QUENCHING DILATOMETRY

Quenching and Deformation Dilatometer In the processing of metal alloys, the quenching rate, isothermal dwell times, and deformation cycles dictate the final crystalline structure and resultant physical properties. These microstructural changes may be observed through direct process simulation with real-time monitoring of dimensional change, which reflect phase transitions. The measurement of distinct alloy compositions allows the creation of, among other things, Time-Temperature Transformation diagrams (TTT) and Continuous-Cooling Transformation diagrams (CCT), which are critical for process...

Sub-zero Module In many cases, the martensitic finish temperature, Mf, of a steel lies well below room Thermocouple Placement Apparatus temperature. This add-on module operates from -160˚C to 1300˚C, with attainable Precise temperature control requires temperature monitoring adjacent to the sample. controlled quenching rates in excess of 4000 °C/sec, and allows for the complete The easy-to-use thermocouple placement device reproducibly spot welds up to three characterization of the austenite to martensite transformation. This unique quenching thermocouples directly onto the sample for temperature...

Force Deformation Force Deformation the resultant force required to achieve this. In this high speed test run, a deformation rate Steel Phase Transformation of 10 mm/s is used for a maximum displacement of 5 mm (Strain 0.50). The force exerted by the hydraulic ram is closely monitored, and both data sets can be used to plot the true stress vs. true strain curve of the material. phases of steel are especially clear when measured by the DIL 805A Quenching Dilatometer, and the temperatures at which they occur are critical in the construction of the TTT and CCT diagrams. In this example, the first...
