Studies on the Weld Cracking of Nodular Graphite Cast Iron (Report 5). Contraction Process and RRC Test of Nodular Graphic Cast Iron Weldments.

Failure Analysis of a Four Cylinder Diesel Engine Crankshaft Made From Nodular Cast Iron

The premature breakage in some four cylinder diesel engine crankshafts was reported. All crankshafts were failed from the same region. Failures had occurred in the first crankpin, the nearest crankpin to the flywheel. Dynamic analysis and finite element modelling were carried out to determine the state of stress in the crankshaft. FEM results revealed that the first crankpin fillet is the most ...

Modeling of Ultrasonic Testing for Inspection of Nodular Cast Iron Insert

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...

Fatigue Behaviour of Synthetic Nodular Cast Irons

A. Vaško, L. Trško, R. Konečná, Faculty of Mechanical Engineering, University of Žilina, Žilina, Slovak Republic The paper shows the influence of charge composition on microstructure, fatigue properties and failure micromechanisms of nodular cast irons. The additive of metallurgical silicon carbide (SiC) in analysed specimens increases the content of ferrite in the matrix, decreases the size of...

Literature search - Deteriorated Graphite Structures on Cast Iron Skins

The fatigue strength offerritic ductile iron, Grade EN-GJS-400-18U-LT. was determined for large section castings measuring 4 by 24 by 24 inches. Fatigue testing was conducted in bending fatigue in order to determine the influence of surface conditions on fatigue strength. Test specimens with various surface conditions were evaluated, including notched and un-notched specimens, as well as those ...
