Effect of Temper on Deformation and Mechanical Behaviors The effect of tempering (673 K for 30 min) on the microstructure and tensile properties of laser melt-deposited (LMD) 12CrNi2 low-alloy steel is studied. The results show that LMD 12CrNi2 mainly consists of the ferrite and some Cr<SUB>23</SUB>C<SUB>6</SUB> carbides. Characterization of the Schmid factor near the fracture surface shows that after tempering, the slip system with the largest
Some researches revealed that additions of different elements like Ce into deposited alloy in laser remanufacturing of 12CrNi2 steel may improve mechanical properties . Recently, Zhou et al. have investigated the effect of laser power on bainite evolution and mechanical properties of 12CrNi2 alloy. They found that the bainite morphologies depend on the laser power and the sample fabricated at
Effects of Substrate Preheating Temperatures on the The 12CrNi2 alloy steel powder studied in the present paper is mainly used to manufacture camshafts for nuclear power emergency diesel engines. Laser cladding deposition is of great significance for the manufacture of nuclear power emergency diesel camshafts, which has the advantages of reducing material cost and shortening the manufacturing cycle. However, due to the
Enhancement of StrengthDuctility Balance of the Laser Mar 03, 2021 · A ferriteaustenite 12CrNi2 alloy steel additively manufactured by laser melting deposition (LMD) was heat treated by direct quenching (DQ) and tempering inter-critical quenching (TIQ) at 800 °C for enhancing its strengthductility balance.

Study on Fatigue Crack Growth of Laser Melting Deposited Abstract:Based on the Paris model of fatigue crack growth theory, the fatigue crack growth behaviour of Center Crack Tension (CCT) specimens of laser melting deposited 12CrNi2 alloy steel is studied by extended finite element method (XFEM). The crack growth rules and fatigue life are analyzed by experiment and finite element simulation.
Suiyuan CHEN Northeastern University (Shenyang, China The evolution of bainite in the DLD 12CrNi2 alloy steel process at different laser power of 1800 W, 2000 W and 2200 W and mechanical properties of as-deposited samples were investigated. The
