A New Phase in a Complex Alloy Steel
Nature, 1958DURING investigations into the age-hardening of a steel containing 12 per cent chromium, 4 per cent nickel, 3 per cent manganese and 2.5 per cent silicon, a phase not previously reported was extracted electrolytically. This new constituent has been arbitrarily designated S phase.

Thermodynamic Calculation and Experimental Study on Complex Phase Steel
Advanced Materials Research, 2013Using Thermo-calc software, transformation points as well as bainite starting temperature of the CP steel studied in the present work were calculated. Based on the measured CCT curve, the steels were treated at different conditions using Gleeble-3500 thermal simulation tester.

Microscopy (Oxford, England), 2015
For optimizing the microstructure of complex phase (CP) steels, characterization using scanning electron microscopy (SEM) is powerful because it allows observations from very low to high magnification. SEM specimens of steels are often etched in order to distinguish between the different phases by producing topographic information.

Microstructural evolution of a hot-rolled microalloyed complex phase steel
Canadian Metallurgical Quarterly, 2016ABSTRACTThe current study examines a grade of hot-rolled and continuously cooled complex phase sheet steel comprised of polygonal ferrite (PF), granular bainite (GB) and lath bainite (B). The quantity of each constituent phase depends on the thermomechanical processing conditions, which vary between commercially produced sheets.

Challenges of quantitative phase analysis of iron and steel slags: a look at sample complexity
Powder Diffraction, 2023Quantitative phase analysis (QPA) of slags is complex due to the natural richness of phases and variability in sample composition. The number of phases frequently exceeds 10, with certain slag types (EAF, BOF, blends, stainless) having extreme peak overlap, making identification difficult.

Abstract We examine the effect of transformation sequence on the microstructure evolution and mechanical properties of complex phase steel consisting of bainite and martensite. Formation of martensite prior to bainite transformation provides uniform lath-type mixture of constituent phases, but preceding isothermal bainite transformation produces ...

Complex phase (CP) concept is justified based on the improvement of stretch flangeability (hole expansion) due to replacement of martensite, at least partially, by bainite. Relationship between microstructure and mechanical properties of CP steels is presented as well as recommended for processing parameters to obtain bainite fraction, keeping in mind ...

Complex-Phase Automotive Steels
Abstract Over the last two decades, the automotive industry has faced increasing challenges concerning passenger safety, vehicle performance, and fuel economy. These challenges have been met via an increasing application of higher strength grades of steel, called advanced high-strength steels (AHSS), for forming complex parts.Claudio Bunte +2 more
