采用微触变成形工艺制备了一种高硬度耐磨坩埚颗粒冶金工具钢。与特殊的半固态成形过程中的显着的微观结构的修改,其特征在于详细的扫描电子显微镜和X-射线衍射。材料的机械性能通过组成相的纳米压痕在触变成形前和触变成形后进行评估。本文首次讨论了微触变成形所引起的新的显微组织变化,这有利于进一步提高钢的硬度。
We report on mini-thixoforming of a hard and wear-resistant crucible particle metallurgy tool steel. Significant microstructural modifications associated with the special semisolid forming process are characterized in detail by scanning electron microscopy and X-ray diffraction. The mechanical performance of the material is assessed both pre-thixoforming and post-thixoforming by nanoindentation of the constituent phases. The novel microstructural changes that result from mini-thixoforming, which are discussed in this article for the first time, are beneficial in further improving the hardness of the steel.
