The quenching and partitioning (Q&P) process is a novel heat treatment for the development of advanced high strength steels that is raising an elevated interest by steel makers and steel researchers around the world.
These new advanced high strength steels (AHSS) include TWIP steels [1], containing 15-30 wt.% of manganese, and steels with chemical compositions closer to conventional TRIP or DP steels but processed by novel heat treatments, like the high-strength bainitic steels [2-3] and the new quenched and partitioned steels [4-5].

Their combination can therefore be very fruitful and prominent to achieve coatings, which results in their most recent and advanced applications.
Introduction Thermal spray is often considered as a basic and not very advanced process (Fig. 1).
The latter is more advanced and original, though the recent development of LAser Shock Adhesion Testing, namely LASAT.

This article presents an overview on the basic principles and recent advances in the ultrasonic cavitation based processing of MMNCs with a particular emphasis on identifying relationships amongst processing variables, microstructural parameters and mechanical properties.
Introduction Metal matrix composites (MMCs) are advanced hybrid materials in which tailored properties such as excellent strength-to-weight ratio, which is not easily attainable in base materials, are realized by utilizing the better ductility and toughness of the metal/alloy matrix in presence of higher modulus and hardness of ceramic reinforcement [1,2].

The part shown on the left is a 737 aluminum Nacelle assembly, the Inlet on the right is an advanced FSW joined and SPF formed single piece prototype test part with 6 FSW welds.
Composite materials are being used to build the world’s most advanced military aircraft such as the F/A-22, B-2B, F-15E and the Joint Strike Fighter.
The sheet size limit is a substantial drawback for the emerging commercial airplanes built primarily from CFRP materials because of the engineering design advantages of large monolithic alternatives, such as using SPF titanium 6Al-4V in hybrid CFRP assemblies.
