By alloying and thermo-mechanical treatment, a metastable β-type TiNb-4Sn (wt. %) alloy with ultralow Young’s modulus (36 GPa, versus ~30 GPa for human bone) and high ultimate strength ( MPa) was fabricated. We believe that this method can be applied to developing advanced metastable β-type titanium alloys for implant applications. The authors describe the Fe-C stable and metastable diagrams from the physical-chemical metallurgy point of view. The main properties of cast irons are presented and justified for all kinds of cast irons: low cost, excellent castability, mechanical properties depending on the graphite morphology (gray irons) and high wear resistance (white irons).

The ω-phase transformation in metastable β-titanium (Ti) alloys has attracted great attention in the past decade due to its intrinsic complexity and modifying mechanical acial twin boundary (ITB) ω-phase was reported to appear along {} Metastable Alloys book or {} β twin boundaries in metastable β-Ti formation of such ITB ω-phase was Author: Wei Chen, Shuo Cao, Jinyu Zhang, You Zha, Qingmiao Hu, Jun Sun.

In chemical systems, a system of atoms or molecules involving a change in chemical bond can be in a metastable state, which lasts for a relatively long period of time. Molecular vibrations and thermal motion make chemical species at the energetic equivalent of the top of a round hill very short-lived.

Metastable states that persist for many seconds (or years) are found in energetic. Before discussing HEAs specifically, we first consider the general case of a multicomponent alloy, which can reach distinct structural stages of increasing metastability with increasing cooling rate R ().In its equilibrium state (R → 0), a typical multicomponent alloy comprises multiple phases including solid solutions and intermetallics [6,24,68,92,93].Author: Sebastian A.

Kube, Jan Schroers. {} twinning, an unusual twinning mode in other body-centered cubic (bcc) metals and alloys, has been demonstrated to be a fundamental deformation mode in bcc metastable β titanium alloys.

The body-centered cubic (bcc) b-phase is metastable at temperatures below the beta transus temperature, providing these alloys with a wide range of.

High-entropy alloys usually consist of a single phase. This paper reports on a metastable high-entropy alloy that undergoes a partial martensitic phase transformation from the face-centred cubic. The remaining alloys were prepared at CAB by melting Zr and Nb ( and % purity, respectively) in an arc furnace, on a water-cooled copper hearth, using non-consumable electrodes in a Torr Ar atmosphere.

Each alloy was remelted at least six times to favour homogeneity and was cut into small cubes of about 2 mm side length. CoCrFeNi alloy is an exemplary stable base for high entropy alloys (HEAs), but its phase stability is still suspicious.

Here, the CoCrFeNi HEA was firstly identified to be thermally metastable at °C. Composition decomposition occurred after annealed at °C for h. Both interstitial C and N are introduced into a metastable high-entropy alloy (HEA). • The C-N co-doped metastable HEA shows a single FCC phase without HCP martensite.

• Dislocation slip and twinning prevail in the new iHEA without phase transformation. • The new iHEA shows enhanced yield and ultimate strengths at good ductility. Volume is indexed by Thomson Reuters CPCI-S (WoS).Metastable, mechanically alloyed and nanocrystalline materials belong to a group of materials having very promising characteristics.

Prof. Jayanta Das micromechanics of deformation of these advanced metastable alloys. Das has to his credit more than research publications in peer-reviewed journals of international repute, which were cited more than times and has contributed 3 book chapters.

He was the recipient of DAAD. In order to meet these different requirements, the basic properties of such metastable alloys have to be well understood. This was a challenge for many different groups to investigate metastable materials using different production and detection methods.

Thus a lot of knowledge about metastable alloys has been accumulated in the last years. Examples include self-organized metastable nanolaminates, austenite reversion steels, metastable medium- and high-entropy alloys, as well as steels and titanium alloys with martensitic phase transformation and twinning-induced plasticity effects.

Implantation into metals at room and lower temperatures can result in the formation of metastable phases. For low concentrations, ≲1 at. %, substitutional and interstitial solutions have been observed for implantation into Be, Fe, Ni, and Cu.

At higher concentrations, ≳10 at. %, both metastable solid solutions and amorphous alloys have been formed in Fe, Ni, and Cu. Review—Corrosion-Resistant Metastable Al Alloys: An Overview of Corrosion Mechanisms Article (PDF Available) in Journal of The Electrochemical Society (8).

They cover alloys and ceramics, nanomaterials, and synthesis and properties. Specific topics. Heat treatment of metastable beta titanium alloys involves essentially two steps—solution treatment in beta or alpha+beta phase field and aging at appropriate lower temperatures. High strength in beta titanium alloys can be developed via solution treatment followed by aging by precipitating fine alpha (α) particles in a beta (β) matrix.
