The TA Instruments DIL805A/D/T is a high-precision quenching dilatometer designed to measure dimensional changes in a sample during controlled thermal cycles. It features inductive heating, rapid gas quenching, and the capability to deform samples in both compression and tension under thermal exposure, enabling simulation of complex thermomechanical processing conditions.
This instrument is used to study phase transformations, thermal expansion, and deformation behavior in metals. It supports the development of continuous cooling transformation (CCT) and time-temperature-transformation (TTT) diagrams, determination of critical transformation temperatures (e.g., Ac₁, Ac₃, Ms, Mf in steels and other ferrous alloys), as well as thermomechanical simulations. The deformation modules allow investigation of various phenomena such as hot formability, creep, stress relaxation, and strain-induced transformations.
Users benefit from precise, high-resolution data on how materials respond to heating, cooling, and mechanical loads, enabling the accurate prediction of microstructure evolution, material properties, and ultimately, material performance for a given application. This supports improved alloy design, process optimization, and reduced trial-and-error in product development, which can be very costly and time-consuming.
