Laser additive manufacturing (LAM) technology can achieve the large-complex components of ultra-high strength steel with high performance
and can also be used for rapid repairing the damaged parts
which is widely used in aerospace and other fields. This paper introduces the forming characteristics of laser additive manufactured low alloy high strength steel
and the influence of the heat accumulated on the microstructure of the LAMed low alloy high strength steel. The mechanism of the microstructure and heat treatment on mechanical properties of LAMed low alloy high strength steel and the application of LAM in repairing ultra-high strength steel are described. The development trends of LAM ultra-high strength steel are prospected.
