摘要
本文针对MP—159合金的两种不同处理制度所得两种不同显微组织进行透射电子显微镜观察,从而对合金的强化机制进行探讨。结果表明,MP—159合金冷加工产生形变孪晶和hcp相在晶粒中形成互相交织的网络,使得位错很难长距离运动,进而形成高位错密度的胞状结构,产生加工强化,使合金强度显著提高。
The electron micrographic images of two different deformations of MP-159 alloy were observed by TEM, A strengthening mechanism was formed by the network of extremely thin hep platelets and the twins in cold worked alloy. Because of the closely spaced, the intersecting network was developed within each grain, and the movement of dislocations over the large distances would become extremely difficult. This mechanism is explained as a high strength.
