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.

等通道转角挤压(ECAP)技术将用于机械合金化/球磨粉末的固结。该项目的一个直接范围是通过廉价和易碎的机械合金化方法生产非晶态/玻璃合金，并通过ECAP将其固化为块状固体。我们打算用ECAP(使用预合金锭或球磨粉末)制备纳米晶和/或非晶铝合金，表征其组织和力学性能，并建立ECAP机械球磨非晶/纳米晶粉末固结的数学模型。该模型有望阐明ECAP加工在产生所需微观组织中的作用，并有助于优化加工条件。
