It has been proved that different types of carbides have different hardness. The purpose of different casting processes is to

Besides discussing the interface structure, which is the mechanism of atom stacking and crystal morphology, we also need to discuss

Crystal growth is a process in which the atoms in the liquid phase migrate and stack to the surface of

Because the composition of low chromium white cast iron alloy 1 is far away from eutectic point, the carbides are

In the solidification process of Hypoeutectic chromium white cast iron, the primary phase is austenite, the carbides in the solidification

The total amount of carbides, eutectic carbides and primary carbides in alloy 2 are shown in the figure. The content

In order to better compare the solidification structures of different sampling positions under different pressures, the solidification structures of top,

(1) Solidification structure of specimens at different positions under atmospheric pressure The solidification structure of alloy 2 under normal pressure

The results show that the pressure, fluidity and cooling rate of liquid metal at different positions are different during solidification.

The stability of solid-liquid interface affects the morphology of microstructure and determines the final properties of materials. The expression of

The relationship between pressure and solute diffusion coefficient can be described as follows Where: DP — solute diffusion coefficient under

Through the characterization and analysis of the morphology of the above hypoeutectic alloy 1 # eutectic structure, the eutectic morphology

Because the primary phase in the solidification structure of alloy 1 is austenite, the eutectic austenite in the divorced eutectic
