Embodiment Construction

[0018] The transparent model alloy device comprises a quartz glass tube (10) containing the transparent model alloy succinonitrile, a temperature gradient platform and a detection system.

[0019] The temperature gradient platform is vertical, the upper heating platform is heated by a PTC heating module (3), and the lower cooling platform is cooled by a semiconductor refrigeration device (14); the temperature system adopts a Jackson-type temperature gradient platform to realize hot and cold platforms The distance between them can be adjusted arbitrarily, and the interval temperature has a linear relationship with the position change. The temperature of the hot stage and the cold stage is precisely controlled by using a super thermostat and a low-temperature thermostat, and the temperature in the quartz glass tube (10) is detected by a thermocouple (11). The temperature gradient hardly changes with the change of the moving speed of the sample. The PTC heating module (3) is pres...

Abstract

The invention relates to transparent model alloy equipment. It includes quartz glass cell containing transparent model alloy, temperature gradient platform and detection system. Its characters are: heating stage of temperature gradient platform use PTC calefaction module to warm, cooling stage use semiconductor refrigerator to cool, temperature can be accurately controlled, distance between heating stage and cooling stage can be adjusted arbitrarily and temperature difference is in direct proportion to distance between heating stage and cooling stage. Merits of the invention are: high precision; being able to measure flow field, temperature field and chroma field; butanedinitrile not being extruded under 90deg.C and ensuring photograph frame clearness in flight test.

Description

Technical field: [0001] The invention relates to a device for conducting material science simulation experiments, in particular to a device for space metal alloy experiments. Background technique: [0002] Under space microgravity conditions, it is possible to obtain homogeneous immiscible alloys because the influence of gravity is excluded. However, the solidification experiments of such alloys under microgravity conditions in recent years have not been satisfactory. It has been found that under the condition of space microgravity, the droplet migration phenomenon (Marangoni migration) caused by the surface tension gradient of the droplet and not related to gravity still causes two-phase separation in the solidified final tissue. Due to the high melting point and opaqueness of metal materials, the solidification process is invisible, and it is impossible to conduct real-time observation and quantitative theoretical analysis of the strong mechanical process of Marangoni conv...
