Quenching DIL – Steel rod – Thermal expansion / Deformation
Stainless steel – Thermal expansion / deformation – Quench cooling
The L78 Q/D is the ideal instrument for optimizing the quench rate after multi-step deformations. With these measurements the processing of steel can be simulated to control the crystalline structure and the physical properties. The quenching and deformation rate is very important for the properties of the end product and to optimize forging processes.
In this example, after the initial heating and resultant thermal expansion, the parcel of steel is held isothermally and goes through a series of 2 deformation steps: an initial 1mm deformation over a 10 s time period followed by a second 1 mm deformation over again 10 s time period. After the deformation steps the material is quenched and the contraction and phase transformation is measured. These data can be used for manufacturers to optimize their production processes for steels with the requested physical properties.
