Damping Behaviour of High Silicon Nodular Cast Iron

چکیده

Abstract This work focused on producing and characterizing high silicon cast irons (microstructural analysis, tensile properties, damping capacity, elastic properties). Moreover, it also evaluated the influence of RE alloying capacity. The samples present a step-casting geometry to verify cooling rate’s impact their microstructures and, consequently, mechanical properties. Si SGI presented fully ferritic matrix ( i.e. pearlite < 5%) with uniform dispersed graphite nodules; however, those alloyed showed lower nodularity. results show an average increase, relative base SGI, 33% for strength 55% yield (section thicknesses between 45 25 mm). A capacity increase was observed, reaching maximum 32% addition RE. beneficial lies in possibility increasing without compromising its strength, by balancing degeneration (induced alloying) strengthening (promoted content).

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...

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 ...

Tribological Behavior of Reinforced and Unreinforced High Chromium Cast Iron

In this paper, the metal matrix composites containing 22 wt % Cr, 2.5 wt % C and 2 to 16  volume percent TiC were processed by solidifying Fe-Cr-Ti-C in which precipitation of titaniumcarbide and chromium carbide occurred. The microstructure and abrasion resistance of in-situ synthesized composites were compared with the unreinforced high chromium white cast iron (HCWCI) containing 22 w. t. % C...
