4.The test of 8 pass cold extrusion of equal channel angular pressing (ECAP) with ratio of extrusion reduction 1.02 of each pass for 00Cr18Ni12 austenite stainless steel has been carried out.
5.Effect of Annealing Temperature on the Microstructure of Fe-based Shape Memory Alloy After Two Passages ECA Pressing
6.When the deformation of the workpiece exceeds permission of one step, the wrinkling defect will be produced, the multi-steps forming can resolve the problem.
7.The analysis of the distributions of simulated strain and velocity shows that the fins are multi-step local deformed.
8.After four ECAP passes, tensile strength reaches 420MPa, which is ~3 times than that of as-annealed state, the ductility is -30% and then be saturated.
9.For the two stages brass tube with high aspect ratio, there are many challenges in the front of tool makers.
10.This paper introduces the experiences of production angle bars of over 3 # and screw steel by using 120mm×120mm continuous casting square slab and twelve passes dividing rolling technology?
