“…Treated by a predeformation, the grains are elongated along the rolling direction, and as the deformation amount is increased, the grains are refined. The same phenomenon is observed in the extrude Al–Cu–Mg–Ag alloy (Xu et al , 2018).…”

Purpose The effects of the thermo-mechanical treatment on the properties and microstructure of the Al–Cu–Mg–Ag alloy were investigated. Design/methodology/approach A short-duration preprecipitation process is designed prior to predeformation aging. The novel predeformation aging (solution treatment + holding at 185 °C for 15 min+ rolling deformation + aging at 185 °C, also named T8) was performed on a heat-resistant Al–Cu–Mg–Ag alloy. Findings The purpose of this study indicate that a short-duration heat treatment before predeformation is beneficial to the precipitation of O during the aging process. The precursors of O during this process might pin the dislocation and cause the grains to orient along some specific direction, which might be advantageous to the precipitation of O while disadvantageous to that of θ′. This novel thermal-mechanical process could result in an increase in the quantity and decrease in the size of the precipitation of O, which leads to a remarkable strength effect. The potential increases while the current density decreases with an increase in the deformation amount, which implies a smaller intergranular corrosion rate. The fine deformed structure leads to an opposite behavior in the exfoliation corrosion test compared with that for intergranular corrosion. Originality/value The intergranular corrosion resistance of the Al–Cu–Mg–Ag alloy is enhanced, whereas the exfoliation corrosion resistance is reduced by novel predeformation aging.

“…Additionally, Y 2 O 3 was also used to accelerate sintering of the corundum matrix through the formation of the YAlO 3 (YAP) phase, which was beneficial to improve the properties of the corundum dry vibratable refractory. 9 The study conducted by Feng et al 10 examined the impact of incorporating borax into magnesia-based dry vibratable refractory and its resulting properties. The results revealed that the addition of borax significantly improved the slag resistance of the dry vibratable refractory.…”

Fe–Si3N4 was introduced to improve the service performance of corundum‐based dry vibratable refractories in the casting industry, specifically enhancing their thermal shock resistance and resistance to slag corrosion. The study analyzed the effects of Fe–Si3N4 powder content on the refractories’ mechanical properties, phase compositions, slag corrosion resistance, and microstructures. The addition of Fe–Si3N4 facilitated the production of magnesium aluminate spinel in the refractory matrix, while also decreasing the wettability between the molten slag and refractory. Increasing the Fe–Si3N4 content resulted in accelerating the replacing Mg2+ (0.072 nm) with Al3+ (0.053 nm) in the spinel. Simultaneously, Fe3+ (0.055 nm) was effectively dissolved into the alumina crystals. The bulk density, compressive strength, and slag corrosion resistance of the refractories were improved. However, the thermal shock resistance initially increased but then decreased. In industrial tests, a corundum‐based dry vibratable refractory with a 1 wt.% Fe–Si3N4 content effectively prolonged the lifespan of an induction melting furnace when used as a lining refractory. Importantly, the refractory did not spall or generate cracks in the matrix after induction melt furnace industrial test.
