Brief overview of effects of temperature rising rate on mechanical properties of metals
Researches into effects of temperature rising rate on mechanical properties of metals under rapid heating are reviewed,including those carried out by American researchers using methods of macroscopic tensile-heating experiments in 1950 or so and those by domestic researchers employing combined methods of macroscopic property measurements and microscopic constitution observations in recent years.It is mentioned that,as far as effects of temperature rising rate on mechanical properties of metals is concerned,more accurate and systematical macroscopic-microscopic experiments and theoretical modeling and numerical simulation of multi-scale thermo-mechanical-material coupling should be performed,clearer laws should be understood,and available mathematical formula in engineering should be developed in the future.
