Friction Stir Processing of Aluminum Alloy 5083 Plate for Cold Bending

Modern Manufacturing Engineering

“…As can be seen, it differs from those used by De Chiffre, in patent US 7,617,750 (2009), patent application US 2014/0017113 (2014), and papers [63,66] in one, but essential, aspect, namely face cutting instead of disk cutting (as shown in Fig. In the setup used by Den et al [71], there is no cutting speed variation as this speed is defined by the rotational speed of the workpiece, n (rpm) and workpiece diameter which does not change. In the latter case, the cutting speed decreases as tool progresses if the workpiece rotates at the same rotational speed as the diameter of the workpiece decreases.…”

“…The most noticeable paper in this respect is that by Den et al [71]. The experimental setup used in their study is shown in Fig.…”

“…Analyzing modeling of strains in LSEM Cai et al [71] shows that the formula for strains in LSEM proposed by De Chiffre (Eq. 1.15 is the same as that for orthogonal cutting Eq.…”

Semi-Friction Stir Processing the Method for Improvement of the Product Surface Layer

“…During the operation of the switchgear it is necessary to maintain a constant working pressure of SF 6 . If the pressure were to reduce by 0.05 MPa, an emergency disconnection of the switchgear occurs.…”

“…The main applications of the process include: elimination of casting defects in the form of porosities or shrinkages and refinement of surface microstructures, thereby improving strength and ductility and increasing resistance to corrosion and fatigue [1,4,5]. The application of this method is used in the processes of bending and stamping [1,6]. FSP can also produce fine-grained microstructures through the thickness to impart superplasticity as well as produce in-situ surface composite by stirring the base material with the strengthening particles, e.g.…”
