Development and Characterization of Amorphous and/or Nanochrystalline Al Alloys by Equal Channel Angular Pressing

等通道角压（ECAP）技术将用于巩固机械合金/研磨粉末。该项目的一个直接范围是通过廉价和灵活的机械合金化路线生产非晶/玻璃合金，并通过ECAP将其固化成块状固体。我们打算通过ECAP（使用预合金铸锭或球磨粉末）开发纳米晶和/或非晶铝合金，表征微观结构和力学性能，并通过ECAP建立机械研磨非晶/纳米晶粉末固结的数学模型。该模型有望阐明ECAP加工在生产所需微观结构中的作用，并有助于优化加工条件。

Equal channel angular pressing (ECAP) technique will be used for consolidating mechanically alloyed/milled powders. An immediate scope of the project is to produce amorphous/glassy alloys by inexpensive and flecible route of mechanical alloying and consolidate them into bulk solid by ECAP. We intend to develop nanocrystalline and/or amorphous Al alloys by ECAP (using either pre-alloyed ingot or ball-milled powder), characterize the microstructure and mechanical properties and develop a mathematical model of consolidation of mechanically milled amorphous/nanocrystalline powders by ECAP. The model is expected to elucidate the role of ECAP processing in producing the desired microstructure and to help optimizing the processing conditions.
