Summary: In October 2022, the “State Key Laboratory of Traction Power” at Southwest Jiaotong University conducted experimental testing at the Shanghai Synchrotron Radiation Facility for a project titled “Development and Application Verification of an Ultra-Low-Temperature In-Situ Mechanical Loading Device for X-ray CT.” As the project team responsible for the device’s cryogenic control module, Congtical Technology participated throughout the entire testing process.

Congtical Technology has long been committed to the development and research of thermal analysis systems for various materials, including metals, and actively participates in collaborative research projects with universities.

In October 2022, the “State Key Laboratory of Traction Power” at Southwest Jiaotong University conducted experimental testing at the Shanghai Synchrotron Radiation Facility for a project titled “Development and Application Verification of an Ultra-Low-Temperature In-Situ Mechanical Loading Device for X-ray CT.” As the project team responsible for the device’s cryogenic control module, Zhongguang Technology participated throughout the entire testing process.

During the testing process, the Chongguang cryogenic thermal‑mechanical stage simulated an ultra‑low‑temperature sample‑testing environment and, using the WinTemp temperature controller, delivered precise temperature regulation, thereby providing both hardware and software support for acquiring data on the mechanical properties and texture‑induced deformation of the material (aeronautical aluminum) under ultra‑low‑temperature conditions.

The cryogenic thermal‑mechanical stage developed by Congtical Technology serves as a low‑temperature testing module for in‑situ mechanical loading at ultralow temperatures. It employs liquid nitrogen and liquid helium refrigeration combined with resistive heating, and utilizes the company’s proprietary temperature‑control software (WinTemp) to achieve precise temperature regulation, enabling the measurement of material mechanical properties and structural deformation across a temperature range from room temperature down to –220°C.

The thermal‑stage temperature‑control software allows users to program up to 40 temperature profiles, enabling precise control of the temperatures required for deformation. #2 The thermal stage’s nitrogen‑reflux de‑fogging technology and transparent viewing window facilitate real-time monitoring of materials during low‑temperature deformation. #3 With industry‑leading low‑temperature control capability—down to −220°C—the device delivers superior performance and is highly compatible with most in‑situ tensile testing systems available on the market.

This test demonstrates that Congtical Technology ’s low-temperature thermal‑mechanical stage is capable of evaluating the mechanical properties and structural deformation of specimens under complex temperature‑varying conditions, and can effectively guide the in-service performance of materials in such environments.
Wuhan Congtical Technology Co., Ltd. is committed to building a high-tech instrument company that is focused, professional, and innovative. This project represents a pivotal step in Chongguang’s push into the ultra‑low temperature field, as well as an important milestone on the path toward even greater heights and broader horizons.
