These result in lowering of the average mechanical properties and the yield of the casting. In the past, the use of external chills to reduce the above defects has had limited effects. This is because the influence of external chills becomes marginal beyond a certain distance. One of the potential methods of overcoming such problems is to employ heat sinks in the form of internal chills. Despite reported work by Russian and Japanese investigators on the use of internal chills, in the form of powder or strip, in iron and steel castings, no detailed information on the use of such chills in aluminium or other non-ferrous alloys is available in the literature.This paper presents deta...","PeriodicalId":9691,"journal":{"name":"Cast Metals","volume":"9 1","pages":"65-83"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73791765","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}

In attempting to identify the role of the microstructure in relation to toughness, a number of microstructural parameters, including dendrite spacing (λd), mean free path (MFP) across the dendrites (i.e., edge-to-edge dendrites spacing), in addition to Si particle size, morphology and spacing, are considered. It has been found that the microstructural change has affected the toughness of the alloy under investigation in two ways, namely an increase in the initiation energy required for fracture, and an increase in the propagation energy of fracture. The presence of fine Si particles of low aspect ratio and with a beneficial degree of sphericity has affected the initiation energy as a result of an improvement in the resistance to void initiation. In the case of propagation energy of fracture, the void size and its effect of local strain concentrati...","PeriodicalId":9691,"journal":{"name":"Cast Metals","volume":"118 1","pages":"103-111"},"PeriodicalIF":0.0,"publicationDate":"1994-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87941929","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}
