Abstract

The invention belongs to the technical field of material testing, and discloses a NiZn ferrite material thermal shock resistance evaluation method. According to the method, a NiZn ferrite material sample is heated to a certain temperature T1, thermal insulation is performed for a certain time, the material is quickly taken out and then is placed into a cooling medium T2, the residual strength is tested under different thermal shock temperature difference [delta]T through a three-point bending method, the [delta]T is equal to T1-T2, the relation curve between the residual strength [sigma] of the NiZn ferrite material sample and the thermal shock temperature difference [delta]T is obtained, and the thermal shock temperature difference corresponding to the sharply-reduced residual strength [sigma] is the critical thermal shock temperature difference [delta]Tc of the NiZn ferrite material, such that the NiZn ferrite material thermal shock resistance can be evaluated. The method of the present invention is quick and effective, and the test equipment is simple and feasible.

Description

technical field [0001] The invention belongs to the technical field of material testing, and in particular relates to a method for evaluating the thermal shock resistance performance of a NiZn ferrite material. Background technique [0002] Soft ferrite materials mainly include two series of MnZn and NiZn ferrites, which are widely used in communication, computer network, power supply and consumer electronics, and are important basic functional materials in the electronic information industry. As an important class of soft ferrite materials, NiZn ferrite is favored in the high-frequency (1-300MHz) field due to its advantages of high resistivity, good high-frequency characteristics, and low loss tangent. [0003] At present, during the actual service of NiZn ferrite, due to temperature changes in the working environment or self-heating, etc., thermal stress is generated inside the material. When the thermal stress exceeds the strength of the material itself, cracks will initi...
