详细论述了烧结金属材料金相样品的制备方法和金相样品制备过程中可能产生的问题以及控制和消除它们的方法。依此方法可确保获得一个平整的、能反映烧结金属材料真实显微组织和结构的金相样品。
The preparation methods of metallographic samples of sintered metal materials and the problems that may arise during the preparation of metallurgical samples are discussed in detail, and the methods of controlling and eliminating them are discussed. In this way, a flat, metallographic sample that reflects the true microstructure and structure of the sintered metal material is ensured.
