摘要


本研究主要以機械合金法探討添加Sn、Si、B元素於Cu50Ti40Ni10之非晶質化行為。結果顯示在組成成分(Cu50Ti40Ni10)SnxB5-x (x=0-5)、(Cu50Ti40Ni10)SnxSi5-x (x=0-4)以及(Cu50Ti40Ni10)SixB5-x (x=1、2、4)中可以形成非晶相,並且發現皆存在一寬廣過冷液態區(DT),如(Cu50Ti40Ni10)95B5之DT為58.54 K、(Cu50Ti40Ni10)95Sn1B4為78.47 K、 (Cu50Ti40Ni10)95Sn2B3為71.53 K、(Cu50Ti40Ni10)95Sn4B1為81.05 K、(Cu50Ti40Ni10)95Sn5為78.94 K、(Cu50Ti40Ni10)95Sn3Si2為57.91 K、(Cu50Ti40Ni10)95Sn4Si1為76.58 K以及(Cu50Ti40Ni10)95Si1B4為65.73 K。此外,基於ΔTx的結果,發現添加Sn元素對Cu基合金具有最好的玻璃形成能力,其次為B元素,而Si元素最差。

並列摘要


This study examined the amorphization behavior by adding Sn, B, and Si elements to Cu50Ti40Ni10 alloy powders synthesized by mechanical alloying technique. According to the results, the mechanical alloyed powders were amorphous at compositions (Cu50Ti40Ni10)95SnxB5-x (x=0-5), (C95Snu50Ti40Ni10)95SnxSi5-x (x=0-4), and (Cu50Ti40Ni10)95SixB5-x (x=1, 2, 4). The amorphous powders were found to exhibit a wide supercooled liquid region before crystallization. The temperature interval of the supercooled liquid region (ΔTx) is 59K((Cu50Ti40Ni10)95B5), 78K((Cu50Ti40Ni10)95Sn1B4), 72K((Cu50Ti40Ni10)95Sn2B3), 81K((Cu50Ti40Ni10)95Sn4B1), 79K((Cu50Ti40Ni10)95Sn5), 58K((Cu50Ti40Ni10)95Sn3Si2), 77K((Cu50Ti40Ni10)95Sn4Si1), 66K((Cu50Ti40Ni10)95Si1B4). Besides, based on △Tx, the Sn-additive Cu based alloys have the best glass forming ability, followed by B-additive alloys and then by Si-additive alloys.
