Abstract This is a viewpoint paper on recent progress in the understanding of microstructure–property relations advanced high-strength steels (AHSS). These alloys constitute class high-strength, formable that are designed mainly as sheet products for transportation sector. AHSS have often very complex and hierarchical microstructures consisting ferrite, austenite, bainite, or martensite matrix duplex even multiphase mixtures these constituents, sometimes enriched with precipitates....
Structural material development for lightweight applications aims at improving the key parameters strength, stiffness and ductility low density, but these properties are typically mutually exclusive. Here we present how overcome this trade-off with a new class of nano-structured steel - TiB2 composites synthesised in-situ via bulk metallurgical spray-forming. Owing to nano-sized dispersion particles extreme density obtained by formation rapid solidification kinetics has mechanical...
The presented study provides an overview of the current research achievements and emerging market bio-based thermosetting polymers. Environmental attributes related to polymers trigger a steadily growing interest in this novel promising field. Due their importance among thermosets terms composite applications quantity, review focusses on epoxy unsaturated polyester resins. Current studies are mainly concerned with alternative renewable raw materials substitute fossil content synthesis...
Successful metallurgical design of metal-matrix-composites relies on the knowledge intrinsic property profiles metal matrix and especially compounds employed for particles, whiskers or fibres. In this work we compiled key properties melting point, bulk modulus, shear Young׳s density, hardness, Poisson׳s ratio structure/space group from widespread literature data most relevant compound types, i.e. borides, carbo-borides, carbides, oxides, nitrides intermetallic phases.
We studied the effect of Ni additions up to 15 wt% on microstructure and properties cast hot-rolled Fe – 24 Cr 1.8 B (wt%) steels. The base alloy without addition reached a stiffness/density ratio 32.7 GPa g−1 cm3, 400 MPa yield strength, 800 ultimate tensile strength 20% ductility. Increasing concentration resulted in change lattice parameters mean average size in-situ formed M2B type boride particles. It also altered matrix from ferritic towards martensitic then austenitic constitution,...
High modulus steels, metal matrix composites of ductile steels with embedded boride particles to increase the stiffness density ratio, are promising materials for future lightweight design solutions. One key requirement maturing them towards industrial application is their suitability improving surface hardness. In this study we investigated effects low-pressure carburizing and plasma nitriding on microstructure mechanical properties selected Fe-TiB2- Fe-Cr-M2B-based high steels. Nitriding...
In their supply chain strategy in 2003 Wellstream decided to expand the application of Nylon (PA) grades for off-shore use order move away from a single source supply. Degussa have developed new grade PA 12 offshore applications, such as flexible pipes. joint effort International Limited and AG performed qualification test programme on this grade. On basis these tests has obtained Lloyds “Certificate Material Qualification Use Polyamide Grade - VESTAMID® LX9020 non-Bonded Flexible Pipes”....
