以Al-Mg为基的合金在工业上有广泛的用途,近年来人们为提高其加工性和强度,往往又添加适量的稀土元素,特别是加微量的钇可提高合金的高温强度,所以测定Al-Mg-Y合金系统的相图是具有实用意义的。本文用X光品格参数方法测定了含钇0.1wt％和0.2wt％的Al-Mg合金相图中富铝角的相边界,这是完全基于实用的考虑,因为工业上广泛应用的合金大都在这个成分区域内。
Al-Mg-based alloys have a wide range of industrial applications. In recent years, people often add appropriate amounts of rare earth elements to improve their workability and strength. In particular, adding a small amount of yttrium can increase the high temperature strength of the alloy. Therefore, Al-Mg-Y alloy system phase diagram is of practical significance. This article uses the X-ray character parameter method to determine the phase boundary of the Al-Mg alloy phase diagram with 0.1wt% yttrium and 0.2wt% Al-Mg alloy phase angle, which is based entirely on practical considerations because most of the industrially used alloys are mostly in this Within the component area.
