The microstructural evolutions and resulted mechanical responses during isothermal holding of multipass hot deformation are essential aspects in the processing high performance titanium alloys. In this work, testing was performed on a Ti-5Al-3V alloy after compression at temperatures 900 °C, 930 °C 960 respectively. Stress relaxation, dilatometer measurements, microstructure examinations (i.e. scanning electron microscope, backscatter diffraction transmission microscope) were employed to...
Dynamic transformation from alpha (HCP) to beta (BCC) phase in a zirconium alloy was revealed by the use of in-situ neutron diffraction during hot compression. The dynamic unexpectedly detected isothermal compression at temperatures 900°C and 950°C (alpha + two-phase region) strain rates 0.01 s−1 0.001 s−1, even though equilibrium states were achieved prior accompanied diffusion Sn phase, which resulted changes lattice parameters characteristic microstructure grains. constant measured...
Post annealing treatment is generally needed for additively manufactured titanium alloy to decompose metastable phases, alleviate residual stress, and improve ductility. In this work, in-situ electrical resistivity line profile analysis of X-ray diffraction were utilized monitoring phase transformation behaviors dislocation evolutions a laser powder bed fusion-built Ti-6Al-4V under post treatment. Besides, hardness tensile tests adopted revealing the effects on mechanical properties. The...
In the present study nine successive ARB cycles were applied on double-layer 1 mm aluminum sheets following three different routes; normal, reverse and cross. Severely deformed studied by XRD EBSD to show evolution of crystallographic textures, while mechanical properties are characterized micro-tensile micro-hardness tests. Results indicate that changing route significantly affects formation texture components in structure, leading macro properties. As asymmetry increases strain route,...
The present study concerns the deformation and fracture behavior of two ferrite–martensite dual phase steels (FMDP660 FMDP780) with different fractions subjected to strain rate (0.001 s−1 1000 s−1) tensile testing. For both steels, yield strength (YS) monotonically increased rates, whereas values ultimate (UTS), uniform elongation (UE) post-uniform (PUE) were maintained stable at low range (0.001–0.1 s−1), followed by a significant increase high levels (0.1–1000 s−1). FMDP780 steel higher...
Liquid holdup and wetting efficiency are essential parameters for design of trickle bed reactors. Both play an important role in reactor performance including pressure drop, conversion, heat transfer. Empirical formulas usually employed to calculate liquid efficiency. However, factors such as particle shape the ability on surface not described clearly traditional formulas. In this paper, actual random packing was built by DEM CFD simulations were performed investigate affecting reactors,...
The present study focuses on the influence of tempered martensite (TM) mechanical properties and fracture mechanisms an ultra-strong dual-phase (DP) steel. steel was subjected to intercritical annealing combined with aging process. high fraction (above ~70 vol%) results in a strength level above 1300 MPa, presence TM ensures good ductility up ~10% total elongation. microstructures tested steels were analyzed by scanning electron microscopy (SEM), transmission (TEM) backscatter diffraction...
