To gain a deeper understanding of the dynamic accommodation mechanism internal stress in pearlite originating from lattice misfit between ferrite and cementite phases, parameter ratios cementite, bθ/aθ cθ/aθ, were locally analyzed detail using electron backscatter diffraction (EBSD) technique. The EBSD analysis revealed that lamellae clearly differed those spheroidized particles, indicating has...

Abstract 30MnB5 boron alloyed steel surface is coated using different coating techniques, namely 60(Ni-15Cr-4.4Si-3.5Fe-3.2B 0.7C)-40(WC 12Co) metallic powder plasma spray, Fe-28Cr-5C-1Mn alloy wire arc WC-10Co-4Cr (thick) high velocity oxy-fuel (HVOF), and (fine) diamond jet HVOF. The microstructure of the crude sample consists ferrite pearlite matrices iron carbide structures. intermediate bi...

Microstructural morphology is known to have a significant impact on the mechanical properties of dual-phase steels. A fine ferrite grain size and random distribution small second phase islands are desirable provide superior isotropic compared banded that typical for this type steel. rapid alloy prototyping (RAP) facility has been used investigate three different DP 800 variants by systematicall...

Via traditional wire drawing, the medium carbon ferrite-pearlite (MCFP) steel wires can achieve ultrahigh strength beyond 4 GPa normally for high-carbon pearlitic wires, but have a 30–60% lower production cost. The microstructural evolution and mechanical properties of been investigated by means scanning electron microscopy, transmission microscopy tensile testing. increases from 750 MPa up to ...
