<p>In addition to measurements of physical and mechanical properties, quality inspections also include metallographic analyses. When gray casting iron material, different manufacturing processes cause microstructures in the whose images perform large differences. The properties can be divided into six types (from Type A F). proportion will influence strength, wear resistance, lifetime spe...

Gray cast iron (GCI) with a pearlitic matrix and type-A graphite remains the most widely used material in manufacturing of brake discs. To reduce environmental impact disc wear during braking, alternative materials and/or compositions to standard ones are being studied. In this study, effect variation niobium content (0–0.7 wt%) on microstructure behavior samples machined from discs made hypoeu...

The paper proposes the use of maps expected abrasive wear friction surface a soil-cutting part, which characterize intensity at various points during its movement in soil environment. importance this work is caused by changes modern technologies for cultivation agricultural crops, requiring geometric shapes parts with need to predict their service life. A study physical and mechanical propertie...

Throughout many parts of the world, cast iron pipe has been and continues to be used for utility piping (water sewage) gaseous media piping. Gray is known have a limited life in service but often left place beyond its reasonable life. Therefore, end then defined as rupture or crack subsequent leak, at an unpleasant time with results. The controlling mechanism involved dependent graphitic corros...
