Butt-jointed Seam Saddle Welding for Clad Plate of Low Content Alloy and Heat-Resistant Steel& Major Diameter Thick-walled Tube 低合金耐热钢复合板与大直径厚壁接管马鞍形对接焊
But too high or too low content of Mg in the alloy is disadvantageous for Al2O3 nucleating and growth. 但在合金中,镁含量太高或太低都对Al2O3的形核和长大不利。
The results show that a low C and Fe content and a complex reaction among proper Ni, Cr, Mo make the alloy possess good resistance to mix acid and intergranular and pitting corrosion. 试验结果表明,低的含碳量与含铁量和适量的镍、铬、钼的复合作用,使该合金对混酸介质具有良好的耐蚀性和较高的抗晶间腐蚀与抗点蚀性能。
Ideas to reduce the producing cost of the key materials of MH/ Ni battery were proposed. A novel technology of rapid solidifying casting trip was used to produce low content of Co and high specific capacity hydrogen storage alloy. 提出了降低MH/Ni电池负极、正极及泡沫镍等关键原材料的生产成本,保持其优良性能的一系列创新性的思想,即采用快冷厚带新工艺生产低Co、高比容贮氢合金;
The results show that the addition of Ru into the cast nickel base superalloy with low content of Cr and high content of W does not affect liquidus temperature of alloy, but can influence the precipitation temperature of primary MC carbide and eutectic γ+ γ′ obviously. 结果显示:Ru的加入对低Cr高W铸造镍基高温合金的液相线温度无明显影响,但对初生MC碳化物以及γ+γ′共晶的析出温度有明显作用。
Analysis of Super Low-carbon Content in High Alloy 高合金钢中超低碳分析
Although the craft is feasible, the current efficiency is somewhat low, the technical conditions are to be optimized. Finally, the carbon content analysis experiment of Gd-Fe alloy has been carried out. 最后,对制得的钆铁合金进行了碳含量的分析实验。
