Micromechanical Properties and Deformation Behavior of the Co70Fe3Mn3.5Mo1.5Si11B11 Amorphous Alloy

This work reports an experimental study of the micromechanical properties of the Co70Fe3Mn3.5Mo1.5Si11B11 (at. %) amorphous alloy. All experiments were performed at room temperature on the unannealed sample in order to avoid the influence of thermally induced structural relaxatio...

A Study on the Ball Burnishing Main Regime Parameters’ Impact on Manufacturing Lubricating Groove Widths Formed on the Friction Surfaces of Multilayer Connecting Rod Liners

The present research investigates the optimization of ball burnishing (BB) process parameters to create regular lubricating grooves on multilayer connecting rod liners to prevent engine seizure. The study utilized a Taguchi L9 fractional orthogonal array to evaluate the impact of...

A hybrid combination of analytic hierarchy process and best-worst method: simulation and application

Purpose Among various multi-criteria decision-making (MCDM) methods, the best-worst method (BWM) is acknowledged as an improvement of the analytic hierarchy process (AHP). However, data collected from AHP surveys could not be used in BWM studies and vice versa because the two req...
