The brief mechanisms of mechanical alloying are reviewed. The mechanisms of preparing amorphous, nanocrystalline and supersaturated solid solution materials are also reviewed.

阐述了机械合金化的基本原理，金属粉末机械合金化形成非晶、纳米晶和超饱和固溶体的基本机理。

Hardening and strengthening of metals that result from alloying in which a solid solution is formed. The presence of impurity atoms restricts dislocation mobility.

由于形成固溶体的合金化过程引起的金属硬化和强化，其机制是异类原子的存在限制了位错的可动性。
