“…All-hydrogen batch annealing of cold rolling can eliminate the residual stress, obtain recrystallized grains, and obtain a bright and smooth surface [17,18]. Thus, changing the batch-annealing process will change the microstructure [19,20], mechanical properties [21,22], and surface roughness [23,24] after batch annealing; these, in turn, may affect the microstructure, mechanical properties, and the oxide decarburized layer after austenitizing. A hot-stamping parts production company found that the oxide scale in the hot-stamping process decreased when the initial coldrolled sheet's batch-annealing temperature decreased.…”

In this paper, the effect of batch-annealing temperature on the oxidation of 22MnB5 steel during austenitizing was studied. When the batch-annealing temperature was decreased from 690 to 680 °C, the surface roughness of cold-rolled 22MnB5 steel decreased, which reduced the oxide layer thickness during the subsequent austenitizing process and had little effect on the mechanical properties in the cold-rolled and quenched state. This indicated that oxidation during austenitizing could be reduced by properly reducing the batch-annealing temperature without affecting the mechanical properties.

Two ferritic stainless steel (FSS) specimens, denoted as loading axis along the rolling direction(LR) and the transverse direction(LT) respectively, were produced to elucidate the mechanical anisotropyof409L FSS at grain scale. This approach was realized by the combination of in-situ tensile test and field emission scanning electron microscopy (SEM) with electron backscattering diffraction (EBSD) at room temperature. Microstructure evolution, grain orientation rotation, and crystallographic slip were investigated in the tensile test. During tensile deformation, the tensile axis of LR specimens rotated towards the <101> direction, which is the stable end orientation of body-centered cubic (BCC) metals. However, the rotation of tensile axis towards <101> was restrained in LT specimens due to the operation of less favorable slip systems. {110}<111> was the most favorable slip system in both specimens. The mechanical anisotropy in grain scale is due to different slip behaviors of LR and LT specimens.

Objectives To investigate the impact of simulated gastric acid on the surface properties of lithium disilicate–reinforced glass–ceramics and zirconia-reinforced lithium silicate glass–ceramic after certain polishing and glazing procedures. Materials and methods Four different types of square-shaped specimens (10 × 10 × 2 mm3, n = 13) were manufactured: lithium disilicate–reinforced glass–ceramic milled and polished (LDS-P); milled, polished, and glazed (LDS-PG); milled, glazed, and no polishing (LDS-G); and milled and polished zirconia-reinforced lithium silicate glass–ceramic (ZR-LS). Specimens were immersed in hydrochloride acid (HCl 0.06 M, pH 1.2) to simulate gastric acid irritation and stored in the acid for 96 h in 37 °C. Specimen weight, surface gloss, Vickers surface microhardness and surface roughness (Ra, Rq, with optical profilometer), and surface roughness on nanometer level (Sq, Sal, Sq/Sal, Sdr, Sds with atomic force microscope) were measured before and after the acid immersion. Results ZR-LS specimens lost significantly more weight after acid immersion (p = 0.001), also surface microhardness of ZR-LS was significantly reduced (p = 0.001). LDS-G and LDS-PG showed significantly lower surface roughness (Sa, Sq) values compared to LDS-P before (p ≤ 0.99) and after (p ≤ 0.99) acid immersion and ZR-LS after acid immersion (p ≤ 0.99). Conclusions Gastric acid challenge affects the surface properties of lithium disilicate–reinforced glass–ceramic and zirconia-reinforced lithium silicate glass–ceramic. Glazing layer provides lower surface roughness, and the glazed surface tends to smoothen after the gastric acid challenge. Clinical relevance Surface finish of lithium disilicate–reinforced glass–ceramic and zirconia-reinforced lithium silicate glass–ceramic has a clear impact on material’s surface properties. Gastric acidic challenge changes surface properties but glazing seems to function as a protective barrier. Nevertheless, also glazing tends to smoothen after heavy gastric acid challenge. Glazing can be highly recommended to all glass–ceramic restorations but especially in patients with gastroesophageal reflux disease (GERD) and eating disorders like bulimia nervosa.
