Ultrasonic technique for express estimating the mechanical properties of the rolled copper plates

Measurement possibilities of moving rolled copper sheets phisical-mechenical characteristics are proved. Measurement method of mean grain size is presented. For 99,9% purity copper Hall-Petch's relation is obtained. Using this equation one can determine yield point of materials knowing mean gra...

Description
Summary:Measurement possibilities of moving rolled copper sheets phisical-mechenical characteristics are proved. Measurement method of mean grain size is presented. For 99,9% purity copper Hall-Petch's relation is obtained. Using this equation one can determine yield point of materials knowing mean grain size.
