旋压工艺与弥散强化铂的塑性变形

THE INFLUENCES OF SPINNING PROCESS ON THE PLASTIC DEFORMATION OF THE DISPERSION STRENTHENED PLATINUM

讨论旋压过程中的应力—应变状态,变形温度—连度及金属的组织结构对弥散强化铂的塑性变形的影响。实验表明,弥散强化铂比纯铂和纯铜更难旋压成型。

The influences of the stress-strain condition suffered in spinning process, temperature-vilocity condition and structure of the material on the plastic deformation of dispersion strengthened platinum were discussed in present paper. The results indicated thai the deformation of the dispersion strengthened platinum by spinning process was more difficult than that of pure platinum and copper.
