performance [1]. Among various tube bending methods such as stretch bending, roll bending, compress bending and push bending, the numerical control (NC) bending is the unique one to incrementally obtain the HS-TA18 bent tubes due to high precision, high efficiency, low consumption and automation advantages [2]. However, the NC bending is a complex physical process with multi-die constraints and multi......
October 2016 Abstract: Equal channel angular pressing (ECAP) is one of the most effective processes to produce ultra-fine grain (UFG) and nanocrystalline (NC) materials. Because the commercially pure... temperature by the ECAP process via a channel angle of 135° for 3 passes.
