引言压铸这一术语表示对熔融金属加压并使其凝固的各个过程。这一定义涉及的范围很广,包括生产接近网状铸件(有些铸件显示出晶粒的流向)和生产等轴锭的方法。本文只涉及后一种方法。为方便起见,把压铸叫做“加压结晶”。用加压结晶方法铸造出铸锭,以便得到压力、浇注温度和铸模温度对铸锭机械性能影响的再现性和定量的数据。 Introduction The term die casting refers to the various processes that pressurize and solidify molten metal. This definition covers a wide range of topics, including the production of methods close to mesh castings (some castings show the flow of grains) and the production of equiaxed ingots. This article only covers the latter method. For convenience, die-casting is called “pressure crystallization.” The ingot was cast by pressurized crystallization to obtain reproducible and quantitative data on the effects of pressure, pouring temperature and casting temperature on ingot mechanical properties.
