The purpose of this work is to evaluate the performance several wear models, either with different mathematical formulation or definition unknown coefficients, on prediction work-roll amplitude in Hot Strip Mills (HSM). To achieve goal, a classical model calibration approach based inverse optimization has been developed calibrate these models. A large industrial hot rolling database composed by...

In this research, Al-Ni particle composite strips are formed by accumulative roll bonding (ARB) process using Al strips and Ni powder. The rule of ARB cycles and volume percentage (Vol%) of Ni powder on the microstructure, wear resistance and mechanical properties of the formed composites are investigated. According to the tensile test results, the yield stress and tensile strengths of the Al -...

Introduction One of the common prostheses for primary total knee arthroplasty (TKA) is a cruciate-retaining (CR) design. The tibial polyethylene inserts commonly used in TKA are made of ultra-high molecular weight polyethylene (UHMWPE). The CR TKA design retains the posterior cruciate ligament (PCL), which is believed to provide increased stability, promote femoral roll back, improve propriocep...

Abstract This study first tried to fabricate AA1060/Al 2 O 3 composites via the stir casting and accumulative roll bonding process. Then, effect of nano Al Vol% on mechanical, wear, microstructural properties these kinds have been investigated. An excellent particle distribution through aluminum matrix has achieved after fourth cycle. mechanical properties, wear resistance, The results showed t...

An experimental approach is presented for the measurement of wear that is common in the threading of cold-forged steel. In this work, the first objective is to measure wear on various types of roll taps manufactured to tapping holes in microalloyed HR45 steel. Different geometries and levels of wear are tested and measured. Taking their geometry as the critical factor, the types of forming tap ...
