从第12届世界钛会可以看出.传统钛粉末冶金即冷压烧结在降低钛制品的制造成本和改进烧结钛制品的成分及显微组织方面已有了许多可喜的进展。结合第12届世界钛会有关钛粉末冶金方面的研究报告,主要从钛粉体烧结过程中氧和残留氯化物的左除和控制、使用氧化钛粉的优点、通过控制氧化钛粉烧结过程相变制备出具有超细(砸微米至几个微米)显微组织特征的高性能钛材料、合金元素含量扇钛合金的烧结特点、微波辐射烧结钛及钛合金几个方面讨论了钛粉末冶金褶关研究的最新进展。
The 12th World Conference on Titanium has seen the presentation of a number of noteworthy developments that were aimed at achieving cost reductions and/or improved constitu- tional and microstructural capabilities through the conventional cold-compaction-and-sinter powder metallurgy (PM) approach. This review discusses several such developments, including the scavenging of oxygen and chlorine from Ti powder compacts during sintering by minor additions of rare each compounds, the advantages of PM Ti fabrication with TiH2 powder over elemental Ti powder, the efforts to develop uhrafine as-sintered microstructures from the use of TiH2 powder, the design of sintering pathways for high solute content alloys such as Ti-10V-2Fe-3Al, and the positive implications of microwave-assisted sintering of commercially pure (CP) Ti and Ti alloys.
