  die casting
However, die casting has two significant disadvantages over wrought alloy sheets: it results in poorer mechanical properties and much rougher surfaces.
      
Most magnesium parts for automobiles are currently produced by die casting, which allows for complex geometries.
      
To understand and control the filling process for metals in high-pressure die casting and ingot casting, researchers have used new flow-simulation software for the modeling of mold filling.
      
This makes high-pressure die casting unique since the resulting refined microstructure provides excellent mechanical properties.
      
In developing alloys for high-pressure die casting, the peculiar aspects of the process must be considered.

This paper deals with the mechanism of forming the dross defect, which is shown after nitriding in the nodular cast iron crankshaft of the diesel locomotive, and its methods of prevention. By analysing the compositions of the drosses taken from the crankshaft, it has been found that this defect is mainly caused by the oxide dross, formed during the pouring process of the low pressure die casting. Based on the data measured in production,a hydrau- lic model is built to investigate the influence of the way of filling mould on the dross formation. It is found that "cold liquid metal"in the refractory tube and its turbulent flow within the mould is the main reason of the defect. Experiments indicate that using the "overflow chamber", which can equalize the temperature in the mould and skim off the early dross, is an effective way to prevent the defect.

本文研究内燃机车球墨铸铁曲轴中夹渣缺陷的形成机理及防止的方法。通过对曲轴中夹渣组成的分析,确定该缺陷主要是在低压铸造过程中所形成的氧化夹渣。在测定现场工艺参数的基础上,采用水模拟试验方法研究充型过程对夹渣形成的影响,发现开始于升液管内形成的“冷铁水” 及其随后的紊流流动是形成这种缺陷的主要原因。实验证明,使用“溢流室”改变型内温度竹市和撇除早期渣,是消除这种缺陷的有效方法。

Improved rheocast process was studied for performing the high quality of Al alloy casting made of the preparation of the metal slurries. The measures taken for reducing the porosity of die casting have been investigated. It was shown that the conventional diecasting is not to be compared with the rheocasting for ZL104 and ZL702 as well as other Al alloys. The hydrogen content may be much lowered, and the bulging surface on the casting may be much improved after heat treatment.

本文采用流变铸造方法制备铝合金浆料,并对其在压铸件中产生的气泡进行了研究。结果表明此种方法使压铸件中氢含量降低、气泡减少,再经热处理时铸件表面鼓泡现象显著改善。实践证明,采用流变铸造铝合金可明显提高铸件的质量。

The experimental results are shown that the casting quality by rheo-casting is superior to that of conventional die casting. By the use of combination of rheo-slurry (semi-solid aluminium alloy) with vortex stirring processes, many compositions of aluminium alloy with portionlate and fibrous nonmetals can be produced. Some of them, such as Al-graphite composite possess excelent antifriction and wear resistant properties, high damping rate and good machinability.

本文综述作者们在流变铸造及铝基复合材料方面的研究结果。流变铸造的铸件质量比普通压铸件好。采用流变料浆(半固态合金)与旋涡法搅拌工艺相结合,可方便地制备多种铝基复合材料。某些复合材料(例如A1-石墨)具有特殊的摩擦磨损性能,高的衰减率及良好的切削性能。
