Microstructure evolution and mechanical properties of1 000 MPa cold rolled dual-phase steel ZHAO Zheng-zhi(赵征志), JIN Guang-can(金光灿), NIU Feng(牛 枫), TANG Di(唐 荻), ZHAO Ai-min(赵爱民) Engineering...; Abstract: The microstructure evolution of 1 000 MPa cold rolled dual-phase (DP......
compound. The growth of intermetallics on the composite interface of Ni-Al cladding strip was studied at different annealing temperatures. The results show that the intermetallics form firstly and grow rapidly in certain zones on the interface under proper thermodynamics conditions and then the intermetallics is jointed to a whole layer. The thickness of the intermetallic layer increases......

sheets fabricated under different reduction ratios between 30% and 65% were verified by transmission electron microscopy (TEM). Taking the difference of interface microstructure into consideration, 3-point... is strongly correlated with the interface microstructure. This was especially verified by observing the interface delamination from the 3-point bent samples. Key words: Al/Cu 2-ply composite; flexural......
