Abstract

A friction model with the help of ANSYS software is made for cold strip rolling under hydrodynamic lubrication. The finite element model is developed from a flow problem of non-Newtonian incompressible fluid. The result of solution is nodal velocities over the arc of contact and the friction (shear stress) model is determined using the formula developed by Saxena et.al. The friction model as a result of applying ANSYS software shows the same trend as the existing developed model

Abstract

Proses pengerasan presipitasi adalah salah satu metode untuk meningkatkan kekuatan material. Dalam penelitian ini ditunjukkan bahwa prinsip tersebut dapat diterapkan pada paduan Aluminium AA 2024 yaitu dengan menerapkan proses TMT yang merupakan gabungan antara perlakuan panas (heat treatment) dan proses deformasi (mechanical treatment). Hasil eksperimen menunjukkan bahwa dengan proses TMT, sifat mekanik Aluminium AA 2024 dapat ditingkatkan. Secara kualitatif, material hasil TMT masih tahan terhadap korosi tegangan dalam salt spray chamber (kadar NaCl 5%) dengan beban 174,55 MPa dan lama pengujian 30 hari
