A50 formulation was processed as described by Fortulan et al. 2011[03] according to Table 1.
The raw materials selected for this study were defined by Fortulan et al. 2011 [03]: Clay São Simão (Minasolo, batch 078/92, #325 mesh), potassium feldspar (Minasolo, batch MCK 200, 13:36 wt% K2O, #325 mesh) alumina-α 5S-G (Alcan, batch 24, 0.95 m2/g surface area, 4.08 µm equivalent spherical diameter) and kaolin (Minasolo, batch MCP-325, 45.5 wt% SiO2, #325 mesh).

Some literature [4] reported that the fraction of carbon-enrich retained austenite is determined by the content of Si and Al.
Because the alloying elements such as Si and Al can avoid the carbide precipitation during the partitioning step.

(3) Excellent mechanical properties of low Si steels without Al can be obtained by Q-I-Q-T process, due to the refining multiphase substructure, especially small bainite laths led to the good toughness and plasticity formed during the isothermal step in Q-I-Q-T steels.

Shah et al. (2010) theoretically discussed the impact of fracture orientation near the wellbore and found that the well performance is dramatically affected by the fracture forms [7].

The corrosion products are composed of Mo, P, Al and O.
The chemical composition of these layers was following: P, Mo, probably Al and O.

According to Tran et al., silver nanoparticles (AgNPs) have higher electrical and thermal conductivity than other metals [1].
This band gap is equal to that obtained in a study by Li et al., which is 2.28-2.55 eV [28-31].

Box 4200, 90014 Oulu, Finland 2University of Texas at El Paso, Dept. of Metallurgical and Materials Engineering, Engineering Building, El Paso, TX 79968-0521, USA Keywords: Direct quenching, hardebility, ideal critical diameter, thermomechanical rolling, finish rolling temperature, quenching and partitioning, martensite, retained austenite, bendability.
In the case of a high-aluminium steel Al-Mo (0.19C-0.51Si-1.98Mn-1.06Al-0.52Cr-0.21Mo), the austenite contents varied in a narrow range of 7-9%, regardless of the TP (=TQ) or austenite state.
Unlike in the case of steel High-Si steel, High-Al steels such as Al-Cr (0.21C-0.56Si-1.9Mn-0.92Al-1.1Cr) and Al-Cr-Ni (0.22C-0.55Si-1.5Mn-0.85Al-1.2Cr) in the unstrained condition contract over ≈20 s after the start of stage I, presumably due to interface migration from austenite to martensite, as discussed in literature [19].
It seems that not only the T28J temperature is low, but also the upper shelf energy KV(US) is quite high in the Ni variant (Al-Cr-Ni).
The advantage of strained austenite in respect of the refinement of martensite packets/blocks/laths resulted in improved mechanical properties both for Si- and Al-bearing steels.

Recently, a new method, termed metal-assisted etching, to form porous silicon was proposed by Li et al. [5].
A thin metallic film (Au, Pt, Al, Pd …) is generally deposited directly on a silicon surface prior to immersion in a mixture of HF and oxidizing agent.
Li et al. have obtained a different morphology: pores with columnar structure were formed when a Pt-coated p-type silicon was subjected to etching in the solution 1:1:1 EtOH:HF(49%):H2O2(30%) for 30 s [5].

The problem space and boundary conditions for the electrical and thermal problem are modeled similarly to the work by Green el al. [8], and the lateral microfluidic microelectrodes structure is shown schematically in Fig.1.
