Abstract The low melting point tin-zinc (Sn-9Zn) alloy foam was successfully prepared by direct foaming method. Titanium hydride and calcium are proved to be practicable as blowing agents and melt foam stabilizers respectively. The microstructure investigation on cell walls indicated that the formation of calcium stannate (CaSnO3) plays a key role in cell wall formation and bubble stabilization, apart from the particles derived from foaming agents. Quasi-static compressive curves of Sn-Zn alloy foams are characterized by three stages: elastic deforming, large plastic deforming and densification stage, indicating an outstanding energy absorption capability.

锡锌合金泡沫的制备

摘要 采用直接发泡法成功制备了低熔点锡锌(Sn-9Zn)合金泡沫。氢化钛和钙分别被证明可用作发泡剂和熔体稳泡剂。对细胞壁的微观结构研究表明，除了来自发泡剂的颗粒外，锡酸钙 (CaSnO3) 的形成在细胞壁形成和气泡稳定中起着关键作用。Sn-Zn 合金泡沫的准静态压缩曲线具有三个阶段：弹性变形、大塑性变形和致密化阶段，表明具有突出的能量吸收能力。
