“…In order to increase the weather resistance of spheroidal graphite cast iron (S. G. cast iron), increased silicon content is easier to operate. 1) There are a few reports on erosion wear of the cast iron suggesting that by increasing the area fraction of the pearlite phase through heat treatment an improvement on erosion resistance may be achieved, [2][3][4] however there were very few studies that examined the effect of silicon content on erosion resistance of full pearlitic S. G. cast irons regarding the investigation of SiO 2 particle erosion. 4,5) A quantitative investigation is required to determine the relationship between erosion resistance, factors of the solid solution strengthening, and cementite lamellae change.…”

The effect of morphology and Si content on SiO 2 particle erosion wear of full pearlitic spheroidal graphite cast iron was studied. Experimental data shows the specimens posses more area fraction of cementite for an identical silicon content, that contribute to improve erosion resistance. However, the specimens posses larger interlamellar spacing (λ) at increased Si content, even if the matrix hardness is higher that still debase the erosion resistance. The 2.1Si-air(930 • C) specimens not only possess finer λ value and larger cementite fraction but also with better ductility, which could improve erosion resistance.

“…1,2) Austempered ductile iron (ADI) encounters particle erosion when it is used to perform functions in equipment including farming tools, blast machines, and automatic sand molding equipment. [1][2][3][4] Though many previous research efforts have investigated the effect of silicon content and austempering duration on the micro-structural changes of ADI, and confirmed that it can be correlated to the mechanical properties of ADI, [2][3][4][5] few studies have focused on examining the effect of Si content (up to about 4.0 mass%) on erosion wear resistance.…”

The Microstructural Effects on Tensile Properties and Erosion Wear Resistance in Upper Bainitic ADI Related to Variation in Silicon Content

2002

The Effects of austempering duration and silicon content on the particle erosion wear resistance of high strength upper bainitic ADI were characterized. The results showed that the amount of retained austenite dominantly affects tensile strength and variation of wear resistance. For a sample with higher silicon content, the austempering duration should be prolonged to ensure complete bainitic transformation. In addition, a tiny increase in carbide formation can certainly play an important role in debasing tensile strength and erosion wear resistance. This results in an alternation in erosion behavior. However, hardness cannot be correlated to wear resistance. Erosion-induced phase transformation of retained austenite phase will eventually produce ε-carbide, which thus promotes the erosion wear rate.

“…The effect of silicon content on the mechanical properties and erosion resistance has been clarified in many previous reports on ADI. [1][2][3][4][5][6] Therefore, the application of ADI must have controlled the silicon content and retained austenite content to improve the fracture toughness. 2) In this investigation, the erosion mechanism of Stage I and Stage II ADI with the same chemical composition by varying systematically austempering duration is required to recognize.…”

“…[1][2][3][4] Reports on the erosion wear of cast irons indicated that erosion resistance can be improved through heat treatment. [1][2][3][4][5][6] However, relatively few studies relating to the effect of austempering duration on erosion resistance of ADI regarding the investigation of Al 2 O 3 particle erosion can be found readily. 1,2,6) Generally, increasing the silicon content in ADI at the given temperature and austempering duration will increase the amount of retained austenite and suppress the carbide formation.…”

Effect of Austempering Duration on Erosion Wear Resistance of ADI by Al2O3 Particle

2003

Effect of the duration of austempering on particle erosion wear resistance of ADI was studied. In short duration (Stage I) region, a fair amount of martensite phase can be recognized, and hence deterioration of erosion wear resistance. In initial Stage II, the austempering region (0.5 hr duration) is free of carbide. If prolonged the austempering duration, the retained austenite amount tend to decrease and hence carbide formation. Even if slightly increase of carbide amount that still can play an important role on debasing wear resistance, resulted from the alternation of erosion behavior. Erosion-induced phase transformation of retained austenite also can be determined that is generality transformed to "-carbide.
