摘要
Our previous study has found that FeCrVTi_(x) medium-entropy alloys(MEAs)with BCC matrix and Laves precipitation have high yield strength(1097-1493 MPa),good fracture strain(27.1%-47.7%)and excellent thermal conductivity(42.2-69.7 W/(m·K)at 673-1273 K),it is expected to be widely applied in the elds of advanced nuclear energy and aerospace^([1]).However,what is the mechanism of strengthening and high thermal conductivity of this MEAs?
