【摘要】：研究了球磨對氣霧化法所制備的Zr_(50.7)Cu_(28)Al_(12.3)Ni_9金屬玻璃粉末結(jié)構(gòu)與吸放氫性能的影響。氣霧化的金屬玻璃粉末在經(jīng)過80 h的球磨后,仍呈現(xiàn)為非晶態(tài)。球磨對金屬玻璃粉末吸放氫性能的影響在一臺全自動Sieverts裝置上進(jìn)行了測量。球磨之后,金屬玻璃粉末的吸氫性能獲得提升,粉末的飽和吸氫質(zhì)量分?jǐn)?shù)從霧化態(tài)的0.96%(H/M≈0.7)提升至了球磨后的2.66%(H/M≈1.9)。然而,由于吸氫后金屬玻璃粉末內(nèi)部生成穩(wěn)定的氫化物相,使得球磨后的金屬玻璃粉末的放氫性能未能獲得提升。
[Abstract]:The effect of ball milling on the structure and hydrogen absorption and desorption properties of Zr_ (50.7) Cu_ (28) Al_ (12.3) Ni_9 metallic glass powder prepared by atomization method was studied. After 80 h ball milling, the gas atomized metallic glass powder still shows amorphous state. The effect of ball milling on hydrogen absorption and desorption of metallic glass powder was measured on an automatic Sieverts device. After ball milling, the hydrogen absorption properties of metallic glass powder were improved, and the saturated hydrogen absorption mass fraction of the powder increased from 0.96% (H 鈮，
