摘要

The effect of the amount of cold reduction and annealing temperature on the evolution of the texture of AISI 441 steel is reported. The steel was cold rolled by 62%, 78%, and 82%, followed by isothermal annealing of each sample at 900°C, 950°C, and 1025°C for 3 minutes. The crystallographic texture was determined by Phillips X'Pert PRO MPD texture diffractrometer. Microstructures were characterized using optical microscopy and scanning electron microscopy (SEM). The results show that sample that received 78% cold reduction and annealing at 1025°C presented the highest R_m -value and lowest ΔR-value, which would enhance its deep-drawing capability. In addition, this sample showed the highest intensity of shifted Y-fibre, notably {554}<225> and {334}<483>. It can therefore be concluded that the γ-fibre, which favours deep drawing, is optimal after 78% cold reduction and annealing at 1025°C.
