Percent Manganese

The effects of phosphorus on the annealing texture, plastic anisotropy, and mechanical properties of low-carbon steels containing 0.11 percent manganese have been studied. Both vacuum-melted and air-melted heats, with phsophorus additions up to 0.12 percent, were used. Results show that with a cold reduction of 80 percent, followed by annealing at temperatures in the range 710 to 820°C, the plastic strain ratios, rm and ∆r, as well as the strength of the steels were substantially improved by phosphorus. Annealing at the intercritical temperatures 780 and 820°C further improved the strain ratios. The strong tendency for phosphorus to segregate at the subgrain and grain boundaries is believed to have played an important role in controlling the formation of annealing textures in these steels.

Bainitic Steels

The influence of Ti oxide on the toughness of heat affected zone for low carbon bainitic steels has been investigated. The optical microscope, SEM and TEM were used to analyze the composition, size and distribution of the inclusions, and the microstructure and mechanical properties after welding thermal simulation were also investigated. The effect of Ti oxide inclusion on the transformation of acicular ferrite has also been studied. The results show that after the melting with Ti dioxide technique the inclusion is complex, in the core is Ti oxides about 1-3 micron and around it is MnS. It has been found the acicular ferrite can nucleate at the inclusions and the Ti oxide inclusion will promote the nucleation of acicular ferrite, and the acicular ferrite will block the growth of bainite. Therefore by introducing the Ti oxide in the steels the microstructure of HAZ could be refined markedly therefore the toughness of HAZ can be improved evidently.

Abstract Steels with martensitic and tempered martensitic microstructures, though sometimes perceived as brittle, exhibit plasticity and ductile fracture behavior under certain conditions. This chapter describes the alloying and tempering conditions that produce a ductile form of martensite in low-carbon steels. It also discusses the effect of tempering temperature on the mechanical behavior and deformation properties of medium-carbon steels.
