The production of semi-finished products made of refractory metals is considered. The advantage of parts production using combination of two types of straining with change in the straining direction: direct extrusion and equal-channel pressing is shown. The experimental investigation data of pure and simple shear for the semi-finished products processing made of tungsten and molybdenum are presented. Requirements for the tool providing diagonal flow and angular straining are formulated based on the analysis of the stress-strain state of the processes of axial symmetric extrusion and simple shear of plastically inhomogeneous body. Effectiveness evaluation of the combination of various types of fixtures and the rational sequence for using of diagonal flow and angular pressing is given. Experimental devices for practical application of the proposed technology are developed.

Tribological Parameters

The present work investigates the tribological properties of AA6061/1.5 wt.% SiC/1.5 wt.% B4C hybrid nanocomposites prepared using stir casting technique. The effect of sliding distance, sliding speed and load were investigated on wear rate (WR) and coefficient of friction (COF). Response surface methodology was used to predict and model the responses. Analysis of variance showed that sliding speed and load were the significant factor affecting WR and COF respectively. Desirability analysis was performed for both single and multi-objective optimization. The minimum WR and COF were found to be 0.0015 mm3/m and 0.2430 at sliding distance of 1939.39 m, sliding speed of 1.99 m/s and load of 10 N.
