In this work, the effect of heating rate on phase transformation temperatures was investigated using dilatometry analysis. Continuous and isothermal holding above Ac3 temperature microstructural evolutions in additively manufactured (AM) parts Fe-Cr-Ni maraging stainless steel were studied. The features developed within processes characterized employing electron backscatter diffraction transmis...

Hydroxyapatite (HA) and bioglass (BG) ceramics have become of prime importance in bone tissue engineering. Besides the appropriate composition, microstructure replacement plays a crucial role. In present work, particle composites functionally graded material (FGM) based on HA BG prepared by electrophoretic deposition were thoroughly characterised terms preparation method, sintering process, pha...

Thermal expansion performance is essential for lanthanide magnesium hexaaluminate (LnMgAl 11 O 19 , Ln=La, Gd) top-coating as the thermal barrier coatings materials. In present work, LnMgAl (Ln= La and with magnetoplumbite structure was synthesized by chemical co-precipitation method. The lattice behavior of both samples investigated using a high-temperature X-ray diffraction test combined Reit...

The effect of multi-step austempering treatments on the microstructure and mechanical properties a novel medium carbon high silicon carbide-free bainitic steel was studied. Five different isothermal treatment processes were selected, including single-step above martensite start temperature (at 350 °C 370 °C, respectively), three kinds two-step routes (370 + 300 250 °C). In comparison with adopt...

Magnetoelastic coupling and uniaxial pressure dependencies of the ferromagnetic ordering temperature in quasi-two-dimensional layered van-der-Waals material CrI$_3$ are experimentally studied quantified by high-resolution dilatometry. Clear anomalies thermal expansion coefficients at $T_{\rm C}$ imply positive (negative) $\partial T_{\rm C}/\partial p_{\rm i}$ for applied along (perpendicular t...

Abstract The resistance of alkali-activated materials (AAMs) to degradation processes, particularly the decalcification, was studied in this paper. ground granulated blast furnace slag using various activators with same activator dosage 6% Na 2 O by weight (sodium hydroxide, sodium waterglass and carbonate) subjected testing decalcification (immersion 6M NH 4 NO 3 ) for 84 days. reference sampl...
