Experimental device for thermodynamic properties of al-based binary intermetallic compounds

Abstract

The invention relates to an Al-based binary intermetallic compound thermodynamic property experimental device and effectively solves the problems that an existing experimental device is too large in size, needs a plurality of devices, is complex in operation and inconvenient to use and cannot perform corresponding experimental environment change according to different requirements. The solution isthat the device comprises a thermal insulation shell, an inner shell and a test block. A low-temperature plate is connected in the inner shell in a front-back sliding manner. A high-temperature plateis arranged above the low-temperature plate. Lifting supporting plates are in contact connection with the lower ends of the left and right sides of the high-temperature plate. The lifting supportingplates are connected with lifting racks slidably connected to the left outer side wall and the right outer side wall of the inner shell. The two lifting racks are both meshed with driving gears rotationally connected to the left side wall and the right side wall of the inner shell, the left side driving gear is fixedly connected with a rocking handle wheel rotationally connected to the side wall of the heat preservation shell, temperature sensors are fixedly connected to the lower end face of the high-temperature plate and the upper end face of the low-temperature plate, and the temperature sensors are connected with a control module fixedly connected to the heat preservation shell. The structure is simple and stable, and practicability is high.

Description

technical field [0001] The invention relates to the technical field of thermodynamic performance experiments, in particular to an experimental device for the thermodynamic performance of Al-based binary intermetallic compounds. Background technique [0002] The so-called intermetallic compound is the compound formed by metal and metal or metal and nonmetal (such as H, B, N, S, P, C, Si, etc.). The intermetallic compound has a different crystal structure and atomic structure from the original metal. , can form a new ordered superlattice structure, which has many distinctive properties and is different from the currently widely used metals or alloys. In recent decades, it has developed rapidly, and its application fields are gradually expanding, which makes it urgent to study the thermodynamic properties of intermetallic compounds. [0003] The research on the thermodynamic properties of intermetallic compounds mainly includes the research on their temperature, volume, therma...
