Grey cast iron is characterized by its graphitic microstructure. Most cast irons have a chemical composition of 2.5 to 4.0% carbon, 1 to 3% silicon, and the remainder is iron. Nodular or ductile cast iron is a more recent development. Tiny amounts of magnesium or cerium added to these allo...
The factors influencing the cutting machinability ofgray ironcylinder blocks were summarized including chemical composition, melting and inoculating processes, graphite and hard particles in the matrix. 综述了影响灰铸铁缸体切削加工性的因素,包括化学成分、熔炼及孕育处理方法、石墨和基体组织中的硬质点。

How was grey/mottled cast iron produced? As mentioned above, the major difference between grey/mottled cast iron and white cast iron is the presence of flake graphite. Its formation as well as the morphology and distribution pattern largely depend on the chemical composition (alloying elements) of...
The Cu-Ni alloy cast irons of different chemical constitution were designed,and the corrosion rate in room-temperature concentrated alkaline solution was measured by the static hydrometer method,the microscopics and phase composition of alloy cast iron were observed by optical microscope and XRD. 设...
