为探讨 Fe 元素在锡青铜中的机理行为,本工作是在 Cu-Fe,Cu-Sn 和 Fe-Sn 三个二元系相图基础上,用 X 射线粉末衍射法、金相法和微差热分析法测定了 Cu-Fe-Sn 三元系合金相图的室温截面和600℃等温截面.配制合金所用的材料是纯度为99.99%的Fe 和99.99%的电解 Cu 以及光谱纯的 Sn.每个试样按3g 配料,用感量为0.1mg 的光电天平测量,配料盛于 Al_2O_3坩埚内,在稍大于1个大气压的氩气保护下的高频感应炉中熔炼.熔好后的合金样品呈钮扣状,表面光滑,失重率小于
In order to explore the mechanism of Fe element in tin bronze, this work is based on the phase diagrams of three binary systems of Cu-Fe, Cu-Sn and Fe-Sn. X-ray diffraction, metallography and microtherm analysis Method was used to determine the room-temperature cross-section and the isothermal cross-section of 600 ℃ for the phase diagram of Cu-Fe-Sn ternary alloy.The materials used to prepare the alloy were Fe with 99.99% purity, 99.99% electrolytic Cu and pure Sn, Sample by 3g ingredients, with a sense of the amount of 0.1mg photoelectric balance measurement ingredients Sheng Sheng Al_2O_3 crucible, slightly larger than 1 atmosphere of argon gas under the protection of high-frequency induction furnace smelting alloy sample was a button Button-shaped, smooth surface, weight loss rate is less than
