Determination of oxygen amount in the deformed copper by methods of stereometric metallography is considered. The volume amount of cuprous oxide in eutectic Cu-Cu₂O is determined in the program of images processing IMAGE-SP. It is shown that known value of density of cuprous oxide (6 g/cm³) doesn’t ensure possibility of the correct calculation of the structural components content. Value of 1,53 g/cm³ is determined for cuprous oxide density.

Schemes of rolling of striped blanks on swage at various values of their front tension are considered.

The matters of influence of cast structure on level of hardening of tool steel of type 4X2BMC with various proportions of elements in their structure are considered. It is shown that presence of cast structure can provide hardness increase up to 5-15% of the experience value that is especially necessary at tempering temperatures of 600 ° C and over.

The conducted researches of continuous stability of microstructures of the fast-quenched tapes from alloys of aluminum and chrome showed that the natural aging accompanied by discharge of stable phases is observed in copper-bearing alloys. There are no changes in microstructure in the chrome-bearing fast-chilled tapes that confirms their high temporary stability.

Influence of preliminary high-temperature processing on structure formation of the diffusionalloyed waste of high-phosphorus cast iron shot is investigated.
