Specifically, under cold pressing of powders with average thinless of metallic systems into rigid matrix array with pressure up to 1000 MPa, and strain rate 0,01 - 0,001 m/sec limiting bound of RBD is an amount approximately equals to 0,4-0,45. It is verified on a raw of metals and alloys' powders. It was shown that in such terms toughness of molding guarantee by mecanical component of tie-up. During the hot pressing cohesion component of tie-up is dominated. The correlation between mode indicator of flat surface and RBD of powder contained these particles, and toughness of derivable moldings were shown. Suggested mono-parametric model allowing to predict the appearance of spill cracks. Product Description popup.authors popup.nrat_date 2020-04-02 Close
