hot deformed pure copper after the hot compression test at all different conditions of … Visa mer The derivative of the true stress with respect to true strain yields the work hardening rate (θ) which indicates the amount of internal evolution of materials and is obtained as follows: Figure 5 shows the curves of \sigma − … Visa mer The microstructural investigations and stress–strain curve analyses were used to demonstrate kinetic DRX under different processing conditions … Visa mer Webb23 nov. 2024 · (A) Grain size variations as a function of annealing temperature for three samples with initial average grain sizes of 50 nm, 25 nm, and 10 nm, respectively.

WebbRecrystallization is defined as the process in which grains of a crystal structure come in a new structure or new crystal shape. A precise definition of recrystallization is difficult to state as the process is strongly related to several other processes, most notably recoveryand grain growth. thermomix bircher müsliDynamic recrystallization (DRX) is a type of recrystallization process, found within the fields of metallurgy and geology. In dynamic recrystallization, as opposed to static recrystallization, the nucleation and growth of new grains occurs during deformation rather than afterwards as part of a separate heat treatment. The reduction of grain size increases the risk of grain boundary sliding at elevated temperatures, while also decreasing dislocation mobility within the material.
