study of al cast iron interface and graphite behavior

A Look at Today's Cast Iron

Gray cast iron characteristically has flake graphite and ductile iron nodular graphite, as seen in the microphotographs on the next page. Cast irons are classified as free machining because the graphite acts as a chipbreaker similar to the way sulfides, phosphides and lead act in resulfurized, rephosphorized and leaded steels.

Effects of Graphite Content and Temperature on Microstructure and Mechanical Properties of Iron

In order to obtain iron-based powder metallurgy specimens and study the effects of graphite content and temperature on its microstructure and mechanical properties, the iron powder and the graphite powder were prepared. The chemical composition (wt.%) of the

graphite forms on the surface of molten iron upon its cooling because of the oversaturation of iron with carbon, which typically occurs in cast iron making or blast furnace processes (usually from hypereutectic compositions).53,54 As formed, kish and iron.

Interface pressure distributions and thermal contact

The main area of interest was the conduction between the grey cast iron disc and the spheroidal graphite cast iron wheel carrier. The bolt clamp forces and interface pressure distributions were investigated theoretically and experimentally.

Determination of interface heat transfer coefficient

In this study, the interface heat transfer coefficient h between the cylindrical aluminum (99.99%) casting and the mold made of block graphite of the GMZ (low ash graphite) grade was determined. The mold was produced by milling using a CNC milling machine.

[PDF] Strain Rate and Stress

An investigation of the mechanical strain rate, inelastic behavior, and microstructural evolution under deformation for an as-cast pearlitic gray cast iron (GCI) is presented. A complex network of graphite, pearlite, steadite, and particle inclusions was stereologically quantified using standard techniques to identify the potential constituents that define the structure–property

3.1 As-cast material Figure 1 shows optical micrographs of the as-cast ductile iron alloy. The microstructure was composed of 14% graphite, 52% ferrite and 34% perlite. The measured nodule counting was 197 nodules per mm 2 with 85% nodularity. As shown in Figure 1a the graphite nodules in the as-cast material were not uniform in size and distribution.

Effects of alloying elements on the microstructure and fatigue properties of cast iron

this question lies in the fact that there is little data for the behavior of cast iron alloys at high temperature. For this study two different types of cast iron, 50HS and HSM will be examined. Of particular concern for the high Si+C cast irons (and Mo in the case of

In the present study, two kinds of vermicular graphite cast samples (RuT400 and RuT450, Chinese designation) were cut from the cylinder heads. The chemical compositions are shown in Table 1.As shown in Fig. 1, thermal fatigue specimens with a V-shaped preformed notch were machined by wire electrical discharge machining and followed by polishing.
