“…The springback behaviour caused by the elastic stresses that occur during deformation in the materials is also observed in the forming processes made by bending. The dimensional and geometric accuracy of the formed materials is affected by the springback behaviour [36]. For this reason, it is important for mass production that springback behaviour has been under control and stay within the desired tolerances.…”

In this study, the effects of local heat treatment using a low-power laser on the bending formability of DP800 sheet material were experimentally investigated. In the first step of the study, only the punch contact bending region of sheet metal was locally heated with a constant feed rate (1 mm s −1 ) and at different laser powers (50, 75, and 100% Watt). In the next step, the sheet material was transferred to the bending die for bending without any cooling process, and into the last stage, the sheet material was formed in different angled V-bending dies (30°, 60°, and 90°). It was observed that in heating up to 75-W power, the hardness decreased to 237 HV due to the dissolution of the martensite in the microstructure of DP material, and the springback value decreased by 39.285% due to the decrease in hardness.

Part of the tunnel spoil can not be used for concrete due to alkali-aggregate reaction (AAR). Water is an indispensable condition for AAR, so separating the alkali-aggregate from water is of great benefit to controlling the AAR. This paper investigates the modification of concrete and aggregate by hydrophobic impregnation and organic coating and then evaluates their waterproof and mechanical properties by dynamic contact angle (DCA), ultrasonic wave velocity, scanning electron microscope (SEM), nuclear magnetic resonance (NMR), and so on. For waterproofness, hydrophobic impregnation and organic coating can both improve the waterproofness of concrete and aggregate. The organic coating is suitable for aggregate because it wrap aggregate well. And aggregate coated by PVA can improve the interfacial transition zone (ITZ). For mechanical properties, both materials will weaken the strength of the interface. Furthermore, concrete made by aggregate with organic coating shows plastic deformation and has a good correlation with the film thickness, a plastic estimation model based on film thickness is proposed. This paper evaluates the waterproof of concrete and aggregate and finds plastic concrete with good aggregate waterproofness which provides a new idea for the application of alkali-aggregate in seepage control facilities of water conservancy projects.
