Researchers were able to investigate the impact that rare earth alloys have on the microstructure as well as the properties of zinc alloy die-casting by making modifications to the process of zinc alloy die-casting. The findings were presented in the section that came before this one. Because of this, an efficient method for further enhancing the mechanical properties of die-cast zinc alloys as well as their resistance to intergranular lost wax casting corrosion was discovered as a result of the research that was conducted. Because of this, manufacturers all over the world, including Yuge, use zinc that has a high purity and is low in impurities. Additionally, they exercise very stringent control over the chemical composition of die-cast zinc alloys.

Die-cast zinc alloys will need to have their metallographic structures and mechanical properties determined in order for this experiment to be successful. The experiment will focus on determining the effect that a rare earth modification treatment has on these aspects of the alloys. The procedure that will be followed during the exam

The following materials were utilized at various points throughout the course of the experiment: a No. 1 zinc ingot, a No. 1 electrolytic copper ingot, and a No. 1 aluminum ingot. During the course of the experiment, various pieces of smelting apparatus, including a graphite crucible and a 45 kW crucible resistance furnace, were put to use.73% 1.25%, Mg0.  The experiment is designed to investigate the influence that the incorporation of rare earth alloys has on the metallographic structure as well as the mechanical lost wax casting properties of alloys. The purpose of the experiment is to investigate the influence that the incorporation of rare earth alloys has on the properties of alloys.

When melting, this is the procedure that needs to be followed in order for it to be successful:First, heat the graphite crucible until it turns a dark red color. Next, place aluminum ingots and aluminum-copper master alloy inside of the crucible. Next, wait until some of the aluminum liquid appears inside of the crucible. Finally, remove the aluminum ingots and aluminum-copper master alloy from the crucible. During the very last stage of the process, a covering agent needs to be incorporated into the charge in such a way that it accounts for about 2% of the total weight.0. At a temperature of 550 degrees Celsius, the liquid will begin to melt. This temperature is the melting point. Die casting can be done on the ingots of zinc alloy that have been poured, after which the ingots can be used in the process. The following is a list of the effects that rare earths have on the microscopic box phase structure of die-cast zinc alloy, as determined by the outcomes of a number of different experiments and studies:

1) The influence that the casting procedure has on the structure

Aluminum is the primary component of hypoeutectic alloys and can be found in approximately 4% of die-cast hypoeutectic zinc alloys. Because of this, the eutectic region expands, and the overall structure gives off the impression of being more consistent and well-balanced as a consequence.

Because of the impact that rare earths have had on the material, numerous equiaxed phases and grain boundary corrosion-prone phases have gradually changed into eutectoid phases. This is a result of the effect that rare earths have had. Because of this, the conditions are created for the improvement of the mechanical properties of alloys, the reduction of the amount of intergranular corrosion, and the improvement of the material's resistance to the effects of aging. All of these benefits come about as a direct result of the process of aging. In addition, in order to acquire a deeper comprehension of the distribution of the primary elements in the alloy after it has been modified, it has been reached the conclusion that the ZnAl4-1 alloy has been modified. This conclusion was reached in order to acquire a more in-depth comprehension of the distribution of the primary elements in the alloy. This conclusion was arrived at in order to acquire a more in-depth comprehension of the manner in which the primary elements are distributed throughout the alloy.

2) The effect that the die casting process has on the underlying structure of the components that are produced

If we compare the structure of the ZnAl4-1 alloy die-casting after it has been modified to that of the ZnA14-1 alloy when it is either in its primary phase or its eutectic phase, we see that the ZnAl4-1 alloy's structure is more refined, diffuse, blunt, and uniform. It doesn't matter if the alloy is in its primary phase or its eutectic phase; this statement is always accurate. This is the case whether one examines the structure from the viewpoint of the primary phase or the eutectic phase. Neither perspective changes this fact. Shenzhen Yuge carried out the task of determining the mechanical characteristics of the alloy by employing the specimens that were outlined in JB3072-82. 

In addition, the temperature of the mold was managed in such a way that it remained within the same general range as the temperature of the die-casting process. This was done in order to ensure that the effects of the treatment involving the modification of rare earth elements were amplified to their full potential. At the same time, in order to Die Casting Simulation Software further confirm the reliability of the test, microcomputer statistics were used to sort out the test data obtained under different conditions for the unmodified ZnAl4-1 alloy and the modified ZnAl4-1 alloy.

This was done in order to compare the results of the two types of ZnAl4-1 alloy. This was done so that the outcomes of the two distinct varieties of ZnAl4-1 alloy could be contrasted Die Casting Simulation Software and compared with one another.

In addition, the alloy solidification shrinkage was evaluated, and the findings demonstrated that the tensile strength and hardness of the ZnAl4-1 die-cast zinc alloy treated with rare earth modification increased by more than 10% in comparison to the ZnAl4-1 die-cast zinc alloy that did not include any modification at all. This was in comparison to the ZnAl4-1 die-cast zinc alloy that had been treated with no modification at all. 

This was in contrast to the ZnAl4-1 die-cast zinc alloy, which had absolutely no modifications of any kind. Additionally, there is an improvement in both the surface finish and the qualification rate. If between 0 and 1. If this is done, the structure can be optimized, the grains can be refined, impurities at the grain boundaries can be removed, and the damaging effects of impurity elements can be suppressed. All of these improvements are possible because of the grain boundaries. The former has a lower tendency for intergranular corrosion compared to a ZnAl4-1 die-cast zinc alloy that has not been modified by rare earth modification. This can be seen when comparing the two materials.
