Expansion during the solidification of gray cast iron was studied by the help of Linear Variable Differential Transformer (LVDT). The chemical composition of the samples was altered by adding two types of inoculant; Superseed (50% Si, 1% Sr and 0.5% Al) and SMZ (69% Si, 1.9% Ca, 0.7%...
The factors influencing the cutting machinability of gray iron cylinder 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。
gray cast ironnitrogensolubilityThe expressions of the dependence of nitrogen solubility in molten gray cast iron on the temperature and composition of the melt were proposed under the condition of foundry practice. Three gray cast iron specimens with different compositions were examined in good ...
22. The gray cast iron of claim 18, wherein the iron has a near-eutectic composition comprising about 3.0 to 4.5% by weight carbon; about 1.0 to 3.5% by weight silicon; up to about 0.8% by weight manganese; about 0.05 to 0.15 wt % sulfur; and less than about 0.1% by weight phosph...
Plasma nitriding methods enable the achievement of thinner layers and better control over the composition [10]. By increasing the reactivity of the medium, the deposition occurs in shorter times and temperatures compared with gas processes [8]. In addition, previous studies have shown that plasma ...
The invention provides a low-chromium copper alloy gray cast iron and preparation method thereof, which relates to the field of material technology. The chemical composition of the low-chromium copper alloy gray cast iron comprises (by weight ratio) carbon 3.15 to 3.55%, sulfur not larger than ...
PURPOSE: To produce a gray cast iron of high carbon content, excellent in mechanical properties and damping characteristic, by performing melting and refining under a high-temp. reducing atmosphere so that an eutectic or hypereutectic composition having respectively specified total carbon content and sil...
A TiC/Al3Ti composite coating on the gray cast iron was fabricated by the reaction synthesis in melt.The microstructure,interface,micro-hardness and wear resistance were investigated.The results show that the composite is formed on gray cast iron compactly with a metallurgical bonding interface.TiC...
