We propose a computational investigation of Ni-alloying impact on Fe-C martensite ageing, at the atomic scale. Using Climbing Image Nudged Elastic Band technique, we showed repulsive nature Ni-C pairwise interactions in α-iron, and demonstrated that Ni alloying lowers migration energies force dipole tensor components associated to an interstitial carbon α-iron. Computed values interactions, wer...

The microstructure plays a crucial role for steel semi-solid forming process, and particularly for the steel thixoforging process, since it determines the thixotropic flow behavior of materials in the semi-solid state. Therefore, it is necessary to well understand the microstructure evolution during high speed heating and forming. Classically, it is investigated on a solid material quenched fro...

The present work has as main aim to make a small introduction about the types of steels, specially the ones used in the construction industry. This material is appreciated in construction due to its many advantages as strengths, resistance, adaptability and flexibility in design, durability, recyclability,...; even thou its also has week points like a low resistance to fire, weak against corros...

The ferrochrome alloy is produced by electric arc melting of the mineral chromite (FeCr2O4). It is largely used for the production of stainless steels. Increasing the amount of chromium content in the steel allows for increased corrosion and oxidation resistance. Other alloying elements, such as nickel (Ni) or molybdenum (Mo), aid in making the steel more passive and increasing its stainless pr...

The thermal expansion coefficient of Al3Sc and Al3(Sc0:75X0:25), where X is Ti, Y, Zr or Hf, was measured by dilatometry between 25 and 1000 C. The measured value, ð16 1Þ 10 6 K , is constant between 25 and 900 C and insensitive to alloying element. Good agreement is found with a literature value determined from first-principle cal-
