Conventional heat treatment is not capable of converting a sufficient amount retained austenite into martensite in high-carbon or and high-alloyed iron alloys. Cryogenic induces the following alterations microstructures: (i) considerable reduction amount, (ii) formation refined coupled with an increased number lattice defects, such as dislocations twins, (iii) changes precipitation kinetics nano-sized transient carbides during tempering, (iv) increase small globular carbides. These...
One of the prevailing problems for materials produced by powder metallurgy is contamination from various sources. This work deals with influence process parameters and presence control agents (PCA) on level means mechanical alloying (MA) technology, densified spark plasma sintering (SPS). The equiatomic CoCrFeNi high-entropy alloy (HEA) was manufactured said methodology. For clear comparison, 316L austenitic steel milled identical conditions as a reference material. Both were in argon...
The processing conditions for preparing well dispersed silica-graphene nanoplatelets and oxide (GONP) composites were optimized using powder colloidal routes. Fully dense silica-GONP with up to 2.5 vol% loading consolidated spark plasma sintering. GONP aligned perpendicularly the applied pressure during fracture toughness of increased linearly increasing concentration reached a value ∼0.9 MPa m1/2 loading. Various toughening mechanisms including necking, pull-out, crack bridging, deflection...
Bacterial infection associated with medical implants is a major threat to healthcare. This work reports the fabrication of Copper(II)–Chitosan (Cu(II)–CS) complex coatings deposited by electrophoretic deposition (EPD) as potential antibacterial candidate combat microorganisms reduce implant related infections. The successful Cu(II)–CS on stainless steel was confirmed physicochemical characterizations. Morphological and elemental analyses scanning electron microscopy (SEM) energy-dispersive...
Polycrystalline transparent magnesium aluminate "spinel" ceramics were fabricated by hot-pressing and hot isostatic pressing (HIPing) using commercially available MgO Al2O3 powders. content of spinel was systematically changed that can be expressed as MgO·nAl2O3 with n=1.0, 1.5 2.0. UV/visible near-IR wavelength region light reflection transmission behaviors the quantitatively correlated to their microstructure account for optical quality materials. The stoichiometric ceramic n=1.0 revealed...
Abstract Room‐temperature hydro‐pressure‐driven densification of amorphous silica (nanoparticles and microbeads) is developed. This technique inspired by biological silicification with reference to dissolution, precipitation, hardening mechanisms. Cold sintering based on uniaxial pressure taken as a benchmark. Starting from green‐body relative density 70%, exceeding 99% achieved adding distilled water or caustic solution an powder under hydrostatic 450–600 MPa for 5–30 min. Translucent...
