There are many commonly used constitutive equations of metallic materials, including Power-Law model, Zerilli-Arstrong model, Johnson-Cook model and so on.

1. Data processing of tensile experiment. Figure 1 shows the stress-strain curve of static tensile test. As can be seen

Because the chromium white cast iron used in the experiment is brittle material and has not been heat treated, the

Impact toughness is an important index of large wear-resistant plate. It refers to the ability of material to absorb plastic

It can be seen from Figure 1 that compared with the normal pressure, the hardness of the alloy can be

Different from equilibrium solidification, the solidification process of alloy melt under pressure is controlled by nucleation and subsequent crystal growth.

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,
