The biggest PSPs (27 ± 8 µm) and the highest area fraction (23%) were found in the sample solution treated at 470°C and cooled in the furnace.

It was found that within the test temperature range, the reduction in area values of titanium-bearing steels were almost greater than 40%, which were much larger than those of titanium-free steels. This improvement was due to the formation of (TixNb1-x)(CyN1-y) precipitates and titanium-aluminium oxides with high titanium content that could act as the nucleation sites for dimples to promote the occurrence of ductile fracture.

During their hardening, the coagulation of liquid glass occurs, as a result of which the mixture obtains high strength characteristic. A significant drawback of moulding mixtures based on water glass is low knockout due to increased sintering ability of water glass with moulding sand. To improve knockout, weak additives are introduced into the composition of moulding mixtures. This paper analyses the characteristics of organic weak additives for the composition of moulding mixtures based on water glass. It is shown that the main indicators which affecting to the knockout of mixtures are the amount of evolved gases and the forming carbon formation. With an increase in coefficient of thermal destruction, the knockout of the mixtures based on water glass mixture is reduced by increasing the amount of formed carbon.","PeriodicalId":13939,"journal":{"name":"International Journal of Cast Metals Research","volume":" 2","pages":"162 - 168"},"PeriodicalIF":1.4,"publicationDate":"2021-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41254660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
