Effect of Heat Treatment on the Microstructure,Mechanical Properties and Corrosion Resistance of Selective Laser Melted 304L Stainless Steel
文献摘要：
The influence of heat treatment holding temperatures from 600 to 1300℃on the microstructure,mechanical properties and corrosion resistance in selective laser melted(SLMed)304L stainless steel is investigated in this work.The results reveal that there is no remarkable microstructure change after holding at 600℃for 2 h,while recrystallization leads to a slight decrease in grain size in the temperature range of 700-900℃.The heat treatment at temperatures from 1000 to 1300℃for 2 h obviously affects the morphology of grains in SLMed 304L stainless steel.Combining effects of grain coarsening,delta-ferrite(8)phases reduction and residual stress release during heat treatment lead to the reduction of yield strength and an increasing elongation.The elongation of the samples heat treated at 800℃for 2 h is,however,significantly decreased due to the increase in the amount of sigma(σ)phase.A remarkable increase in the amount of δ ferrite results in an increase in yield strength but a decrease in ductility after heat treatment at 1300℃for 2 h.The corrosion resistance of the samples heat treated at 1300℃is significantly improved due to the substantial reduction of brittle phase(σ).There is no obvious effect of the presence of 8 ferrite on corrosion behavior.
