Influence of Several Heat Treatments on Residual Stress in Laser Powder Bed-Fused Maraging 18Ni-300 Steel
نویسندگان
چکیده
In laser powder bed fusion, process-inherited thermal residual stress is developed due to the strain misfit between each layer. Detailed analysis and a prediction of are needed because it can induce distortions components and, in some serious cases, stress-induced defects such as cracking. this work, effects heat treatment conditions on maraging 18Ni-300 steel, fabricated by were investigated. Cantilever-shaped specimens used experimentally analyze caused while cutting them from supporters. The cantilever samples showed complex distortion behavior as-built state. They bent downward supporter when thickness was relatively thin, bending deformation became upward instead with increasing thickness. Interpreting finite element simulation that compressive state at top layer steel. When aging treated, significantly reduced, implying diminished.

Investigation into heat treatment and residual stress in laser clad AA7075 powder on AA7075 substrate
The laser cladding of AA7075 powder onto a AA7075 substrate was conducted to evaluate the effect of heat treatment and measure residual stress between the clad layer and substrate in order to better understand the effect of laser cladding. The microstructure formed in the clad region was characteristic of a high cooling rate, which is typical for laser cladding. The heat affected zone showed co...

In the present work, the influence of aging temperature on mechanical properties and sound velocity of Maraging steel M350 was investigated. For this purpose, first, samples were solution annealed at 825◦C for 2 hours and then age hardened at 510◦C-600◦C for 3 hours. Hardness, tensile and impact tests were used for determining mechanical properties and longitudinal ultrasonic velocity was used ...
