Nodular cast iron insert will be used as the inner component of nuclear fuel disposal canister. The outer cover of the canister is copper tube of 50 mm nominal thickness. Nodular cast iron insert is cast around several steel channels, which also strengthen the structure. The mechanical properties of the cast iron insert will be tested according EN-1563 /1/. According the specifications 100% NDT...

Particulate reinforced metal matrix composites (MMCs) are potential materials for various applications due to their advantageous of physical and mechanical properties. This paper presents a study on the performance of stir cast Al2O3 SiC reinforced metal matrix composite materials. The results indicate that the composite materials exhibit improved physical and mechanical properties, such as, lo...

Pipe failures are a common problem for all water utilities. This paper describes a step by step approach for determining the causes of those failures. This process is particularly important for investigating failures in important pipelines where the failure may have had significant social or economic costs. The steps presented include actions that should be taken to prepare for a failure analys...

Ni-Hard4 white cast iron is excellent wear resistant material and has been widely used in wearaffected equipment operated under extreme conditions, such as in mineral processing, cement, copper and iron manufacturing. In this study the effect of titanium addition (1.2, 0.7 and 0.2 wt.%) to the Ni-hard 4 cast iron with the nominal composition of Si= 1.5%, Mn=0.5%, C=3%, P=0.05%, S= 0.05%, Mo= 0....

Tantalum Carbide (TaC) reinforcement was made to lamellar graphite (gray) cast irons that were produced in the physical conditions of a foundry at ratios 0%, 0.025%, 0.155%, and 0.285%. Samples complying with standards prepared using TaC-reinforced iron alloys produced, Brinell hardness tests, compressive strength microstructural analyses conducted. According test results, highest average value...

In presented work authors analyzed the high-temperature oxidation process from the point of view of its influence on effects obtained during cast iron hot-dip zinc coating. Research concerned the influence of the high-temperature oxidation, as a preliminary stage previous to coating with zinc on the change of surface layer structure as well as subsurface layer of cast iron with flake, vermicula...

Industrial and experimental induction furnaces are used for melting various types of iron ingots, returned scraps and DRI sponge pellets to produce high purity cast - iron and steel heats. The lowest consumption of electrical energy determined for continuous feeding operation is 0.3 KWH/Kg for the production of cast - iron in a 1.5 - ton industrial furnace and 0.45 KWH/Kg for the production of ...
