Study of wear of the building-up zone of martensite-austenitic and secondary hardening steels of the Cr-Mn-Ti system

Study of wear of the building-up zone of martensite-austenitic and secondary hardening steels of the Cr-Mn-Ti system

The work deals with wear of the building-up zone of martensite-austenitic and secondary hardening steels of the Cr-Mn-Ti system (partially alloyed with Mo, B, and V). Additional alloying of the studied steels with titanium in the amount of 2…5% supported avoiding cleavages along the building-up zone...

Досліджується зношування зони наплавлення мартенситно-аустенітних і вторинно-твердіючих сталей системи Cr-Mn-Ti (частково легованих Mo, B, V). Додаткове легування досліджуваних сталей титаном у кількості 2…5% сприяло запобіганню сколам по зоні сплавлення. Встановлено, що поблизу лінії сплаву знаходиться зона основного металу шириною 7…15 мкм. Вплив температури на в’язкість руйнування зони наплавлення оцінювався за критерієм Малкіна та Тетельмана. Мікротвердість поверхневих наплавлених шарів та діапазон її розкиду близькі результатам лабораторних випробувань при Тcₜ ∼ 823 К. Це свідчить про формування структури металу контактних об’ємів сукупною дією нагріву, пластичної деформації, дифузії. Експериментально підтверджено, що зміна мікротвердості в приповерхневих шарах на стадії зносу зумовлено паралельно процесами взаємної дифузії матеріалів пар тертя, виборчого окислення і термодифузійного перерозподілу зміцнюючої фази під дією температур і деформацій. Коефіцієнт дифузії в деформованому приповерхневому шарі товщиною до кількох десятків мікрометрів є однією з величин, що зумовлюють кінетику зростання зародкових тріщин та розвитку тріщин руйнування. Отримані результати дають можливість використовувати мартенситно-аустенітні та вторинно-твердіючі сталі системи Cr-Mn-Ti з наплавленою поверхнею для інструменту гарячого деформування. 2023 Article Study of wear of the building-up zone of martensite-austenitic and secondary hardening steels of the Cr-Mn-Ti system / D.B.
