摘　　要：受到测量设备的限制,金属材料高温凝固过程的相转变和转变量的定量研究很少涉足。该项研究开发了一种金属材料高温凝固相转变测量装置,在实验过程中为了使测量样品温度均匀,样品的质量控制在20 g左右;为确保金属材料融熔化,采用铂金电阻丝作为加热体进行加热;为了能够控制凝固过程液固相转变及其相转变比例,采取了凝固过程温度可控、冷速可控措施,并把冷至设定温度的样品在液氮或者冰盐水中快速冷却。通过对快速冷却得到的组织进行分析,可以实现凝固过程组织的定量分析并最终获得高温凝固相转变规律。The high temperature solidification phase transformation and amount of metal materials is seldom researched due to a lack of a corresponding experimental device.A kind of experimental device for measuring the phase transformation of peritectic reaction at high temperature was designed.In order to keep a uniform heating temperature of the samples,the amount of the samples was about 20 g.the platinum resistance wire was used as the heating body to melt the iron and steel materials.Some relative measures were taken to control the temperature and cooling rate to control the high temperature solidification phase transformation and the proportion.The samples at target temperature were quenched in liquid nitrogen or with ice salt water.Solidification phase transformation laws at the high temperature were obtained by the later microstructure quantitative analysis.
