The low-carbon high-Mn austenitic steel microalloyed with titanium was investigated in this work. The steel was solution heat-treated at different temperatures in a range from 900 to 1200 °C. The aim was to receive a different grain size before the static tensile test performed at room temperature. The samples of different grain sizes showed the different strain hardening behavior and resulting mechanical properties. The size of grain diameter below 19 μm was stable up to 1000 °C. Above this temperature, the very enhanced grain growth took place with the grain diameter higher than 220 μm at 1200 °C. This huge grain size at the highest temperature resulted in the premature failure of the sample showing the lowest strength properties at the same time. Correlations between the grain size, the major strengthening mechanism, and fracture behavior were addressed. The relationships were assessed based on microstructural investigations and fractography tests performed for the deformed samples. The best combination of strength and ductility was found for the samples treated at 1000–1100 °C.

Ultrasonic Action

The relationship between N and strain hardening exponent curve are obtained by the tensile test of the stainless steel, low carbon steel, medium manganese steel under the ultrasonic action, it is concluded that hardening exponent n of low carbon steel is constant; Hardening exponent N stainless steel has a certain relation with the strain, show the parabolic variation; Strain index N and strain of high manganese steel is linear change. Establish the constitutive equation of low carbon steel under normal and ultrasonic frequency, This equation provides a theoretical basis for the tensile test of low carbon steel, provided with guiding significance and reference value for the application of low carbon steel in engineering practice.
