The effect was studied of quenching at different temperature on microstructure and hydrogen storage properties of 40Ti-40V-10Cr-10 Mn alloy.The results show that the unquenched sample is V-based solid solution with body centered structure having two close characteristic diffraction peaks of BCC-1phase and BCC-2phase.The sample quenched at 1 473 Khas a single BCC-1phase.Both the samples quenched at1 573 Kand 1 673 Kconsist of BCC-1phase,BCC-2phase and C14-Laves phase with hexagonal closepacked structure.The results of kinetic mechanism study show that the hydrogen absorption kinetic process of all the samples can be described by chemical reaction mechanism,while their equations of kinetic mechanism are significantly different and thus their hydrogen absorption rates are different.With the increase of quenching temperature of the samples,their hydrogen absorption capacity at 298 K decreases firstly and then increases（getting the minimum at 1 573 Kand the sample quenched at 1 673 Kclose to the unquenched sample）,their hydrogen desorption capacity and hysteresis at 298 Kare gradually improved,and their hydrogen desorption capacity at 373 Kalso decreases at first and then increases（getting the minimum at 1 573 Kand the sample quenched at 1 673 Khigher obviously than the unquenched sample）.
