塑性变形时金属内部产生许多新的位错结构,同时使金属内部的能量激增,因而促使一切与扩散有关的转变过程加速进行,许多研究工作证明冷工变形对可时效的合金的影响尤大。斯维斯多诺娃在研究冷轧对镍基合金的组织及性能的影响时,证明在塑性变形时过饱和的固溶体就进行了部分分解,而当时效过程中固溶体的分解尤为迅速。最近几年来,许多人都在研究冷工变形对耐热钢及合金的组织及性能的影响,这些研究工作一方面有助于寻求较合理的加工方法,从而提高它们的耐热性能(特别有些另
During plastic deformation, many new dislocation structures are generated in the interior of the metal, and meanwhile, the energy in the interior of the metal is greatly increased. As a result, all the diffusion-related transformations are accelerated. Many researches have proved that cold working deformation has a great influence on the age-hardenable alloy. When studying the effect of cold rolling on microstructure and properties of Ni-based alloys, Svydordova proved that supersaturated solid solutions undergo partial decomposition during plastic deformation and solid solutions decompose more rapidly during aging. In recent years, many people are studying the impact of cold working deformation on the microstructure and properties of heat-resisting steel and alloy. These researches can help to find more reasonable processing methods to improve their heat resistance (especially some another
