Abstract:
This paper presents a comparative analysis of ausferritic ductile cast iron matrix obtained through heat treatment and in its raw state. Ausferrite without heat treatment was achieved by modifying the chemical composition, while nodular graphite was produced using Inmold technology. The presence of compacted graphite in the as-cast ausferritic cast iron was attributed to elements that impede the crystallization of nodular graphite. This study demonstrates that an ausferritic matrix in ductile cast iron can be achieved by incorporating molybdenum in conjunction with nickel or copper. Thermal an

There is a need for cast irons with a combined combination of properties in modern conditions. Such properties can be provided by ductile cast iron with nodular and vermicular graphite, which is essentially a hybrid cast iron in terms of microstructure. The article found that ductile iron with nodular and vermicular graphite in terms of its mechanical properties is a rational alternative to malleable cast iron, namely the grade KCh45-6 (GOST 1215-79). Also, the ratio of nodular/vermicular graphite (70…95/5…30%) was determined, which provides the data of mechanical characteristics. Differences

This article is analyzing the prospects and ways to expand the field of applying ductile cast iron-high-strength cast iron in technology. Ductile cast iron occupies a special place among structural materials. With the same level of mechanical properties, having less specific weight than steel, it provides less weight of products in comparison with steel. This reduces the consumption of raw materials and energy resources in the manufacture and operation of machines and mechanisms. There is a positive effect both in terms of economy and ecology.

Abstract:
Absrract Four 48-inch diameter cast iron outfall pipelines were inspected and rehabilitated in the San Francisco Bay. The inspections included internal and external inspections, pipe structural supports and the ductile iron diffusers. Visual and ultrasonic thickness inspections were conducted on the pipe exterior. Internal inspection was conducted by divers. Rehabilitation included removal of the existing mortar lining and relining of the pipe with an epoxy system and implementation of cathodic protection on the pipe external surfaces. This case study describes the testing and inspection proce

Abstract:
Abstract The Tualatin Valley Water District located west of Portland, Oregon manages a system of nearly 800 miles (over 1200 km) of pipe comprised of approximately 95% iron pipe. 75% of iron pipe is ductile iron and 25% is cast iron. Iron pipe in its system is failing due to external corrosion in as little as 30 years. The district began investigating conditions, installation practices, or circumstances that lead to the corrosion. The district reviewed and evaluated various industry standards and recommendations related to corrosion protection for iron pipe. Based on its review and some of its
