Explanation of the tough brittle transformation temperature test of Jinan impact test machine

Impact testing machineIt is used for impact performance testing and testing of materials. For most medium and low-strength steels, this material will produce catalytic phenomena and is often used for impact testing and testing. Jinan Hengsi Shanda Instrument Co., Ltd. has made the following understanding of this impact testing method:

The temperature at which the toughness state of a metal transitions to a brittle state is called the toughness and brittle transition temperature, expressed in Tk. The tough and brittle transition temperature of metal materials can be detected by high and low temperature impact testing machines. High and low temperaturesImpact testing machineThe impact test is carried out at a series of temperatures from low temperature to normal temperature, and the curve of impact work with temperature changes is measured, where the temperature at which the impact work suddenly drops is Tk. But in fact, the impact work continuously drops within a certain temperature range. At this time, according to experience, the temperature at which the impact work is reduced to a certain value is Tk. For example, for ship plate steel, the temperature at which the Champions impact power drops to 20.4Nm is Tk.
