Mechanical Properties of Forgings Depending on the Changes in Shape and Chemical Composition of Inclusions

Enlargement of quality requirements in metallurgical semi products used in cannon barrels production (forgings) has resulted in substantially increased number of defective products. The main issues are poor quality of plastic properties and yield point of processed materials. Careful analysis of forgings technology and adaptation of its constituent phases has not resulted in the quality enhancement of the forgings. Consequently, the issue is searched in metallurgical phase of production technology. 1-3 .
