The DIL805 Series  comprises of four models: DIL 805L, DIL 805A are quenching dilatometers, DIL 805A/D is a quenching with the capability to deform the specimen by compression, and DIL 805A/D/T that can also stretch it in tension mode.

All four instruments are fully automated, self-contained units used to measure dimensional changes under extreme conditions of controlled heating and cooling.

In the quenching mode the sample, solid or hollow, is inductively heated to a temperature plateau and is then cooled at an user-defined (linear or exponential) cooling rate. The phase transformation occurring in the continous cooling process or in the isothermal dwell, with or without compression/tensile stress, is indicated by the measured change in length. An array of cooling or isothermal curves represents a continous-cooling-transformation (CCT) diagram or an isothermal time-temperature-transformation (TTT) diagram, respectively.  DIL 805A represents today the benchmark for determining these dimensional changes and phase transitions. Operating from -160°C up to 1500°C (in two different furnace configurations) with heating rates of up to 4000°C/s and cooling rates of 2500°C/s, can closely simulate the material response for any production or heat treatment process.

The DIL 805A/D, on top of the quenching mode, is distinguished by its capability to deform the specimen with controlled deformation rates of of 0.01 to 200 mm/s. Used to optimize steel processes like hot or cold rolling, DIL 805A/D allows to develop time-temperature-transformation diagrams after deformation (DTTT) and is also used to examine creep and relaxation processes.

DIL 805A/D/T further extends the capabilities to alternate tensile and compressive loading to emulate mill processing.  Moreover, tensile loading to fracture lends additional information about material’s final performance and allows to generate true-stress  vs true-strain or stress/strain cycling plots.

DIL 805系列共包括四种型号：DIL 805，DIL 805A属于淬火热膨胀仪，DIL 805 A/D是具有压缩样品变形能力的淬火热膨胀仪，DIL 805 A/D/T还可扩展为拉伸模式。

所有者四种仪器都是完全自动化的、独立的操作单元，用于测量在极端条件下控制加热和冷却的尺寸变化。

在淬火模式下，空心或者实心的样品感应加热到一定的温度，然后以用户自定义的线性或直属的速率进行冷却。所测得的长度的变化表示在联系冷却过程或者等温条件下相变。一组冷却和等温曲线分别表示连续冷却转变CCT图和等温转变TTT图。DIL 805A淬火热膨胀仪是测定需要 严格的温度控制的钢合金尺寸变化和相变的新基准技术。可以在温度-160℃~1500℃、加热速率高达4000K/s、冷却速率超过2500K/s的条件下，进行用于生产或热处理的材料反应的模拟。

DIL 805 A/D采用顶部淬火模式，按照0.01到 200 mm/s的控制变形率下样品变形的能力来区分。用于优化钢铁如热轧或冷轧过程，DIL 805 A/D可以形成变形后DTTT图，也可以用来检查蠕变和弛豫过程。

DIL 805 A/D/T拉伸装置使仪器的功能进一步扩展到交变拉伸和压缩载荷。拉伸负载至断裂提供了材料 终性能的其他信息。这些数据被用来生成真实应力与真实应变或应力/应变循环曲线。
