Electromechanical Creep Testing Machine

The Electromechanical Creep Testing Machine is a computer-controlled testing system driven by a servo motor and designed for long-duration mechanical performance testing under controlled loading conditions. It is mainly used to evaluate the creep and stress-rupture behavior of high-temperature alloys, titanium alloys, ferrous metals, and non-ferrous metals. Depending on the selected fixtures and environmental accessories, the system can also perform stress relaxation, high-temperature short-time tensile, cyclic loading, and low-cycle fatigue-related tests.

Its modular structure allows the machine to be configured with different grips, extensometers, furnaces, vacuum systems, and inert-gas chambers for laboratory R&D, production inspection, and quality control.

Application

The Electromechanical Creep Testing Machine is suitable for:

(1) High-Temperature Alloy Testing: Evaluating creep and long-term deformation behavior of nickel-based and other high-temperature alloys.

(2) Titanium Alloy Testing: Studying the mechanical stability of titanium alloys under sustained loading and elevated temperatures.

(3) Metal Materials Research: Testing ferrous and non-ferrous metals for creep, stress rupture, and stress relaxation characteristics.

(4) Aerospace Materials: Evaluating materials and components used in aircraft engines and other high-temperature aerospace applications.

(5) Energy Industry: Supporting material evaluation for power-generation and other high-temperature service environments.

(6) Automotive Engineering: Testing metallic materials and components subjected to long-term mechanical or thermal loads.

(7) Materials Science and Engineering: Supporting research into deformation mechanisms and long-term material behavior.
