High Chromium Cast Iron: Part Two

High chromium cast irons (HCCI’s) exhibit very good mechanical properties and offer benefits for a range of manufacturing applications.
One of the main flexibilities exhibited is the possibility of HCCI’s to have different matrix structures in different treatment states whether it be austenite in casting state, pearlite in annealing state, martensite in quenching state, and tempered martensite in tempering state.

Metallography: Part One

Microstructural examinations and visual evaluations of fracture surfaces provide an invaluable insight into the mechanism of component and assembly failures.
Typically, the metallography process uses sample specimens removed and mounted in bakelite plastic. The specimens are then ground to a fine finish with sandpaper and then polished to a mirror finish with diamond or alumina polishing materials.

The Rheo Casting Process

Defects and anomalies are an everyday challenge within the framework of foundry technologies. As demand for castings with very specialized applications rises, the issue of quality becomes more important.
The Rheo Casting process involves using slurry in a semi solid state with the amount of benefits directly linked to the fraction solid at the time of casting. Advantages can include a reduction in shrinkage and significantly reduced latent heat.
