DIL 805A Quenching Dilatometer – Measurement Principle
The DIL 805A/D is used to observe dimensional changes under extreme conditions of controlled heating and cooling. A solid or a hollow sample is inductively heated to a temperature plateau and is then continuously cooled with different (linear or exponential) rates.
The phase transformation occurring in the continuous cooling process or in the isothermal plateau (which may also be a multi-step transition) is indicated by the measured change of length. An array of cooling curves represent a continuous or an isothermal TTT diagram (Time-Temperature- Transformation diagram).
The beginning and end of the transformation indicate the alloy phase boundaries, e.g. ferrite, carbide, graphite, pearlite, bainite, martensite or other eutectoid phase batches.
Dynamic Systems Inc. (DSI), Gleeble 3800 system
Direct Resistance Heating (Joule Heating): The system passes high current at low voltage directly through the specimen. This method allows for extremely fast heating rates up to 10,000°C per second and produces uniform temperature throughout the specimen's cross-section.
Rapid Cooling and Quenching: The machine is equipped with water-cooled jaw carriers to allow fast cooling. An optional air/water spray quenching.
Servo-Hydraulic Mechanical System: A high-speed hydraulic system provides precise control of force and displacement. It can exert up to 20 tons in compression and 10 tons in tension, with stroke rates as fast as 2,000 mm/s.
Closed-Loop Feedback Control: The system uses thermocouples for temperature feedback, along with transducers to monitor force, displacement, and strain.
Atmospheric Control: The tests are conducted inside a sealed chamber, which can be filled with argon/nitrogen or evacuated to create a vacuum to prevent oxidation during high-temperature testing.
Sample Preparation, User Instructions and Precautionary Measures
- The sample should be free from rust.
