Introduction U–Mo dispersion fuels in Al-alloys are being developed to fulfill the requirements of low enriched uranium in research and test reactors.
During irradiation and thermal annealing, an interaction occurs between the U-Mo alloy and the surrounding aluminium matrix.
For SP2, an automatic optical adjustment system enables to control the size of the windows aiming for local micro analysis.

The aim of this study is to investigate and optimize the friction stir process to produce localized particle reinforced zones in cast aluminum components.
The grey color represented the aluminum base, and those larger lighter particles (~2 μm) were Al-Cu compound precipitations that were broken up during FSP.

Commercial applications of superplastic forming are restricted to aluminium and titanium alloys and to a lesser extent certain steels and nickel alloys.
In vitro properties of SPF titanium alloys - immersion in simulated body fluid.
The apatite on SP700 alloy and alloys treated with Deguvest are clearly less dense.
Based on the current observations and the findings of Scrimgeour it is possible to make the tentative observation that since pyrophosphates are the dominant phase in Wirovest investment, these compounds may be responsible for the increased apatite density.

The Fe-O functional group, which is a characteristic of magnetite compounds, is at wavenumber 752 cm-1 [16], [17].
In this study, the aim of adding the PEO/PMMA has been used to control the stabilization of particle size and control the design of the crystal structure still on the octahedral structure [23].

Introduction Over the last two decades, Fe-Mn-Si-Cr-Ni-Co shape memory stainless steels (SMSS) have drawn considerable attention as a cost-effective alternative to non-ferrous (NiTi and Cu based) conventional shape memory alloys.

The microstructure of the MZ in a joint is strongly affected by two phenomena occurring during solidification, i.e, dendritic growth and solute partitioning, with consequent formation of carbides, borides and other metallic compounds.
Low melting compounds may give rise to micro-cracks after post-welding heat treatments [10] and local residual stresses arise in the MZ which can induce the failure of mechanical parts [11-12].

At last, the experiments have been set up to verify the simulations.Nowadays, finite element method with software simulation can help engineers to predict the springback angle.Compare to the trial-and-error method, the FEM method can save a lot of time and money.It is important to minimise the springback angle and longitidianl strain in the roll forming porcess.The aim of this paper is to figure out the spring back angles with different materials in roll forming prcess and the influence of the factors on bow defect. 1.

This work aims at elucidating the combined effects of prior austenite deformation and Cr content on continuous cooling phase transformation, microstructure and hardness in the case of a newly developed low-carbon bainitic steel.
Compared to the more highly alloyed steel A, hardness is more sensitive to CR and austenite deformation (see Fig. 2c and d).
Over the wide range of cooling rates 2 to 80 °C/s, hardness increased from 207 to 261 HV, when alloying with 1 wt.% Cr, but only from 297 to 337 HV when alloying with 4 wt.% Cr
