Анализ условий работы литых штамповых материалов, работающих при 950–1000 °С, и требования к ним при штамповке в изотермических условиях

Abstract

Статья посвящена литым деталям штампов, которые эксплуатируются в сложных термомеханических условиях при высоких температурах. Основными причинами их выхода из строя является износ гравюры штампа, смятие элементов гравюры и разгарные трещины. Изучение механизма образования данных дефектов в теле литого штампа позволит создать сплавы с высокой термостойкостью и увеличить ресурс штампов при изотермическом деформировании. The article is devoted to stamp cast parts which are operating in complex thermo-mechanical conditions at high temperatures. Main causes of their failure are stamp gravure wear, gravure elements collapse and thermal fatigue cracks. Research of the formation mechanism of these defects in a solid cast stamp will enable to manufacture high heat resistance alloys and to extend the stamp life during isothermal deformation.
