一种掺杂Ca、Ho的镁合金的制备方法
摘要：
本发明涉及一种掺杂Ca、Ho的镁合金的制备方法，是以镁、铝为原料，添加镁-钙中间合金、镁-钬中间合金，在真空熔炼炉熔炼，在氩气保护下浇铸成锭，经切制、低温回火，制成掺杂钙、钬的镁合金锭，此制备方法工艺先进、配比合理、数据翔实精确，不污染环境，安全稳定可靠，制备的掺杂Ca、Ho的镁合金金相组织致密，在室温25℃下的抗拉强度达到278MPa、屈服强度达到167MPa、伸长率为5.50%，是十分理想的制备掺杂钙、钬的镁合金的制备方法。
摘要（英）：

The invention relates to a preparation method of a Ca and Ho-doped Mg alloy. The preparation method comprises the following steps of: using Mg and Al (Aluminum) as raw materials, adding an Mg-Ca intermediate alloy and an Mg-Ho intermediate alloy, melting in a vacuum melting furnace, casting under the protection of argon to form ingots, and preparing Ca and Ho-doped Mg alloy ingots by cutting and low-temperature tempering. The preparation method of the Ca and Ho-doped Mg alloy is advanced in process, reasonable in proportion, detailed and accurate in data, environment-friendly, safe, stable and reliable; the prepared Ca and Ho-doped Mg alloy is compact in metallographic structure, and has a tensile strength up to 278MPa, a yield strength up to 167MPa and an elongation of 5.5% at a room temperature of 25 DEG C, so that the preparation method of a Ca and Ho-doped Mg alloy is ideal.
