Structural and Near-IR Luminescent Properties of Erbium-Containing Coordination Polymers

The near-IR luminescence properties of two ErIII-containing coordination polymers, namely, [Er(btc)(H2O)5·3.5H2O] [(btc)3– = 1,3,5-benzenetricarboxylate] and [Er2(bdc)3- (H2O)4] [(bdc)2– = 1,4-benzenedicarboxylate] were investigated with the aim of testing ...

Tempering effects on three martensitic carbon steels studied by mechanical spectroscopy

Daniele Mari, Robert Schaller

Tempering effects have been studied in three martensitic carbon steels by mechanical spectroscopy. The mechanical-loss spectra present a relaxation peak similar to the Snoek-Koster peak in ferrite. The peak amplitude decreases upon tempering, indicating a ...

On the relationship between the microstructure and the mechanical properties of an ODS ferritic/martensitic steel

Amuthan Ramar

In the quest of materials for the first wall of the future fusion reactor, it has been shown that oxide dispersion strengthened (ODS) ferritic / martensitic (F/M) steels appear to be promising candidates. The inherent good mechanical properties supported b ...

About Initial Solidification In Continuous Casting Of Steel

Wilfried Kurz

High solidification velocities, high temperature gradients and strong melt flow characterize the first moments of solidification in a continuous caster. The beginning of shell growth in the meniscus area is determined by the local heat flow, the strength o ...

Estimating localised corrosion resistance of low alloy stainless steels: comparison of pitting potentials and critical pitting temperatures measured on lean duplex stainless steel LDX 2101 after sensitisation

Two different methods for estimating the corrosion resistance of low alloy stainless steels are compared: critical pitting temperature according to a modified ASTM G150 with a low chloride concentration (0.1M), and pitting potentials from polarisation curv ...

Effect of irradiation on the microstructure and the mechanical properties of oxide dispersion strengthened low activation ferritic/martensitic steel

Nadine Baluc, Amuthan Ramar

Ferritic/martensitic (F/M) steels show good resistance to swelling and low damage accumulation upon irradiation relative to stainless steels. 0.3 wt% yttria particles were added to the F/M steel EUROFER 97 to produce oxide dispersion strengthened (ODS) ste ...

Alloying effects on microstructure and mechanical properties of high volume fraction SiC-particle reinforced Al-MMCs made by squeeze casting infiltration

Philippe Buffat, Cyril Cayron

The mechanical properties of high volume fraction SiC-particle reinforced Al-based metal matrix composites (MMCs) produced by means of pressurized liquid metal infiltration (squeeze casting) are shown to be triggered by matrix alloying and heat treatment p ...

Constitutive behavior and fracture properties of tempered martensitic steels for nuclear applications

Raul Alejandro Bonadé

In this study, the tensile and fracture properties and the microstructure of the reduced-activation tempered martensitic steel Eurofer97 have been investigated. This technical alloy is a 9%Cr steel developed within the European fusion material research pro ...

Microstructural development under irradiation in European ODS ferritic/martensitic steels

Nadine Baluc, Amuthan Ramar

Oxide dispersion strengthened steels based on the ferritic/martensitic steel EUROFER97 are promising candidates for a fusion reactor because of their improved high temperature mechanical properties and their potential higher radiation resistance relative t ...

The effect of point defects on the martensitic phase transformation

Jian Wang, Yi Wang

Martensitic Ni-Ti was observed to transform to the austenitic phase due to defects introduced either by ion or electron irradiations at a temperature where the martensitic phase is normally stable. The phenomenon was studied by molecular dynamics simulatio ...
