Effect of TiO2 nanoparticles on the bond strength of CP Ti sheet by cold Rolling method
In this work, the strength of cold roll bond of the commercially pure titanium (CP Ti) sheet and the effect of TiO2 nanoparticles on bond strength was investigated. Through the accumulative roll bonding process, which is considered among the important severe plastic deformation processes, the creation of suitable bonds plays a significance role in the ultimate strength of the bond. Thus, resear...

متن کاملPrecipitation evolution in Al–Zr and Al–Zr–Ti alloys during isothermal aging at 375–425 C
Formation of Al3Zr or Al3(Zr1 x Tix) precipitates with a metastable L12 structure was investigated in conventionally solidified A1–0.1 Zr, Al–0.2 Zr, Al–0.1 Zr–0.1 Ti, and Al–0.2 Zr–0.2 Ti (at.%) alloys aged isothermally at 375, 400, or 425 C. Pronounced hardening results from nanometer-scale, spheroidal Al3Zr or Al3(Zr1 xTix) (L12) precipitates within solute-enriched dendrites. Interdendritic ...
متن کاملAn Upper Bound Analysis of Sandwich Sheet Rolling Process
In this research, flat rolling process of bonded sandwich sheets is investigated by the method of upper bound. A kinematically admissible velocity field is developed for a single layer sheet and is extended into the rolling of the symmetrical sandwich sheets. The internal, shear and frictional power terms are derived and they are used in the upper bound model. Through the analysis, the rolling ...
متن کاملAsymptotic analysis of asymmetric thin sheet rolling
An analytical model for asymmetric rolling is presented, which includes asymmetry in roll friction, roll size and roll speed, for a rigid, perfectly plastic thin sheet deformed with Coulomb friction. This model is solved asymptotically, based on the systematic assumptions that both the roll gap aspect ratio and the friction coefficient are small. While the leading order solution is shown to be ...
