Abstract
Taken sintered SPN14A7M5 steel as an example and using the mathematic simulation, the effect of porosity on the heat distribution in material during laser processing has been found. The calculated results have been verified by the experimental data. The effect of laser processing on the microstructure and properties of sintered SPN14A7M5 steel has been studied and the optimum conditions of the process have been found.
