Influence of Microstructure on Static and Cyclic Fracture Toughness of EN-GJS-600-3 Nodular Cast Iron

Effects of Silicon on Mechanical Properties and Fracture Toughness of Heavy-Section Ductile Cast Iron

The effects of silicon (Si) on the mechanical properties and fracture toughness of heavy-section ductile cast iron were investigated to develop material for spent-nuclear-fuel containers. Two castings with different Si contents of 1.78 wt.% and 2.74 wt.% were prepared. Four positions in the castings from the edge to the center, with different solidification cooling rates, were chosen for micros...

Influence of Nb on the Microstructure and Fracture Toughness of (Zr0.76Fe0.24)100−xNbx Nano-Eutectic Composites

The present study demonstrates the evolution of eutectic microstructure in arc-melted (Zr0.76Fe0.24)100-xNbx (0 ≤ x ≤ 10 atom %) composites containing α-Zr//FeZr₂ nano-lamellae phases along with pro-eutectic Zr-rich intermetallic phase. The effects of Nb addition on the microstructural evolution and mechanical properties under compression, bulk hardness, elastic modulus, and indentation fractur...

The Microsegregation Pattern of Aluminum and Silicon in the Matrix Microstructure of the Nodular Cast Irons

Characterisation of the Cyclic Deformation Behaviour of the Nodular Cast Iron ASTM 80-55-06 on the Basis of Physical Measurement Methods

The current paper is focussed on the nodular cast iron ASTM 80-55-06 (EN-GJS-600). The individual microstructure was investigated by light and scanning electron microscopy as well as micro-hardness measurements. Stress-controlled fatigue tests were performed at ambient temperature with testing frequencies of f = 5 Hz and f = 150 Hz. The cyclic deformation behaviour was characterised by means of...
