Aluminium alloy based metal matrix composites are being extensively used in the aerospace, automobile, defense, marine and electronic industries owing to their excellent strength, high resistance wear, corrosion better thermal stability. Many investigators have explored different aluminium series composites, like heat treatable AA2024, AA6061 AA7075 since properties of these alloys can be easil...

Over the past few decades, aluminium (Al) has been considered to be beneficial for castability but detrimental creep resistance of magnesium (Mg) alloys. However, an excellent achieved in a die-cast Mg3.5RE(La,Ce,Nd)1.5GdMnAl alloy, with super low steady-state rate (SCR) 1.35 × 10?10s?1 at 300 °C/50 MPa. Compared counterpart Al-free Mg3.5RE(La,Ce,Nd)1.5GdMn SCR decreased by 71%. The synergistic...

Treatment is an operation or combination of operations involving typical heating and soaking at a temperature for a period of time and methods. The aim is to obtain a desired predetermined property like hardness. Knowing the hardness of any metal or alloy is important, as this value gives you an indication of its ability to form and maintain a shape and is also a guide to its durability. To ens...

Ductile iron is one of the most important engineering materials, in view of its excellent castability, signifi cantly better mechanical properties and low cost [1, 2]. It represents the fastest growing segment of the iron market. In the medium term, it is to be expected that the market share of nodular iron will level off at 40 % to 45 % [3]. Achieving the full potential of ductile iron require...

Eutectic alloys are natural in-situ composites with near-equilibrium structures, impressive strength-ductility trade-off, and perfect castability. In the current study, novel eutectic Al-Cr-Nb-Ti-Zr refractory high entropy (RHEAs) were designed using a CALPHAD (CALculation of PHAse Diagrams) approach. A starting Nb30Ti40Zr30 (at.%) alloy was based on single-phase bcc solid solution. Alloying Cr...

Novel magnesium-based materials are ideal candidates for use in future aviation vehicles because they extremely light and can therefore significantly increase the range of these vehicles. They show very good castability, easy to machine be shaped into profiles or forgings used as components next generation aerial vehicle construction. In case a large number identical components, high-pressure d...
