| Popis: | The paper studies the structure and mechanical properties of Kh12 and R2AM5F2NYu tool steels and ZChKh25 cast iron produced by gas spray forming. It is shown that rapid solidification during spray forming changes not only the structural type but also the class of materials and substantially improves deformability and mechanical properties. Billets from wear-resistant cast iron formed by spraying can be deformed by hot forging, stamping, and rolling with strain to 30%. |
