What Is Semi-Solid Technology? Semi-solid technology refers to the use of heating materials to a semi-solid state to form a semi-solid structure in which the solid phase and the liquid phase are uniformly mixed. The solid phase rate is controlled by adjusting the heating temperature and time, and processing is performed in this state. Methods.…
Semi-Solid Deformation Theory 1. Dendritic stirring fracture theory The core of the semi-solid billet is to generate non-dendritic equiaxed crystals, and the material is stirred in a semi-solid state. During the stirring process, the stirring force and speed are increased, and the shear force of the crystal grains is The impact from the liquid will…
Mechanical Stirring Method And Electromagnetic Stirring Method 1.Mechanical stirring method The mechanical stirring method is the oldest and simple stirring method. It is different from the electromagnetic stirring method in that the stirring function is realized by the rotation of the blade or the stirring rod. The principle of forming the non-dendritic crystal is similar…
Microforming Process System Like the traditional forming process, the micro-forming process system is composed of four parts: material, forming process, tooling, and equipment (including tooling). In the micro-forming process, it is also necessary to consider the design of the mold, the optimization of the process parameters, the wear and treatment of the material, etc., but…
Micro-Molding Materials And Micro-Mold Manufacturing At micro-dimensions, various properties of the material have changed, and theoretical models at the macroscopic level can no longer be used to explain changes in materials during micro-forming. Therefore, experiments are needed to study the effects of material grain, surface grain and internal grain size, and material anisotropy during microforming,…
