Abstract

Abstract

In this paper, the effect of titanium content on the microstructure and properties of non oriented electrical steel with different titanium content was studied by means of annealing furnace, transmission electron microscope, metallographic observation and magnetic property test. The results showed that the grain size of electrical steel decreased with the increase of titanium content. When the content of titanium was less than 0.015%, the grain was equiaxed with a higher uniformity. The titanium precipitated in the form of carbonitride and was pinned at the grain boundary of the structure. With the increase of Ti content to more than 0.015%, the grains in the microstructure were obviously deformed, and Ti precipitated out of the grain boundary and in the grain boundary by Fe-Ti phosphide. The magnetic induction and iron loss of electrical steel could be slightly improved by adding a small amount of titanium ( ≤ 0.015%). The iron loss W_{15 / 50} was about 4.6～5.2 W/kg, and the magnetic induction B₅₀ was about 1.74～1.76 T. However, excessive addition of titanium should be strictly avoided.
