The high entropy alloys (HEAs) have great potential to be the additives for the B removal from Si. Therefore, the behaviours of the B in Si interacted with CuNiHfTiZr and CuNiTiZr HEAs were investigated. The Zr, Ti, and Hf have strong affinities for B, thus enhancing the formation of borides. The interaction mechanisms of the B and different additives (CuNiHfTiZr and CuNiTiZr) are different. As for the CuNiHfTiZr additive, the B precipitates to form the B particles that are absorbed on the surface of the additive, while the B can also be trapped in the alloy phase and thus formed a homogeneous phase. Except for the two mechanisms mentioned, as for the CuNiTiZr additive, B can react with Ti, Zr and Ni to form borides: (Ti3-xZrx)B4 or Ni3B.

ZrTiHfCuNi高熵合金与硅之间硼的分布行为。

高熵合金(HEA)具有很大的潜力,可以作为从Si中去除B的添加剂。因此,研究了Si中的B与CuNiHfTiZr和CuNiTiZr HEA相互作用的行为。Zr,Ti和Hf对B具有很强的亲和力,因此增强了硼化物的形成。硼与不同添加剂(CuNiHfTiZr和CuNiTiZr)的相互作用机理不同。至于CuNiHfTiZr添加剂,B沉淀形成吸附在添加剂表面的B颗粒,而B也可能被捕集在合金相中,从而形成均匀相。除了提到的两种机理外,对于CuNiTiZr添加剂,B可以与Ti,Zr和Ni反应形成硼化物:(Ti 3-x Zr x)B 4或Ni 3B.
