    摘要:

    研究了含約０．２％（質(zhì)量分?jǐn)?shù)，下同）鑭和釔的銀合金飾品材料的硬度隨變形量、溫度及淬火時效工藝的變化規(guī)律，并用電子探針對銀飾品材料進(jìn)行掃描分析。發(fā)現(xiàn)微量稀土加入銀中可以提高材料的硬度和抗回復(fù)軟化能力，經(jīng)過低溫形變熱處理工藝加工的稀土銀飾品材料顯示了更好的效果，可充分發(fā)揮材料的潛力。通過電子探針掃描分析發(fā)現(xiàn)，微量稀土顯著地細(xì)化了銀合金的晶粒，微量稀土以固溶或化合物形式分布在合金中，有效地延緩了合金的回

    Abstract:

    In order to improve the resistance to natural aging and softening, and property stability of ornamental silver, the dependences of mechanical properties of the silver alloyed with 0 12 wt%(La+Y) on aging temperature have been studied. The experimental results show that the hardness and resistance to softening of Ag can be improved by the addition of small amounts of rare earth elements. SEM analysis indicate that significant grain refinement result. The rare earth additions effectively defer the recovery and recrystallization of silver, thereby improving the resistance to natural aging and softening, and increasing the repeatablility of property.
