以生铁为原料,采用氢化钛(Ti H2)粉末作为发泡剂,利用高真空电弧熔炼及单辊旋淬甩带系统在真空条件下用铜模铸造法制备了圆柱状的铁基泡沫金属。结果表明,随着Ti H2配比的增大,样品的气孔逐渐增多,样品的硬度和压缩断裂强度呈逐渐降低趋势。但当Ti H2配比为5%时,样品的气孔减小,而样品的硬度和压缩断裂强度则增大。 The pig iron was used as raw material, titanium hydride (TiH2) powder was used as foaming agent, and the columnar iron-based foamed metal was prepared by high-vacuum arc melting and single-roller spin-quenching rejection system under copper casting. The results show that with the increase of the ratio of Ti to H2, the pores of the sample gradually increase, and the hardness and compressive rupture strength of the sample decrease gradually. However, when the ratio of Ti to H2 is 5%, the porosity of the sample decreases while the hardness and the compressive rupture strength of the sample increase.
