The relationship of stress vs. strain of W-40 wt.% Cu at different temperatures and strain rates is obtained by the true stress-strain data obtained from tests using a Gleeble1500 thermo-simulator. The friction factors without and with lubricant of oil and graphite are determined by ring upset exper
