    摘要:

    采用拉伸試驗、硬度測試和光學顯微分析等手段研究了Au-Ti足金的強化機理。結(jié)果表明，Au-Ti足金的強化方式主要是細晶強化、加工硬化和時效強化，且其力學性能優(yōu)于標準的Au917飾品用金合金Au917Ag55Cu28，Au917Ag32Cu51。并且，Au-Ti足金的冷加工性能優(yōu)于千足金，這是由于其固溶態(tài)硬度、強度高，延性好。

    Abstract:

    Strengthening mechanism of Au990-Ti jewelry alloys has been studied systematically bY means of tensile test, hardness test, optical microscopic analysis. Results show that strengthening modes of Au990-Ti jewelry alloys mainly cover grain refining strengthening, work hardening and aging strengthening, and that their mechanical properties are superior to those of standard An917 jewelry alloys, that is, An917Ag55Cu28 and Au917Ag32Cu51. In addition, Au990-Ti jewelry alloys are of better cold workability than pure gold, because of high hardness and strength, good ductility in the solid solution state.
