“…There are so many studies that have derived a relationship between the microstructural phases, changes in microstructure, changes in the stresses, and mechanical properties with the magnetic behaviour of the materials. [34,[45][46][47][48][49] Saturation magnetization is an inherent property that can be influenced by atomic or molecular structure, magnetic moments, crystal and microstructure, temperature, magnetic anisotropy, or magnetic interactions. While the microstructure is totally dependent on the processing undergone by the material, the consequent changes resulting in the size and alignment of magnetic domains affect the M S .…”

The microstructural phases in steel influence the magnetic moments due to different alignments and arrangements of the atoms in the crystal lattice. This study is based on the relationship of the microstructural phases with saturation magnetization (MS), a characteristic magnetic property of a phase in a material. Understanding the changes in microstructural phases during steel processing is paramount for different industries to fulfill the desired mechanical properties of the grade. The current research investigates the microstructural phases and magnetic properties of industrial‐grade high‐carbon steel under compressive and controlled‐thermal deformation to obtain a dual‐phase steel microstructure, i.e., retained austenite and martensite. High‐carbon steel samples are subjected to compression and heat treatments, resulting in different variations of dual‐phase structure. The sample microstructure is characterised using optical microscopy, and scanning electron microscopic analyses, and their phases are quantified using X‐ray diffraction, complemented by electron back‐scatter diffraction techniques. An empirical relationship between the microstructural phases of steel and the magnetic characteristics is derived based on the magnetic measurements determined using a SQUID magnetometer. The correlation statistically holds good for high‐carbon steels. This relationship between the volume of transformation of retained austenite (VRA) to martensite (VM) and the magnetic properties is successful in investigating the possibility of a non‐destructive method for evaluating dual‐phase low‐alloyed high‐carbon steels.

“…It is a new stress nondestructive testing technology by using the magnetic stress coupling effect of ferromagnetic materials [7][8][9]. The magnetic properties of ferromagnetic materials alter with the change of stress [10][11][12][13]. It shows a good application prospect in stress detection by obtaining the change of magnetic characteristic parameters of test pieces [14][15][16].…”

Complexity of service environment and particularity of the transportation medium make it difficult to develop a nondestructive stress testing on oil and gas pipelines in real time and online. In this case, a stress detection method of oil and gas pipelines is proposed in this work based on the magnetic mechanical properties of pipeline steel materials and the magnetic induction intensity stress coupling relationship. Six commonly used pipeline steels (X52, X56, X60, X65, X70, and X80) are selected as the research objects to test the hysteresis curves. The key parameters of local magnetization of oil and gas pipelines are determined based on their magnetic properties. A finite element simulation model is established for oil and gas pipelines with magnetic field and stress field coupling. The magnetic field distribution and magnetic induction intensity along the length of the pipeline and the height of cross section are studied after local magnetization of the simulation model of oil and gas pipelines unpressurized. The mechanism of magnetic induction intensity and stress variation of the simulation model of oil and gas pipelines with different internal pressures are discussed. The coupling relationship of axial stress, circumferential stress, and magnetic induction intensity are separately established. The systems for stress-strain test and magnetic induction intensity test are integrated to test the X80 pipeline steel. Analysis results on test data and finite element simulation data verify the validity of magnetic coupling simulation of oil and gas pipelines and the reliability of stress detection, which provides a theoretical basis for the key technologies of nondestructive online stress detection of oil and gas pipelines.
