Description
| - The ever increasing requirements for mechanical properties of steels and the need for low purchasing cost compels manufacturers to develop new unconventional types of material microstructures that exhibit high strength and adequate ductility at the same time. In order to achieve such goals, one has to rely on unconventional heat treatment or thermomechanical treatment methods. One such method is Q-P processing that can be employed for treating cost-effective AHSS steels. In order to find the extent of changes in mechanical properties of microstructures produced by Q-P processing that take place either during the following warm forming or in the course of heating to moderately elevated temperatures, new measuring methods must be developed and deployed to quantify such changes precisely. The demand for measuring mechanical properties under conditions identical to those of a real-world manufacturing process is very common. A newly-developed testing method for measuring stress-strain curves with a short heating time in the order of seconds may serve as an example. It requires that a homogeneous microstructure is present throughout a testing body, and thus uniform temperature is achieved in the gauge part of the test bar. Dynamic tension test at a strain rate of 30 s-1 was performed at these conditions. This method has a distinct feature in that the measuring system consists of a highly dynamic testing device, accurate dynamic heating equipment, a set of strain gauges and a system of optical detectors. Under the above conditions, specimens of high-strength low-alloyed steel were tested in three different states: as-hot rolled condition, Q-P-processed state and as-quenched and tempered. Dynamic properties of the material were measured at 25 °C and 425 °C.
