| 2 | Synthesis and characterization of copper foams through a powder metallurgy route using a compressible and lubricant space-holder material显示文摘In the present work,a compressible and lubricating space-holder material commonly known as 'acrawax' was used to process Cu foams with various pore sizes and various porosities.The foams were processed without using binders to avoid contamination of their metal matrices.The lubricant space-holder material was found to facilitate more uniform flow and distribution of metal powder around the surface of the space holder.In addition,the use of acrawax as a space-holder material yielded considerably dense cell walls,which are an essential prerequisite for better material properties.The foams processed with a smaller-sized space holder were found to exhibit better electrical and mechanical properties than those processed with a coarser-sized space holder.The isotropic pore shape,uniform pore distribution throughout the metal matrix,and uniform cell wall thickness were found to enhance the properties pertaining to fine-pore foam samples.The processed foams exhibit properties similar to those of the foams processed through the lost-carbonate sintering process. | Mohit Sharma O.P.Modi Punit Kumar | 2018 | International Journal of Minerals,Metallurgy and Materials2018，25，8： | 0 |
| 3 | 冲击角度与旋转速度对铝冲蚀行为的影响(英文)显示文摘将工业纯铝暴露在一定浓度的泥浆中,样品以不同的角度固定,并在不同速度下旋转,通过质量损失来测量样品的磨损率。结果表明,当冲击角度小于90°时,样品的磨损率随冲击角度的增加而增加。与传统的认识不同,铝的最大磨损率出现在冲击角为90°,而不是出现在冲击角45°。旋转速度的增加将导致磨损率呈指数增加。这一结果与磨损表面的金相分析一致。 | A.K.JHA R.BATHAM M.AHMED A.K.MAJUM DER O.P.MODI S.CHATURVEDI A.K.GUPTA | 2011 | Transactions of Nonferrous Metals Society of China2011，21，1： | 0 |
