TopicEffect of heat treatment on microstructure and tribological characteristics of the samples produced by the method of additive manufacturing
The work established that the heating the samples to a temperature of 1050 C (1.5 hr exposure) obtained by direct application of the laser leads to increased wear resistance. Reduced strength is achieved through the provision of grain carbide phases. The structural zone formed during LMD. It was found that the cross-sectional structure of the samples consists of alternating columnar and small zones variously oriented crystals.
