Abstract

Heat Treatment and Alloying of Spherulitic Graphite Cast Iron for Intensification of Properties

Highlights

  • Ductile Iron is likewise ordinarily known as "Nodular Iron" or Spheriodial graphite (S.G) iron was licensed in 1948

  • Mechanical Properties The mechanical properties measured by using Universal testing machine and greyensions of specimen was carried out according to ASTM (A 370-2002), are castn in Table 3 and Table 4,lists the mechanical properties of tensile strength, yield stress, elongation and hardness of ductile ironsN1, N2 respectively

  • Extension for Austempered Ductile Iron (ADI) is The following observations were acquired tentatively expanding from 0.5 hr. to 1.0 hr. with slight amid Austempering heat treatment diminished from 1.0 hr. to 2.0 hr. as appeared in figure 4.c and 5.c, which demonstrates I)
