An additively manufactured (AM) FeNiCoCr-based multicomponent alloy (MCA) with prominent cellular dislocation structures was produced using the laser powder-bed fusion (LPBF) method. Creep tests were conducted on the alloy at a high temperature of 650 degrees C by a tensile stress of similar to 100 MPa for more than 100 h, and a significantly low creep strain of less than similar to 0.023 was attained at the end of the test. It is found that the cellular dislocation structures exhibit high thermal stability and stabilize the dislocation networks at elevated temperatures, inducing considerable ...
