The extrusion of both non-hardening and hardening material is discussed. Taking into account of the strengthening of extruded material is described in detail for a case of hardening material. The presented formulae allow one to determine such most important parameters of the pressing process as total and specific strain forces, maximum pressure on a die wall, an increase in yield load.","PeriodicalId":123591,"journal":{"name":"Technology of metals","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125385401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
