Hot Rolling Process

The 304 austenite stainless steel and low carbon steel clad plate was fabricated by casting and hot rolling process. The mechanical properties and interface shear strength of clad plates with different thickness after rolling were investigated in detail. The microstructure characteristics of the clad interface were observed by SEM (Scanning Electron Microscope). The phases and chemical composition were analyzed by XRD (X-ray diffraction) and EDS (energy dispersive spectroscopy). Based on the results, the mechanical properties and interface shear strengths meet the requirements of national standards. No visible cracks were observed in the clad interface after bending test. Cr3C2precipitates, Fe3O4oxides and Fe-Cr intermetallic compound were distributed around the interface of clad plate after casting, but a good metallurgical bonding was achieved after hot-rolling.

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.
