| 1 | Improving chill control in iron powder treated slightly hypereutectic grey cast irons显示文摘Recent studies revealed that in eutectic to slightly hypereutectic grey irons(CE = 4.3%-4.5%) the presence of austenite dendrites provides an opportunity to improve the cast iron properties,as a high number of eutectic cells are 'reinforced' by austenite dendrites.An iron powder addition proved to be important by promoting dendritic austenite in hypereutectic irons,but was accompanied by adverse effect on the characteristics of potential nuclei for graphite.The purpose of the present paper is to investigate the solidification pattern of these irons.Chill wedges with different cooling moduli(CM = 0.11-0.43 cm) were poured in resin bonded sand and metal moulds.Relative clear /mottled /total chill measurement criteria were applied.Iron powder additions led to a higher chill tendency,while single inoculation showed the strongest graphitizing effect.The various double treatments show an intermediate position,but the inoculant added after iron powder appears to be the most effective in reducing base iron chill tendency,for all cooling moduli and chill evaluation parameters.This performance reflects the improved properties of(Mn,X)S polygonal compounds as nucleation sites for graphite,especially in resin bonded sand mould castings.Both austenite and graphite nucleation benefit from a double addition of iron powder + inoculant,with positive effect on the final structure and chill tendency. | Iulian Riposan Mihai Chisamera Stelian Stan Michael Barstow | 2011 | China Foundry2011，8，2： | 2 |

| 17 | 作为深度函数的高频地震噪声显示文摘本文提出的证据支持高频地震噪声随着深度的增加而减少的观点。在面波噪声、人文噪声和自然(风引起的)噪声起主要作用的自由面附近噪声振幅比较高。数据是在纽约北部的阿迪朗达克西北部低洼地的硬岩石场点采集的。在15和40Hz之间,这个点地表的噪声水平比在945m深处的噪声水平高10dB以上,且从40到100Hz,这个差大于20dB。此外,还表明频谱的时间变化在地表处比在335m或945m处要大。地表和地表下噪声变率之间的差异可能部分地与风引起的噪声有关。正交运动分量之间的相干性测量表明,高频地震噪声在地表处比在深处的相干性要高。不同垂直偏移处相同运动分量之间的相干性测量表明了一个在至少可达945m的垂直偏移范围内存在强低频相干性。随垂直偏移减少,具有高相干性的频带变宽。 | J.
