A constitutional study of a dual phase steel containing 12% chromium
This thesis involved a study of the phase transfonnations in a chromium containing corrosion resistant dual phase steel, designated 3CR12. The objectives included the detennination of time-temperature-transformation (TTT) diagrams for the transformations between austenite and ferrite and an …

The microstructure and some phase transformation characteristics of the dual phase steel 3CR12
… metallography have been used to establish the phase transformation diagram of a steel containing 12% chromium and 0,03% carbon. A dual phase material with attractive mechanical properties and adequate corrosion resistance can be achieved by careful control of alloy content and heat treatment. …

The influence of elemental partitioning on hardness in a 12% chromium dual-phase steel
… the annealing treatment in the production of dual phase steels, partitfoning of alloying elements can occur depending on competitive solubility in the ferrite and austenite for the specific partitioning species. An investigation of the partitioning of substitutional elements was considered …

Damage and repair evolution of cold formed linepipe steel
… can be achieved by heat treatment of linepipe steel. A set of unified viscoplastic constitutive equations was developed to simulate microstructural evolution and the effect on mechanical properties due to cold deformation followed by annealing. In addition, practical experiments have been …

Edge Fracture Prediction Of Dual Phase Steels With Consideration Of Microstructures
<p>In recent years, Advanced High Strength Steels (AHSS) have been used for the lightweight structural design and manufacturing in automotive industry. This class of sheet metals are prone to edge fracture during stamping production, and the fracture often occurs at much lower strain than that …

Theory and significance of retained austenite in steels
… austenite following the bainite and martensite phase transformations have been examined, together with the influence of retained austenite on the properties of low alloy steels. It was found that the upper and lower bainite transformations are separate reactions, although both involve a …
