“…When a ferromagnetic material is subjected to stress, the internal microstructure changes, the magnetic domain structure deflects, and the magnetic characteristic parameters vary significantly, which is called the force-magnetic coupling effect [17,18]. Among them, the magnetic domain is a small area with spontaneous magnetization inside the ferromagnetic material, and the magnetic moment direction of each magnetic domain is different.…”

Buried pipelines are prone to deformation under surface displacement, pressure occupation, and/or other actions, resulting in stress concentration. Conducting regular stress detection is an important approach to reducing pipeline accidents. This study performed experiments on measuring the coercivity stress of X80 steel, the most commonly used material for high-pressure large-diameter gas transmission pipelines. The coercivity of the specimen under different stress combinations was measured using the DC-driven coercive force measurement system, and the variation of coercive force with biaxial stress was also analyzed. The modified coercive force-stress expression of the generalized Hooke’s law was proposed; the model for the coercive force-stress relationship of X80 steel under the biaxial stress state was established based on this expression. The study indicates that the coercive force method is reliable for accurately measuring the stress of pipeline steel and evaluating the safety margin of in-service pipelines.

“…In recent years, porous FSMAs and FSMA composites have attracted great interest due to their potential application in biomedical devices, shock-absorbing devices, and lightweight actuators/sensors [12][13][14][15]. Chmielus et al [16] demonstrate that the MFIS of porous Ni-Mn-Ga alloys can reach 2.0-8.7% by introducing pores smaller than grain size.…”

“…Gebbia et al [1] discussed the hysteresis and MFIS of Ni 2 MnGa at various temperatures by combining the Ginzburg-Landau model and micromagnetism theory. Multi-phase models using the Eshebly theory and Mori-Tanaka method were also employed to investigate the mechanical behaviors and magneto-mechanical coupling between porous FSMAs and FSMA composites under different conditions [12,20]. The multi-phase-field model, as an effective physical-based computational approach, can simultaneously illustrate the evolution of ferromagnetic domain structure and martensite microstructure.…”

The magnetic domain structures and martensite microstructures of porous Ni2MnGa Heusler alloys with various circle-shaped and ellipse-shaped pores were systematically studied by the phase field method. The magnetization curves and magnetic field-induced strains (MFIS) at the external field were determined. A mesoscopic mechanism was proposed for simulation to reveal the influence of the pores on the microstructures and the MFIS of porous magnetic shape memory alloy. The stress concentration effect and the recovery strain of the porous alloy are studied. The results indicate the MFIS value increases when ellipse-shaped pores elongate along the twin boundary. The effects of porosity and pore size on MFIS for porous Ni-Mn-Ga alloys with randomly distributed pores were also explored. The present study is of guiding significance for understanding the role played by pores on the MFIS and may provide a possible way to adjust the functional properties of ferromagnetic shape memory alloys.
