film of nickel-containing paste was placed to reduce the friction. Before compression, the specimens were resistance-heated at a rate of 5 K/s and then kept at the preset temperature for 120 s. The test... as an overall heat-transfer coefficient. Based on the above theories concerning friction correction and temperature rise correction, the flow stress during the whole compression process can be modified......
