Two casting methods were examined: direct casting from the melting–stirring unit and billets casting. The billets had been precast with thixotropic properties, and were heated again by an induction furnace before the casting. The apparent viscosity of the semisolid magnesium slurry during continuous cooling was found as a function of the casting temperature. Viscosity tests show that the appropriate casting temperatures in the two-phase region were in the range of 595–575 °C for AZ91 alloy and 620–614 °C for AM50 alloy. At casting temperature of 585 °C, AZ91 exhibited maximum density and the highest standard mechanical properties. AM50 alloy demonstrated the relative poor mechanical properties in the two-phase region. The toleration of heat treatment of semisolid AZ91 alloy with a 1.8-fold increase in the elongation-to-fracture was observed. No significant differences of the densities and the standard mechanical properties of the alloys between direct or billet castings were demonstrated.</div>","PeriodicalId":100798,"journal":{"name":"Journal of Light Metals","volume":"2 2","pages":"Pages 81-87"},"PeriodicalIF":0.0,"publicationDate":"2002-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1471-5317(02)00026-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72110593","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}

The limiting dome height test is used to evaluate formability of the TWBs. Three gauge combinations utilizing AA5754 sheets are considered (2 to 1 mm, 1.6 to 1 mm and 2 to 1.6 mm). Different weld orientations have been considered: transverse and longitudinal. In general, TWBs show two different types of fracture: weld failure and failure of the thinner aluminum sheet. Interaction of several factors determines the type of failure occurring in a TWB specimen. These factors are weld orientation, morphology and distribution of weld defects as well as the degree of constraint imposed by the thicker sheet on the thin sheet. The last factor usually depends on the difference in thickness of the sheets and is represented here in terms of gauge ratio.</div>","PeriodicalId":100798,"journal":{"name":"Journal of Light Metals","volume":"2 2","pages":"Pages 95-110"},"PeriodicalIF":0.0,"publicationDate":"2002-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1471-5317(02)00028-7","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72110595","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}
