چکیده
|
This article examines the weibull statistical analysis that was used for investigating the effect of meltfiltration on tensile properties and defects formed inside the casting. forming and entrapping of double oxide filmshave been explained by using the context of critical velocity of melt in the runner. sutcast software results were usedto examine the amounts of the velocity of melt as such. sem/edx analysis is used to observe the presence of doubleoxide films in the fracture surfaces of the tensile specimens. the article goes on to propose that castings made withfoam filters with smaller pores show higher mechanical properties and reliability due to higher weibull modulus andfewer defects.
