The microstructure and mechanical properties of an Fe-0.24C-1.4Mn-1.4Si steel were investigated after combining ultrafast heating (UFH) at a rate 500 °C/s followed by fast cooling to room temperature (DQ) or quenching partitioning processes (Q&P). Two peak temperatures studied, annealing into the intercritical range above AC3 temperature. After quenching, resulting microstructures revealed that...

The composition dependence of ferrite growth kinetics in Fe-C-X ternary alloyed steels, where X = Ni, Mn, Mo, Cr, Si, was investigated using a high-throughput approach. Compositionally graded samples were subjected to situ time- and space-resolved X-ray diffraction during intercritical annealing. To this end, diffusion couples created between binary Fe-C different alloys, hot uniaxial compressi...

Gout is a frequent inflammatory disease induced by the deposition of monosodium urate crystals in joints and extra-articular tissues. The natural history of the disease includes four different phases: asymptomatic hyperuricemia, acute attacks, intercritical phase, and chronic tophaceous gout. Imaging techniques have several applications in the diagnosis, clinical monitoring and management of th...

The aim of this study was to evaluate tensile properties low and medium carbon ferrite -martensite dual phase steel, the effect cryogenic treatment at liquid nitrogen temperature (-196 ºC) on its properties. Low steel (C12D) steels (C32D & C42D) were used in work. For each grade, five groups specimens prepared according type heat treatment. first group normalized, second normalized subseque...

Medium Mn lightweight steels with a relatively higher content of 9–12 wt% have been actively developed recently to meet the demands crashworthiness and vehicles. In this study, combined intensive quenching (IQ) deep cryogenic treatment (DCT) was first proposed achieve microstructural homogeneity as well final strength–ductility synergy medium segregation bands, together comparison conventional ...

The effects of process atmosphere oxygen partial pressure (pO2) on the preimmersion surface structures, interfacial reactive wetting products, and mechanisms two prototype (0.15–0.20)C–(5.6–5.9)Mn–(0.4–1.9)Al–(1.1–1.5)Si–(0–0.6)Cr (wt%) third-generation advanced high-strength steels during continuous hot-dip galvanizing are determined. In this study, two-stage thermal processing routes employed...
