一种镁合金掺杂SiC颗粒的增强方法
摘要：
本发明涉及一种镁合金掺杂SiC颗粒的增强方法，是针对镁合金模量低、强度低、易磨损、耐高温性能差、热膨胀系数高的情况，采用在熔炼镁合金块过程中掺杂细碳化硅和粗碳化硅颗粒，然后进行浇铸、加压和热挤压成型，大幅度提高镁合金的屈服强度、硬度和耐磨性能，使屈服强度达328MPa±2MPa，硬度达120HV±5HV，耐磨性提高了80%，此方法工艺先进新颖，数据准确翔实，增强效果好，是十分理想的镁合金掺杂SiC颗粒的增强方法。
摘要（英）：

The invention relates to a method for strengthening magnesium alloy by doping SiC particles. Aimed at the low modulus, low strength, easy abrasion, poor high-temperature resistance and high thermal expansion coefficient of magnesium alloy, according to the method, fine silicon carbide and coarse silicon carbide particles are doped in the process of smelting a magnesium alloy block, the melt is then cast, pressurized and formed by hot extrusion, consequently, the yield strength, hardness and wear resistance of the magnesium alloy are greatly enhanced, the yield strength reaches 328MPa plus or minus 2MPa, the hardness reaches 120HV plus or minus 5HV, and the wear resistance is enhanced by 80 percent. The process of the method is advanced and novel, data are accurate and detailed, the strengthening effect is good, and the method is an ideal method for strengthening magnesium alloy by doping SiC particles.
