Frictional effects on flow stress determination at high temperatures and strain rates
Journal of Mechanical Working Technology(1984)
摘要
It has been reported recently that the average die pressure as measured during the initial compression of non-lubricated cylinders was less than 5% greater than that for lubricated samples, when the final diameter-to-height ratio is less than 2. These tests were carried out at room temperature and low strain-rates.
