TL;DR: In this article, a series of ideal materials with average grain sizes range from 0.7μm to 30.0μm containing high fraction of high angle grain boundaries (HAGBs), equiaxed grains and low density of dislocations were produced by friction stir processing (FSP).

TL;DR: In this paper, the microstructural evolution on the advancing side, the center, and the retreating side of the stir zone of a lean duplex stainless steel was studied by a combination of electron microscopy and electron backscattered diffraction.

TL;DR: In this article, the effect of interfacial compound on the microstructure and mechanical properties of Ti-steel clad plate was studied by electron probe microanalysis, scanning electron microscopy, X-ray diffraction and shear test.

TL;DR: In this paper, the effect of different compounds at the interface at different heating temperatures on the mechanical properties and microstructure of titanium-steel clad plates were analyzed by electron probe micro-analyzer (EPMA), transmission electron microscopy (TEM), X-ray diffractometer (XRD) and shear test.

TL;DR: In this article, the microstructural evolution and mechanical properties of friction stir welded X80 pipeline steel plates were studied under air, water, liquid CO2 + water, and liquid CO 2 cooling conditions, producing defect-free welds.
